What patients say about Dr. Ambrosia

  • Thanks to my care at KOC, I am getting back to full range of motion, strength, and grip. Dr. Ambrosia is a very caring person with the most wonderful bedside manner I have ever received from a surgeon. He explained his very conservative approach, indicating a desire to avoid elbow replacement surgery and the associated complications. I am so thankful that Dr. Ambrosia was put in my path to help me on this difficult journey back to health.

  • Thanks to my care at KOC, I can use my thumb without pain or it constantly clicking in and out of place. The relief was almost instant.

    Dr. John Ambrosia was very patient and understanding with me being 'chicken' when it comes to needles. He took time to explain everything that would happen and didn't make false promises about the pain. It did hurt, but not long and the results were well worth it. I wish I had not waited as long as I did to go get it checked out. :)
