S.D. Google

Dr. kosmala was amazing, he was very friendly, he asked a lot of questions about the issues I was having he seemed like he really cared, and he did more for me in one visit then the first doctor who originally diagnosed my condition. I'm glad Dr. kosmala took me on as a new patient hopefully he will help me get to the root of the problem.
