"Dr. Kosmala’s thorough and unique examination of my condition was very welcomed by me. He took about 20 minutes just asking questions and then recommended a simple course of action including a change of diet. Then he will be more aggressive once I return in a few months. Very nice man too. Really like his demeanor."
