Testimonials

I had total knee replacement in both knees by Dr. Berliner. He is an excellent surgeon and was great at explaining and guiding me through what to expect. He welcomed my questions and understood my concerns. His office staff was amazing in every situation…….Best decision I ever made. (5 Star Review on Google from A.G.)

Dr. Berliner did an anterior hip replacement on me in January and I could not be happier with the results. He is a complete professional, treating me with the upmost respect and care. He is patient, kind, competent and totally without ego. I highly recommend him. (5 Star Review on Healthgrades by J.F. of Darien, CT) September 13, 2019

Dr. Berliner at ONS is a superb physician and I can not recommend him highly enough. Knowledgeable and compassionate with a sense of humor. I had two anterior hip replacements in 10 months and couldn’t be happier. Run, if you can  to Dr. Berliner. (Patient comments on ONS Facebook)

With two hip replacements in 10 months I cannot say enough about Dr. Berliner and ONS. Professional, caring and superb quality of care. Would recommend Dr. Berliner and ONS to anyone with orthopedic concerns. (5 Star Review on Google from L.G.)

I came across Dr. Berliner, who has a special training to perform anterior hip replacement surgery. This surgery  shortens recovery time and it is also less painful. When I met Dr. Berliner, I knew I was in great hands. He explained everything to me in great detail and was very patient with me. I felt so comfortable that I scheduled my surgery before leaving the office. My surgery went smoothly. I was home next day. I highly recommend him! He is an exceptional orthopedic surgeon! Thank you very much. (5 Star Review on Healthgrades from Y.)

It has been 8 weeks since my hip replacement with Dr. Berliner. He gave me my pre-pain active life back. I am completely pain free and have resumed my sporting activities. I walk at least a mile per day, resumed Pilates and even started to play a little golf. Everyone is amazed with my recovery ahead of schedule. I consider Dr. Berliner an excellent and compassionate surgeon. His communication was clear and informative. His confidence helped me make the decision to undergo the procedure. He made the process less scary than I thought it would be. I am very thankful to Dr. Berliner and the staff at ONS and will gladly recommend him to others and would entrust him with another procedure if needed. (Review on ONS Facebook by A.M.)

Dr. Jonathan Berliner did anterior double hip replacement on my husband and we are both so impressed! His compassion and professionalism is amazing! We are both so grateful for his work and expertise! Thank you Dr Berliner! (5 Star Review on Facebook from D.S.B)

Dr. Berliner is a very nice man who answered all of my many questions prior to and after my surgery. It has been 4 weeks since my anterior full hip replacement and I am doing very well. I was pleased with his bedside manor, he had no arrogance and I never felt rushed at an appointment. Most of all, with Dr. Berliner’s muscle sparing anterior technique, I was able to do a full squat with no pain only 8 days after my surgery and I was twirling my cane like Charlie Chaplin on my daily walk! (5 Star Review on Healthgrades from L. in New Canaan, CT)

I was having severe left hip pain and went to Dr. Berliner for a second opinion. I ended up having him do my anterior hip replacement this past January, and I am so pleased. He is professional and compassionate, and an excellent surgeon. I was a nervous wreck since I never had surgery before, nor had I ever even been in a hospital in my 67 years of living! He is wonderful, bottom line. I need a knee replaced too, and he will be doing that when the time comes! (5 Star review on Healthgrades from P.P. in Norwalk)

At 34, I was young to need a hip replacement, but needed one regardless. I am very grateful to have found Dr. Berliner. He handled a complex case swiftly and adeptly, with a calm confidence unparalleled in other surgeons.

The post-operative pain was negligible compared to the amount of pain I was in pre-op. Within a week, I was walking with a cane, something I hadn’t been able to do during the 5 months prior.  Evident of his people skills, he even handled my post-operative anxiety about complications occurring like a pro, alleviating any concerns.

I sent the post-op images to a relative overseas who is also an orthopedic surgeon. He said Dr. Berliner did “brilliant work.” – I can only agree.  Thank you. (L.D.)

