Review of Dr. Kowalsky

-CT, CT |

I saw Dr. Kowalsky for an ACL reconstruction - he was patient and kind and took the time to answer any/all of my questions. Surgery went extremely well and I have full range of motion back in my knee.

Review of Dr. Miller

- in Yorktown Heights, NY |

Total shoulder replacement completed 10/31/18. Diagnosed with bone on bone grinding and ostheoarthritis. Had unbearable pain and unable to lift my arm above my shoulder joint. After 12 weeks I have no pain and better than expected range of motion. Was amazed at the lack of pain after the procedure. Used no pain killers whatsoever. Dr. Miller is a gifted surgeon who uses the latest technologies and still maintains a personal touch. Planning on my left shoulder procedure next year.

Review of Dr. Hindman

- in Greenwich, CT |

Horrific! Look around before you use this MD or his practice. Intense leg pain before the Christmas holidays - and the following happen a) Gave me crutches and said "good luck /take Advil" . Seriously , when you're screaming with pain -and it's a holiday weekend, no pain relief, no therapy...just hobble around?b) No follow up call.. I had to reach out to them 5 days later. c) Tried to get an MRI approved asap... Insurance company claims this office didnt fill out the forms right. More...!

Review of Dr. Kowalsky

- in Larchmont, NY |

Dr Kowalsky and the entire staff at ONS are professional, incredibly knowledgeable about their individual crafts and really cared about getting my knee/quad and leg back to normal so I can resume my daily activities. Dr Kowalsky, despite being very busy took the time to respond to a question via e-mail and I can’t name another Dr who would take the time to do so! Additionally ONS is “one stop shopping” from setting up appts, MRI, surgery and PT all under one roof! Their PT staff is exceptional!

Review of Dr. Kowalsky

-none |

I had a very serious shoulder injury. Dr. Kowalsky clearly and completely explained the extent of the injury and the surgery needed to repair my shoulder. He also accurately predicted the recovery time and effort needed. Dr. Kowalsky always took as much time as was needed to thoroughly answer every one of my questions. I would definitely recommend him to anyone who has experienced a shoulder injury.

Dr. Berliner is a wonderful doctor. He performed two anterior hip replacements, ten months apart and I have had exceptional results, He is professional and patient and I highly recommend.

Review of Dr. Fiore

- in Tarrytown, NY |

Very poor judgment. Too eager to recommend surgery when other options are available and more logical. Poor diagnostic skills, as well as patient relations.
