Testimonials

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 Dana S-B)

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 Matt F. of Danbury, 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 Pam P. in Norwalk)

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 Lisa in New Canaan, CT)

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. (Laura D.)

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.  (JB, 5 Star Reveiw on ONS Facebook page)

Testimonials

Dr. Cunningham: After coming from a less than adequate experience from another practitioner and staff, I was truly amazed and pleasantly surprised at the professionalism and courtesy of your office extended to me as a new patient. From receptionist to doctor, I enjoyed my experience! Thank you!! (Patient Survey)

ONS has some of the best physicians and Dr. Cunningham is one of the best! (Patient Review)

This is the best medical practice I have ever experienced. Dr. Cunningham was terrific and I cannot say enough good things about him. He has a great staff and it is very much appreciated. (Patient Survey)

Cos Cob resident J.M. was 24 when he was playing basketball with friends and tore his ACL. An x-ray at Stamford Hospital indicated no broken bones but Jason was advised to see an orthopedist. The next day, he visited James Cunningham, MD. A physical examination determined he had most likely ruptured his ACL. An MRI confirmed the diagnosis. “An avid basketball player and all-round athlete, J.M. was a good candidate for an ACL reconstruction,” said Dr. Cunningham who, in the surgery last April, used part of his patient’s patellar tendon to reconstruct the ACL. The surgery also included work on a partially torn meniscus. The surgery lasted an hour and a half and J.M. went home later the same day. His recovery was steady and his pain was managed with Advil. After five days he began a physical therapy program, which he followed three days a week for the first month and gradually reduced over the following few months. His knee regained full flexibility and before long he returned to playing basketball with his friends. (JM)

Dr. Cunningham has been my doctor for many years and has done a successful meniscus repair 6-7 years ago. More recently he helped me with a stiff shoulder 3 years ago, (advising excellent stretching exercises that worked) and has been very helpful with my knee and ankle problem. On my latest visit he was very effective in assessing the problem with my knee by recommending and administering a cortisone shot (which had excellent results) and laying out a plan for the next six months so I can return to golf. As I age he is an important medical partner. (FB)

Testimonials

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. (RM)

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

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! (DP)

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 Sara A.)

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 Sasha B. in Old Greenwich, 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 Patrick)

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. I would recommend him to EVERYONE in need of his specialty. (comment from RateMD) 

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 Stacey O. in Stamford, CT)

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. (CK)

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 specialists, 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.”  (SR)

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)

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)

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. (JR)

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)

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)

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 Rakshiet J.)

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.  (SS)

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 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)

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.” (SM)

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 Michele R. in Riverside, CT)

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 Gail W.)

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)

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)

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 Margaret in CT)

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)

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. (MS)

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. (IK)

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

Just took my daughter to an appointment with Dr. Tim Greene after a disappointing appointment at another orthopedic office not affiliated with ONS. If I was able to…I would give Dr. Greene and ONS a rating much higher than 5 Stars.

I could not have been more impressed with every aspect of my daughters care. The offices were clean & the staff was extremely welcoming & friendly. We were brought into the exam room early which in most cases doesn’t happen at a doctors office.

Dr. Greene came in and listened to our concerns/issues, examined our daughter and was in absolutely no rush to move on to his next patient. He answered all of our questions, explained the X-Rays to us and expressed genuine care for her injury and treatment. He made sure we understood everything and had a plan going forward.

We also had concerns about how to schedule MRI’s and other testing. He immediately sent a note to someone on his team to help us. We sat with Jessica who took her time and made all the arrangements for us. She also followed up the next day with info we needed to make sure everything was done right.

About 3 hours after our appt. with Dr. Greene my wife and I had a question we forgot to ask. We called the office after Dr. Greene had left but a message was taken and I was assured either Dr. Greene or his assistant would call back the next day. They called in the morning and answered everything for us.

Being an athlete and also a firefighter I have seen a lot of orthopedic surgeons and have been to many practices and I can say this was one of the best experiences I have had. In my opinion they go way above the standard of care. I would highly recommend Dr. Greene to anyone who may need orthopedic care. (Five star review from Google from patient Paul F.)

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! (ED)

The ONS team is like family. Dr.Greene is my hip doctor and he is excellent!! I feel that I am in great hands from the moment I walk in the doors.. Thank you ONS. (TA)

Doctors, Nurses, Therapists, and support staff: This is a big THANK YOU for all the expert and attentive care you extended towards my recovery from a broken pelvis and elbow after a spill on black ice in December ’09. Let everyone know, there is Zumba after broken bones heal. I received excellent care at Greenwich Hospital, with elbow surgery by Dr. Geene (yay for titanium). Each of you as a part of this “total team” took me from being in excruciating pain and bedridden to no pain and full function and then some! – (LA)

 

Dr. Greene: It has been 6 weeks since you mended my fractured left clavicle and I continue to make progress in my recovery. I estimate that my range of motion in the shoulder is close to 90% and I am beginning to cautiously build strength in the muscles affected by my injury. I wish you a wonderful Thanksgiving, and this year I am especially grateful for having such a great orthopedist as you. – (RG)

Testimonials

I was injured in my military career and for 29 years, have managed through neck and spine pain that was caused from it. It became unbearable with numbness in my fingers and inability to sleep, sit or work. I have never had nerve pain like I did and when I saw Dr. Nocek, he sent me for an X-ray then MRI to determine what was happening. While waiting for results, he sent me to physical therapy and to Dr. Heftler, a physiatrist, for an injection to help relieve the symptoms until we could determine what to do. Bottom line, I needed spine surgery. I saw ONS neurosurgeon Dr. Fiore, who got me right into surgery, repaired 3 discs, and cleaned up the problems. Immediately, and that’s no joke, immediately, I could tell I was on the mend. I’ve had chronic pain for 29 years and now, almost three months out, the constant ache and nerve pain isn’t there. I had lost feeling in part of my had and fingers which has since returned. Best part of my ONS experience was that everything is onsite and getting to the bottom of this just took a few short days. Everyone works like a team. They are specialists, unlike my experience at the VA. Meanwhile, they helped me manage the pain. I have never experienced this before and I’m very pleased with the results. If you need a neurosurgeon, specialized orthopedist, physiatrist or physical therapy, I totally recommend ONS. ( RateMD)

“Having recently completed four months of treatment at ONS, I wanted to share my positive experience as too many times this recognition may not be communicated.  Suffering from an old injury of a herniated disc, David Nocek, MD determined it had developed into sciatica.  Early physical therapy sessions with Fey Adamarola, DPT, had temporary relief,  so I was referred to Jeffrey Heftler, MD to get my pain to lower levels to pave the way for an aggressive PT regimen.  It was Fey’s positive outlook that gave me the confidence to stay the course and lead to a very positive outcome. I am grateful to the full team at ONS.” (EH)

Testimonials

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! (ED)

Dr. Vadasdi– I was given great information prior to and post surgery. The staff and Dr. Vadasdi were very responsive.  I was very pleased with all aspects of the experience. (Anonymous)

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. (DT)

 

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

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

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)

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)

 

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.