Dr. Berliner is absolutely the best! I did much research before having my total anterior hip replacement and because he is young and starting his practice, I could not find much information on him. I took a chance because I had a good feeling and he did an outstanding job with my surgery. He was very present and available and didn’t have the doctor ego where he wouldn’t answer questions etc. etc. He was nothing short of incredible. I’m so thankful to him and all the team at ONS. (5 Star Review on Healthgrades by M.F. of Danbury, CT)

When I first came into your office, I was nine months post-operative from a  total knee replacement from a doctor in Florida. He did a horrible job. I was +70/65 bend. Just horrible. I met Dr. Berliner after he came highly recommended. He changed my life on 12/15/17. He did a total revision on my right knee. I am now 8 days post operative and bending 80 already and -5. I am so blessed for him.  It was a very tough surgery and he did an amazing job.  (J.B., 5 Star Reveiw on ONS Facebook page)

Testimonials

The ONS surgical team, physical therapy team and admin are all amazing. I had the good fortune of working closely with Dr. Delos and Tanya K., DPT (Greenwich PT Director), and they, and all on their team/staff were kind, knowledgeable, professional, efficient – – and it is clear they genuinely care about their patients and their improvement! They also give you the confidence and support you need to get through your recovery. From the moment you hobble in the door to the moment you walk out (better than ever), each member of the team makes a point get to know and be there for each individual client – particularly, so if you have a question or any need anything at all, someone on the team can assist you promptly/safely. They definitely go above and beyond in their patient care and it shows in the results! I never expected my recovery to be so pleasant and faster than expected! (5 Star Review on Google from S.S.)

Dr. Delos explained my displaced meniscus injury and his recommendations for fixing it so that I could get back to doing what I could before. He was very clear and very positive in his description, diagnosis and surgery to be done. I had been suffering for over a month and received several other recommendations from another doctor. I felt confident that the surgery he recommended would fix the issue. He also was able to get me in for the surgery within the week. Arthroscopic surgery went well, physical therapy went well and I was able to walk without a cane and drive in 2 weeks. No pain after surgery. It was important to get to PT quickly after surgery and to follow the plan outlined by the therapist. I would recommend Dr. Delos for a knee injury.  (5 Star Review on Healthgrades, Aug. 6, 2019)

I recently had my ACL done by Dr. Delos. It was a great experience and the surgery went really well. I am really happy with how it is healing and how quickly I was able to get back to regular life.

Dr. Delos is an amazing man and surgeon. I had concerns about another physician that I was going to and heard great things about Dr. Delos, so I went to him for a second opinion. He was completely straight with me and reviewed everything with me. I  didn’t feel the least bit rushed. He took all the time that I needed. I walked away knowing what was wrong with my knee and subsequently, chose him for my total knee replacement. His bedside manner is wonderful and he is compassionate, caring and confident. He made sure that I knew exactly what was wrong and how he would treat it. I had ad my surgery and  am 6 weeks out. I’m already driving and back to work! His office staff are all great, and my PT is going well. They are all so supportive, as Dr. Delos is. I would recommend him to anyone. I can’t say enough wonderful things about him. Thank you Dr. Delos!!!!!! I’m a new woman with a brand new knee!! (5 Star Review on Google from E.N.) 07/10/2019
Dr. Delos was fantastic. He made an expert repair on my torn tendon and the follow up and follow through with the Dr. and with ONS PT was outstanding. (5 Star Review on Healthgrades from J.M.  Jul 30, 2019)

Dr. Delos is an excellent person and doctor. Always on time for appointments. Awesome bedside manners. I never felt rushed. Always took the time to answer all of my questions. The facilities and staff were equally professional.  (5 Star Review on Healthgrades) September 11, 2019

My son had a torn ACL.  Dr. Delos is a great doctor, surgeon and has wonderful communication skills. Highly recommended. (5 Star Review on Google from C.R.)

