Testimonials

Dr. Berliner was great with our son! He was kind, professional, and put our minds at ease. We are so grateful he was the doctor that came to fix our son’s wrist! I would highly recommend Dr. Berliner!  (5 Star Review on Healthgrades)

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

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 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

From realizing it was time for a knee replacement to researching a knee replacement doctor, a friend spoke to me about Dr. Choo from ONS. When I saw that he took my insurance it was a go. I paid close attention to the team Dr. Choo has. They are so informative and caring. I had such help from them setting into place what help I would need at home. Dr. Choo was so confident in letting me know what a better quality of life I would have. It has been 5 months since the surgery. Dr. Choo gave me the confidence to endure the icing of the knee and the exercising is so important rest and fluids. To stay focused on the healing process. Thank you Dr. Choo and his team. God bless you all. (5 Star Review on Healthgrades from DS)

Knowledgeable, professional and caring. Thoroughly explained my condition to me. (5 Star Review on Healthgrades)

The office seemed very clean and well run, everyone was nice, Dr Choo explained everything clearly, was friendly, and I left feeling confident in what needed to be done. (5 Star Review on Healthgrades)

Dr Choo employs the anterior method of performing hip replacements and, two weeks after my procedure, I am very pleased indeed to give him the highest possible rating. It’s relevant to note that I am 86 years old. My experience has been remarkable. The very same day of my operation, the nurses and therapist at Greenwich Hospital got me on my feet with a walker and I was able to walk down a corridor. Courtesy of Dr Choo’s skill, plus no doubt the effect of blockers, recommended medications and occasional ice – packs, my recovery has been almost pain-free. Dr Choo exhibits a highly confident and pleasant and professional manner – entirely justified in my experience. (5 Star Review on Google from DM)
I, too, am two weeks into a full hip replacement performed by the amazing Dr. Choo who was absolutely perfect!! His explanations, patience, humility, respect, and most importantly his immense skill and knowledge in this area were exactly what I needed to get through this hip replacement, following the multiple spinal fusions I’ve also had at ONS. He collaborated with my spine surgeon early on and set a course that was perfect in planning and execution. I couldn’t be happier or recommend Dr. Choo more highly — he is fantastic in every way. (5 Star Review on Healthgrades from P.K.)
I am two weeks into a full hip replacement. Dr. Choo could not have been better. He explained all procedures clearly and thoroughly, used a front entry incision, and a spinal and a sedative instead of full anesthesia so I recovered quickly after the surgery. Dr. Choo invited questions on my part and listened and answered all of them in terms I could understand. After the surgery he checked on me three times in the hospital and called me at home the day after to check on me. Everybody associated with ONS was helpful and caring. All appointments were made quickly and were not rushed. I am not medically knowledgeable – but I did due diligence looking into the details of full hip replacement. Dr. Choo is state-of-the-art in his work, and a kind and caring professional. I can recommend him with the highest possible rating.  (5 Star Review on Healthgrades from M.G.)

Excellent-responsive and interested. (5 Star Review on Healthgrades)

My 83 year old mother-in-law fell in April and broke her hip which required emergency surgery. This was made even more tragic since it was during the height of Covid-19. Dr.Choo, who we could only meet by phone, was extremely kind, compassionate and professional. He addressed all of our questions and concerns and really put our family at ease during this difficult time. At our request and without hesitation, Dr. Choo called a friend of ours, a surgeon at HSS, to go over the case prior to surgery. I don’t know many doctors who would have agreed to do that. The surgery went extremely well and I am happy to report that my mother-in-law is doing fabulous! Thank you Dr. Choo!

I waited three years in pain and at the end of 2019 I was in so much pain that I was dragging my right leg, the pain was incredible. I went to see Dr. Choo, he made me feel that he can give me my life back and he did. I suffered for 3 years because I was afraid. Today I’m so happy. On valentine’s day 2020, I got a new hip and the surgery was great, the pain management was great and I didn’t end up needing extra strong medicine. I was determined to get better and I was walking right after surgery. Thank you to Dr Choo and all his collegues, I have my life back and I can do anything I want with no pain. (5 Star Review on Healthgrades from G.I.))

I knew I probably needed a total hip replacement for several years, but I was terrified.
After a trip to the ER when attempting to ride my bike, I realized it was time. I was very impressed with Dr. Choo’s credentials and once I met him, I knew I had the surgeon I needed. He explained the procedure and what to expect really well, and that so helped to put me at ease. Dr Choo and his team are incredible. I am six months post -op and I can’t believe how great I feel. Thank you, Dr. Choo! (5 Star Review on Google)

If it were possible, I would give Dr. Choo 6 stars. My emergency broken hip surgery was perfectly executed by Dr Choo. He was a gift to me from heaven. His kindness, understanding, professionalism/knowledge and skill was the perfect package. I’m very grateful he was on call for my accident. (5 Star Review on Healthgrades from M.S.)

Testimonials

I am a Director of Critical Care and a seasoned RN as well. Dr. Green is top notch- I send everyone to him that I can. He is humane, highly comprehensible, takes his time, explains things well and is clinically excellent! The surgery center he uses in Stamford was excellent, clean, great staff and everyone was in the same page! (5 Star Review on Google from L.J-K.)
I can’t say enough positive things about Dr. Greene. I am a professional tennis player and had a literal and figurative pain in the butt when I played. Other symptoms included recurrent groin “pulls” and glute strains and deep achy pain across my low back. No one could properly diagnose the underlying cause until I saw Dr. Greene, who diagnosed me with labral tears and impingement (FAI) in both hips. My symptoms did not perfectly align with those typical of FAI, but he believed this to be the cause and we decided it was best to operate given my urgency to get back to the tour. He basically did a rim trim, osteoplasty and labral repair on both sides (6 weeks apart). This decision had me so anxious, and now I sit here 3.5 months after my second hip surgery, Indian-style… sorry, it’s 2020… “cross-legged” with no pain whatsoever! I am back to playing tennis and weight training – already doing things I previously could not. I couldn’t be happier with my decision to use Dr. Greene over other prominent surgeons in NYC and CT. He is by far the most trustworthy, communicative, personable (and probably most skilled) of the four surgeons I saw… he also has a great sense of humor, despite being a Falcons fan. (5 Star Review on Google from S.K.)

I thought it was important to send a note to someone at ONS about Dr. Greene and Alicia Hirscht, DPT. I have been treating with Dr. Greene for a torn abductor tendon and other hip issues since December. I started PT in Stamford under Alicia Hirscht. I would easily recommend either practitioner to a family member.

Dr. Greene’s communication was clear and concise when weighing treatment options.  PT Hirscht made room in her schedule for me and took the time and effort to get me up and playing tennis again. They are both true professionals and showed an incredible amount of patience working with me to recover from my chronic injuries.

Keep up the excellent work and hiring practices. (note from patient P.Y.)

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.)

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. (5 Star Review from Google from P.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! (E.D.)

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. (T.A.)

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. – (R.G.)

 

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. Greene (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! – (L.A.)
