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.

Dr Sweeney is a heartfelt, caring dr and support system. He was there for me for the 2 worst times of my life...I consider him a friend and wish all Dr's. were at least half as caring, concern and attentive as he is...