My experience with ONS and Dr. Delos has been outstanding in every way. I had been suffering with osteoarthritis in my knees and was looking for a second opinion. During my first appointment with Dr. Delos and after his review of my x-rays and my medical history, he thoughtfully explained all of my options and we worked together to determine next steps. My condition was advanced and I had already tried medication and physical therapy which had not relieved my pain. I tried cortisone injections next, but this too proved to be of limited value and my ability to walk and degree of pain worsened. I ultimately decided to request bilateral knee replacement. Again, Dr. Delos went over everything with me in a patient and clear manner with all of the risks and benefits identified. I felt confident and prepared after our appointment and I knew that if I played my part both in prepping for and participating in the hard work after surgery, that I could return to a normal life. The entire ONS team was incredibly organized and helpful in every way. In no time, I was scheduled for surgery, booked for a pre-surgery class and all my questions were answered. Each person I interacted with was friendly, competent and caring. My surgery at Greenwich Hospital was a complete success. Dr. Delos and his team did an amazing job and the staff at the hospital was fantastic. I could not have asked for more. Today, 5 months after surgery, I am walking normally and without pain. I am continuing to exercise and follow the advice provided by my physical therapists and with each month that goes by I continue to be amazed at how different my life is than it was at this time last year. This surgery gave me my life back and I am forever grateful to Dr. Delos and his team of dedicated professionals for making that happen. (5 Star Review on Google from E.R.)

After years of PT, 2 surgeries that did not help, & numerous steroid injections I finally found ONS & Dr Delos. I WISH I had found him earlier! He listened to my story, understood MY situation & MY needs, evaluated MY condition & found a solution. He presented options & explained them all thoroughly. We made the decision together to undergo a partial knee replacement & WOW what a difference. At 7 months I walked a half marathon with NO ill effect, & I am back bike riding and hiking. And did I mention that this was an opioid free surgery – I did not need ANY strong painkillers – even in the hospital, I felt very little pain at all, I was only taking Tylenol!!! And as for the scar on my knee – what scar – you can barely see it! Thank you ONS and Dr Delos. (5 Star Review on Google from G.W.)

Dr. Delos performed ACL repair surgery as well as a meniscus repair after a ski accident in March 2018. Dr. Delos is not only an excellent surgeon, but also a caring and concerned doctor. I highly recommend him to anyone considering any type of knee surgery. I am almost back to my full strength and am forever grateful to Dr. Delos and the Physical Therapy team at ONS. (5 Star review on Healthgrades from M.R. in Riverside, CT)

Dr. Delos is an outstanding man, doctor, and friend. He helped save my leg and got me back on the field way quicker than anyone expected. Would recommend him to anyone who is looking for an orthopedic surgeon in Fairfield County, CT. One of the best around. (5 Star review on Healthgrades from P.)

Dr. Delos diagnosed my torn ACL and suggested reconstructive surgery using a part of my hamstring. I was reluctant to commit to surgery because of friends who had horror stories (with doctors in different practices), however Dr. Delos talked me off the ledge several times, boosting my confidence. Everything went seamlessly and his bedside manner both before and after the surgery was extraordinary. I couldn’t recommend him and the ONS team enough! (5 sSar review on Healthgrades from S.O. in Stamford, CT)

I was very pleased with the surgery Dr. Delos performed on my knee. I did not feel much pain at all after the surgery. I was walking normally in less than a week after my surgery. Dr. Delos was also very accommodating in that he used my MRI report from another center and didn’t make me do a new one, which saved me a lot of time. The office staff was also very good with all the follow ups and setting up appointments. Highly recommend Dr. Delos for knee arthroscopy(5 Star review on Healthgrades by R.J.)

Dr. Delos was very helpful in determining expectations on the recovery time and reassuring that the whole process would go without a hitch. (5 Star review on Healthgrades from S.B. in Old Greenwich, CT)

Overall – very pleased. Great bedside manner and professional. Great surgeon and follow up post-surgery. Always available when needed as well as attention to detail. Listens to concerns and needs. Have recommended to friends and would go back. The staff at ONS was amazing also. (5 Star Review on Healthgrades from S.A.)

In a little less than two years ago, I had a small accident and broke my right shoulder. I had been seeing another physician for almost five months and my shoulder still wasn’t healing. The physician had tried of number of different things but nothing seemed to help. Needless to say my frustration level was over the top. Being right handed, many things in my life were quite difficult especially since my job requires me to type a lot on a computer.  I had just seen the physician for an appointment and he wanted to wait a few more weeks to see if what we had been trying for months might finally work to get my bone to heal. A member of my family convinced me to see a doctor in the ONS practice because they had helped him a few years earlier. I made an appointment for Friday, July 29 with Dr. Delos. I met with him and conveyed my overwhelming frustration and I needed something done quickly. After reviewing my case and seeing the other things that had been tried, he realized surgery was the only option left. I agreed but told him it needed to be done as soon as possible because in six weeks I was going away and needed to be well on the way to being healed by then. Well, he and the staff took my request very seriously and started jumping through hoops to get me in for surgery. The staff was very helpful in getting everything together. Everything about the surgery was explained so I understood the procedure and recovery very well. Well, five days later on Wednesday, August 3, I was in Greenwich Hospital getting my surgery. The surgery was a total success. All my follow ups went well and the staff took great care of me. I would easily recommend ONS for any orthopaedic needs, big and small. Thank you. I can’t explain how good it was to get back the use of my arm.  (F.V.O, 5 star review on the ONS Facebook page)

