"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."

"Dr. Kosmala is an amazing physician and an admirable person inside and out. My family and I can not say enough good things about him and his demeanor. He is very knowledgeable, caring, kind, has great bedside manner, and most importantly, he is highly skilled and attentive. We rarely meet any doctors that spend more than 2 minutes talking to us while leaving the rest to the nurses. However, Dr. Kosmala doesn’t leave the room until all questions are answered. Even if he has 10 patients waiting for him ( and he does do EGDs back to back) he still makes sure he doesn’t leave the room until you are reassured and comfortable! Absolutely recommend!

"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."
