Thomas Sweeney, M.D.

My appointment with Dr Sweeney was excellent. As usual he was thorough and very helpful. The only negative was that I am selfishly saddened by his pending retirement, but I wish him all the best in the future.

Michael Ozga, M.D.

I felt comfortable with Ozga immediately. He’s got a calm, reassuring demeanor that makes it more relaxing and easy to talk too. He shows genuine concern and compassion and that is very much appreciated. I feel if there is something to be found, he will be the one to find it.