I had a bilateral knee replacement in May of this year and I could not be more pleased. While there was some concern about doing both knees at the same time, the procedure went extremely well and the recovery has been all I could have hoped for. I would highly recommend Dr. Delos for this procedure. If possible, he exceeded my expectations.  (5 star review on Healthgrades from a patient in Stamford, CT)

Dr. Delos is a wonderfully gifted orthopedic surgeon who is also incredibly compassionate and personable. He instills a well-deserved sense of confidence in his patients, and even has a sense of humor! Dr. Delos surgically repaired my fractured collarbone by affixing a metal plate. The fractured bone and surgical wound healed completely without complication and post-surgery pain was well-controlled and never an issue. I highly recommend Dr. Delos and the highly efficient staff at ONS. (Five star review on Healthgrades from a patient in Port Chester, NY)

Dr. Delos recently performed arthroscopic knee surgery for a torn meniscus. I was pleased by his conservative approach to addressing my injury with a plan I was comfortable with. I started with Physical Therapy first, and then ultimately surgery. He thoroughly explained what the surgery would entail, the recovery process and set a realistic expectation of when I could return back to exercising. (Five star review on Healthgrades from M. in CT)

Dr. Delos is an awesome surgeon. He performed a knee replacement for my husband. Could not have had a better surgeon. Dr. Delos also helped our daughter who was injured in Canada with a fractured hip. His approach to her was so positive, and he was extremely honest with her prognosis as long as she followed his direction. She is now doing full marathons and an Ironman. All of this was because of Dr. Delos. He is the best surgeon I have ever met. His people skills are beyond reproach as well as his office staff. (Comment from Rate MDs)

I broke my shoulder and arm and Dr. Delos was brought in to operate on me. He’s got a wonderful manner about him and he’s an excellent doctor who follows up with his patients. (comment from Health Grades)

Dr. Delos is a very competent and caring surgeon, who is respectful of his patients as well as their time. He is knowledgeable and capable as well as kind. He operated on my broken ankle and I had an excellent results. (comment from Health Grades)

If it wasn’t for Dr. Delos I would not be walking without pain. I am almost 7 months out from TKR and I feel great!!! I am back to my normal routine. Dr. Delos’s bed side manner is fabulous. He is caring and listens to what you have to say. I recommend him all the time when people ask who did my surgery. (comment from Health Grades)

I broke my knee cap in 7 pieces. Dr. Delos repaired my knee with such expertise that I have healed quicker than expected. His professionalism is excellent and I would recommend him to my family and friends. (comment from RateMD)

Dr. Delos is not only an exceptional doctor, but he is caring and compassionate. My daughter had a torn ACL and Meniscus and was scheduled to compete in Disney. Dr. Delos worked with her to assure she could take the mat and compete prior to her surgery. He was factual but understanding of the opportunity she had in going to Disney. I would recommend him to EVERYONE in need of his specialty. (comment from RateMD) 

Young, innovative, and on the cutting edge of his specialty. Dr. Delos replaced both my knees and I had wonderful results with minor pain, minimized by his phenomenal anesthesia formula. Best of all, the lack of external stitching (using medical glue instead) eased the healing process and left no ugly scarring. I could not ask for better results. Highly recommended by HSS and deservedly so. Thanks Dr. Delos. (comment from RateMD)

Dr. Delos and the entire staff at ONS are and always have been so friendly and professional. I cannot say enough positive things about him and will gladly recommend him and ONS to any and every one! Thank you all so much! (D.P.)

