Dr. Canton is one of the best doctors I have ever had! Definitely recommend for any hand/arm problem. Pleasure to deal with … (5 Star Review on Google from C.C.)
Best doctor ever! Dr Cantlon fit me in same day and despite the fact that I knew he was busy, I did not feel one bit rushed. He listened to me intently, explained everything in detail and even went through each xray one by one. I couldn’t recommend him more highly!(5 Star Review on Healthgrades)
We cannot thank Dr.Cantlon enough for his care and expertise in helping our young son recover from a broken arm. From the moment he came to the ER to set the bones, to the 3 cast changes and the appointments along the way he was reassuring, attentive, calm and we felt like we were in the best hands. The ONS front desk staff, nurses and Xray tech were also so kind each and every time ….even when my son would cry from fear. I highly recommend ONS and Dr.Cantlon. We are so grateful our son healed so well and it back to running around! (5 Star Review on Google from C. G.)
A careful, thoughtful doctor, whose excellent treatment skills are matched by his empathetic manner. Though still young, he possesses the clinical knowledge to treat the body, and the emotional knowledge to treat the patient as a whole. (5 Star Review on Google)
Today was my 1st visit to see Dr. Cantlon and he has such a great bedside manor, he’s gentle soft spoken, and easy on the eye lol. In all seriousness I really appreciate him and his staff taking such great care of me, and let me add no wait time which is very important to those of us who work. (5 Star Review on Healthgrades from D.M.)
Dr. Cantlon was terrific. He spent time with me, asking me questions, clarifying info and asking me if I understood. Got additional Xrays (tech was great too) which showed no break. So I was happy. Very happy.
Hopefully I don’t have to go back, but Greenwich ONS (Orthopaedic and Neurosurgery Specialists), the staff, and Dr. Cantlon (Hand and Upper Extremity Surgeon) were great. Highly recommended. (Five star review on Google)
Dr. Cantlon is very smart and is so nice. I would definitely go back and recommend. (Patient Survey)
Dr. Cantlon has been great. During our Greenwich Hospital ER visit for a pediatric broken thumb and the ONS follow-up visit, his efficiency, clarity, and bedside manner he had for me and my 11 year old was excellent! (Patient Survey)

Excellent experience with both Dr. Heftler and his staff. Thank you! (5 Star Review on Google from KH)
Unbelievable experience after many years and many doctors and feeling incredibly defeated I randomly saw ads for this place and figured what do I have to loose. After one visit, Dr Heftler figured it out. By this point I’d already had 6 MRIs from other doctors, medications, injections to no avail. He called me with the news himself not a nurse. I couldn’t be more impressed and grateful. I couldn’t be more grateful to him after years of debilitating pain someone finally figured it out. He then referred me to Dr Greene for surgery, another fantastic experience. All in all I will ONLY ago here for any orthopedic needs and send everyone else here. PT employees are fabulous, nurses and desk staff always made a pleasant experience. Highly recommend. (5 Star Review on Yelp from E.C.)
I have living with chronic pain for years from a 14 year-old injury … I didn’t realize how used to it I had gotten. For the last 2 1/2 years, the pain became debilitating and I’ve gone to SO MANY doctors with no answers or guidance except physical therapy and meds and stretching! CLEARLY this wasn’t helping. One day I saw an ad for ONS on TV, then a billboard on the highway and decided it was worth one more try. While they didn’t have insurance compatibility yet in Harrison which is more convenient for me … they did in Greenwich and I went to see Dr. Heftler. I ran a couple minutes late and was stressing because usually doctors’ offices are so rude when you run late ….. but she couldn’t have been more patient, understanding and put me at ease. At my first visit, Dr. Heftler was super helpful and asked me questions no other doctors had. He prescribed something no one else had that helped to slowly reduce the pain. I’ve had 5 MRIs and not one doctor asked if I had had one with contrast until Dr. Heftler. I then had one with contrast and he found the problem. Now onto the next steps. I couldn’t be more relieved, grateful, validated and appreciative. Thank you so much for thinking outside the box to figure it out. You have no idea what you did for me. I will recommend this establishment to everyone I know … (5 star review on Google written by E.C.)
