Review of Dr. Kowalsky

- |

Dr. Kowalsky is not only a terrific surgeon, he is a very thorough doctor who takes time to explain the procedure in detail until the patient is both knowledgeable and comfortable. I highly recommend Dr. Marc Kowalsky. You won't be disappointed! Fred Camillo Old Greenwich, CT

Review of Dr. Berliner

- in DARIEN , CT |

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.

Dr. Delos is a 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.

Review of Dr. Sethi

- in Westport, CT |

What an all star! I had a lot of shoulder trauma in my youth requiring 4 extensive surgeries in the 80s and 90s. All of these repairs led me to a serious arthritic situation requiring me to have a total shoulder replacement in my 50s. After careful review, I selected Paul Sethi at ONS. A great choice! The operation took place in their Stamford medical suite so no risk from all of those infectious transmissions that can show up in the hospital. Paul was extremely thorough in his diagnostic prep and model building leading to a very smooth procedure. What blew me away was that I NEVER had any pain after the operation! My rehab was smooth and my therapist says he has never seen such a phenomenal total shoulder replacement in terms of range of motion, fast recovery and overall strength. The frequent office follow ups were reassuring and conservative. I could not be happier and recommend Dr. Sethi wholeheartedly!!! This guy is a winner.

Review of Dr. Kowalsky

- |

After receiving no relief from a major NYC Ortho hospital for a severe case of tennis elbow, I found Dr. Kowalsky. He assured me that even at my age, 66, there was no reason that my tennis days had to be behind me. He performed surgery flawlessly, and I was back on the tennis court in 3 months, playing some of the best tennis I have played in years. I will be eternally grateful to him for not putting me out to pasture and I will continue to recommend him to others. He is kind, caring and an excellent surgeon. Simply the best!

Review of Dr. Kavanagh

- |

Dr. Kavanagh is an amazing doctor and a great example of really caring about his patients. I had a hip replaced in February 2019 and a knee replaced in June 2019. With Dr. Kavanagh's one of a kind surgical skill and his after surgery care I am healed. My right leg is like new. Thank you Dr. K!

Review of Dr. Delos

-

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.

Review of Dr. Kavanagh

- |

I attribute my remarkably quick, almost painless recovery from total hip replacement to Dr. Kavanaugh's expertise. Every office visit was efficient. Dr. Kavanaugh listened to all of my numerous concerns and addressed each of them, patiently and concisely. He was quite assuring and honest in terms of his preferences for how he approaches certain aspects of the procedure. I asked if I might speak to one of his patients who was a tennis player and had returned to tennis, as is my goal. He complied and I received a call from a patient who had had three surgeries with Dr. Kavanaugh and gave him glowing reviews. Post surgery, he visited me within hours. An added bonus: my wife, who is in the skin care business, says the scar from my surgery is so minimal and healing so well that she'd have Dr. Kavanaugh work on her face if she ever needed it, lol!

Review of Dr. Kavanagh

- in New York, NY |

Dr. Kavanagh did a total right knee replacement for me in April. Prior to my surgery, I was given a very comprehensive packet of information and attended a class outlining what the procedure and aftercare would be. A bending machine was sent to my home, set up, and I was taught how to use it. My surgery went very well, and I received excellent care in Greenwich hospital along with several sessions of physical therapy. I also received at home PT and then outpatient PT as well. I was driving within three and a half weeks. My follow-up visits went very well. I highly recommend Dr.Kavanagh.