Dr. Delos has been an excellent physician throughout. I always felt like we were in this together. (Patient Survey)

I’ve had my share of experiences with orthopedic surgeons. But I must say Dr. Delos is by far one of the best if not the best doctor I’ve ever been to. He strives to do the best for you and your recovery. Thank you for all of your help Doc because of you I can go back to my normal life. God bless you this and every day. (R.M.)

For 21 year old S.R. the first game of the Division III  soccer season at SUNY Purchase was her last.  She twisted her knee awkwardly while running down the field and tore the anterior cruciate ligament (ACL) in her knee. She knew the ordeal she was in for, having torn the ACL in her other knee four years earlier while playing high school soccer.  “I knew there would be surgery and six months of rehabilitation, but  it was my senior year and I was determined to be back in shape to play lacrosse in the spring,” she said.

With the help and guidance of sports medicine specialist, Dr. Demetris Delos, S.R. achieved her goal.  Not only did S.R. contribute to her team’s 9 and 3 season, she was named MVP of the team, and Female Athlete of the Year by the university. She also qualified for the First Team All Conference and All Regional in lacrosse.

“Dr. Delos was so nice and friendly and straightforward in terms of expectations and recovery time. He turned a bad situation into a great experience.”  (S.R.)

Sam McCanncropp

12 year old soccer player, Sam M., was on top of his sport when he developed knee pain and swelling after a fall during a game last June. He kept it to himself because he didn’t want to jeopardize his chance to compete internationally at the Madrid Cup in September.  Although he did make it to the tournament,  he spent most of his time on the sidelines with his knee too painful, swollen, and difficult to move.

Upon returning home, Sam’s mother, Paula, brought him to see Dr. Demetris Delos, a sports medicine physician who specializes in knee injuries.  Dr. Delos ordered an MRI, which revealed a slight fracture in Sam’s knee and a one inch piece of loose cartilage that would require surgery to repair.  The injury was close to the growth plate, which could have had long term consequences.  However, the surgery went well and Sam is back on the soccer field with his sights on the Hackley School’s Academy Team.

“Dr. Delos was always positive and everything he said would happen transpired, “said Paula M., Sam’s mother. “I was very impressed with the high level of care and collaboration with the physical therapists because they all wanted Sam to achieve his goal.  Everyone was unbelievably caring.” (S.M.)

When my arthritis got so bad that I couldn’t walk, I knew I needed to have my right knee replaced. I went to ONS because my daughter had been treated by Dr. Camel and Dr. Sahler, and I was very impressed by how supportive and caring they were. As soon as I met Dr. Delos,  I had every confidence that I was in good hands. He has a great bedside manner, he’s honest and straightforward. He took the time to answer every question my husband and I had about the procedure. Two months after my surgery, I was able to take a trip to Cancun and walk around the Mayan ruins and the only thing that bothered me was the heat.  I’m going to Disney World next month, and I can’t thank Dr. Delos for making it all possible. I recommend ONS to everyone.  (S.S.)

In July  of 2014, Dr. Delos performed ACL surgery on my daughter.  Brooke is doing great!  In fact, since surgery Brooke has returned to playing volleyball & basketball.  She played Varsity Volleyball from Stamford HS where she was a setter.  She also played Varsity Basketball where she was the starting point guard.  Both teams had a great year, but the girls basketball team had a historical year. The Stamford Knights won the FCIAC Title (District title) and the CIAC Title (State Championship.)  Thanks to Dr. Delos, Brooke was a huge part of the team’s success. (C.K.)

I came home from my vacation in the Dominican Republic with two broken shoulders. Dr. Delos was absolutely amazing. He has a kind and caring bedside manner and when he told me I needed surgery on my left shoulder, I never had a thought to go anywhere else. I highly recommend him. (J.R.)

In 2014, local student athlete Brooke was playing basketball with her team in the 7th of 8 games at the AAU Nationals when she became injured during a layup after another player collided with her causing immediate knee pain. “I fell down and the trainer helped me off the court. We could see instant swelling and knew I needed to see a doctor” said Brooke.