Dr. Heftler has an excellent bedside manner and takes his time with you. I was just in for an epidural injection for a bad herniation of my L5-S1 and he provided me with the time I needed, to be certain all of my questions were answered. On the day of the procedure, the doctor was extremely pleasant and kept my mind calm with plenty of fun conversation. My fingers are crossed that I get some relief from the injection, but hands down he is highly recommended and I won’t go anywhere else. (comment from Health Grades)
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)
Dr. Heftler is wonderful. He shows exceptional bedside manner and spends plenty of time with each patient. My back issues have placed a lot of strain on me, and it has been comforting to have a doctor like him work with me using non-surgical treatments. Highly recommended. (Patient Survey)
My experience with the entire ONS practice is nothing short of exceptional. The doctors are beyond caring and are professional and respectful of my time which is almost unheard of these days. I recommend your facility for both Dr. Heftler and Dr. Sethi to anyone wanting fantastic quality and care. (Patient Survey)
Dr. Heftler is my angel! He is simply the best!! (Patient Survey)
“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.” (E.H.)
L.S. of Greenwich is an athletic 51-year-old mother of two, who has enjoyed sailing, skiing, golf and other sports over the course of her life. Two years ago she developed painful tendinitis in her left elbow. Her elbow became so painful that even picking up a glass of water was excruciating. The following June, Dr. Seth Miller gave her a cortisone injection into the joint which brought her initial relief. Unfortunately, the benefit wore off after about eight weeks. When she returned to Dr. Miller, he suggested she try a new treatment option called PRP (Platelet Rich Plasma). Although not FDA approved, the treatment is increasingly being used by orthopedic surgeons and physiatrists to treat soft tissue problems such as tennis elbow, hamstring strains, MCL strains and patellar tendonitis. At ONS, PRP is administered by physiatrist Dr. Jeffery Heftler, who explained the procedure, “First, 10 milliliters of blood was drawn from Lynn’s arm and then spun in a centrifuge for five minutes. This separates out the platelets from the rest of the blood. Then two to four milliliters of the separated blood is drawn out and injected it back into the injury site.” The theory behind the treatment is the platelets release growth factors which stimulate a healing response. Unlike a steroid injection, it can take up to six weeks to notice the full benefit of the injection. However, PRP seems to be effective in cases where steroids have failed. L.S. was instructed not to use her arm for anything strenuous for two weeks but by the third week, she could tell it was feeling better. She started physical therapy to help get back the strength in her arm and by three months she was entirely pain free. L.S. says, “I am a big fan of PRP. I am now free of pain and back to doing all my normal activities.”

Great visit. I came in because of pain in my upper back/neck. Dr. Sahler was friendly and concerned and spent time asking me questions about my sports activity and lifestyle. After having me x-rayed, he was really great about showing me the x-rays on his laptop and clearly walking me through what the issue was (it was ligament-related in my neck…a sprain). It was also good that he showed me what was healthy + good about my spine too. We then talked about simple lifestyle changes. (5 Star Review on Healthgrades)
Doctor is a good listener, thorough regarding review my case and explained treatment & follow up very professionally.(5 Star Review on Healthgrades from Dr. H in Redding, CT)
Dr. Sahler is very compassionate, listens to you, works with you to plan treatment. (5 star review on Healthgrades from P.B. in Wilton, CT)
Dr. Sahler has provided exceptionally good care taking patience and gave a long view in tracking down and treating residual pain after back surgery. He provided as much art and detective work as traditional medicine. I am grateful that he has stayed with the chosen course because with each treatment, the pain is less and I become closer to getting my old life back. (Patient Survey)
Dr. Sahler was very knowledgeable and helpful!!! (Patient Survey)
Dr. Sahler is incredible! I was in a ton of pain and it felt like I was being stabbed in my back every time I got out of the car and up from my desk. I had fluoroscopic lumbar spin injections at the new surgery center and felt immediate relief during the procedure. I had full relief within a few days!!! ONS has a great group of doctors and a wonderful support staff!!! I proudly and gladly call the the doctors at ONS MY Doctors!!! RV-C (Facebook)
I want to thank Dr. Sahler for the tremendous job he did giving my daughter an injection and taking the time and effort to have a heart to heart talk with her. In my experience, most doctors wouldn’t take the time to do that, usually next in line is right at the door. She really had a connection with him and I wanted to make sure all of the time that he gave us was very much appreciated. (D.S.)
Arthritis had taken its toll on my shoulders. I was in constant pain. Sleeping was difficult and the activities I love, like kayaking, were difficult. Two friends with similar shoulder issues referred me to Dr. Miller at ONS. When I met him, I immediately knew he was the doctor I wanted to care for me. He was thorough, thoughtful and patient. He has a great bedside manner and took the time to completely answer all my questions. Continue reading “Dr. Miller: Shoulder Replacement”→