Brooke suffered a painful injury which required surgery. ONS orthopedic surgeon Demetris Delos, MD performed surgery to repair a torn ACL and a partial meniscus tear. Brooke said, “I felt a little bit timid before the surgery but the surgery went well.” (more…)

Dr. Delos operated on my broken ankle 6 months ago and today I have graduated and am doing great! My experience was very good at ONS and I have a healthcare background so I am very picky when I choose a doctor. The ONS office is extremely well-run and the ambulatory care center is top notch. I’m not sure how they could do a better job and they called me the next day to see how I was doing after surgery. I’ve referred friends to ONS in the past months that have seen other specialists at ONS who have told me they have all had the same experience. I’ve even brought my daughter here for care. Dr. Delos is very knowledgeable, competent, and caring. (M.S.)

I had a full tissue tear of my rotator cuff. Dr. Delos examined me and pointed out the alternatives and how we could approach the injury. He explained his plan and operated to repair the damage at the ambulatory center. The experience was very good and they called me the next day to see how I was doing.

I needed physical therapy 3 days a week for the first few weeks, then twice a week and now I so much better six months later. (more…)

ONS is excellent! The staff is warm and very nice to children. I injured myself at work and came to see Dr. Delos. He explained that I needed surgery and it was scheduled at the Holly Hill Ambulatory Center. ONS and surgery center staff are lovely people. Dr. Delos was very human and made sure to explain all that I needed to have done to get back to normal. It was a perfect experience and I am pain free. (I.K.)

Dr. Delos, – “I was new customer at ONS. The staff showed me that they are really professional and made me feel comfortable, that they were reliable and it felt like home. Thanks everybody!” (Anonymous)

Everyone at ONS was very warm and friendly. Dr. Delos was extremely helpful and very direct with his thoughts and recommendations, which I liked! (Anonymous)

Dr. Delos was incredibly helpful and knowledgeable. He diagnosed my son’s Lyme disease almost immediately and this was confirmed by testing. (Anonymous)

Testimonials

From the moment I walked in the ONS door with my broken right patella, I knew I was in the right place!  I was most fortunate to be referred to Dr. Vadasdi by two of her former patients. I immediately felt comfortable as she is an Ironwoman Triathlete and I am a 3 time Ironman.

The entire ONS group, from surgery to PT, has turned a most difficult situation into a pleasant one.  I am always greeted with a warm smile and never wait more than five minutes.  The staff at ONS took care of ALL my health insurance needs leaving me with my sole responsibility of showing up on time. I would highly recommend ONS to anyone in need of orthopedic care or PT. They are simply the best. This is from the heart as I am soooo grateful for ONS taking good care of me!! (patient S.W.)

Dr. Vadasdi was wonderful. She performed two surgeries, the first to find out what was wrong with a repair conducted by another surgeon, and a second to then fix the problem. She also thought to collect tissue samples during her first surgery, then finding that I had an infection that required 6 weeks of daily antibiotic infusion. I am now 100% healthy and back to normal routines, including yoga (at age 68!) (comment from RateMD)

My experience was fantastic! Dr. Vadasdi was incredible. She did a great job on my shoulder. I strongly recommend that anyone who is facing shoulder surgery to use Dr. Vadasdi.

I have had shoulder surgery before and Dr. Vadasdi is the best and so is the ONS staff! (Patient Review)

I find Dr. Vadasdi to be a genius and compassionate doctor. Her care of me as her patient was outstanding! (Patient Survey)

I have been coming here for at least 15 years and have seen a variety of amazing doctors … Dr. Greene being a favorite in our household for years and would trust him with everything.  Recently I broke my elbow and was sent to Dr. Vadasdi.  She was amazing! Great with surgery and aftercare. Very compassionate throughout the whole process! Thank you ONS for getting me through everything! (E.D.)

Dr. Vadasdi: It’s been over a year now since my elbow surgery and I’m back in full swing. Literally! My golf swing- I had my best season to date (over 45 rounds) and achieved my lowest handicap score of 10.8. I can’t thank you enough for applying your surgical skills in repairing my elbow. With PT my recovery was smooth and quick. I was back up and running in just a few months. I feel better and stronger than ever. Your staff from start to finish was professional and compassionate. Thank you. (D.T.)

 

Dear Dr. VadasdiI neglected to tell you today how much I appreciated the excellent rebuild of my shoulder.  You are obviously very talented as my recovery demonstrates. I recommend you to everyone! Thanks again for your time, concern, and operating skills. Have a great New Year!  (CS)
