"I would highly recommend Dr. Kosmala & GI Alliance. Very thorough & professional. The staff are very caring a good experience from the check in desk to the Discharge door. Professional & caring staff. I would highly recommend them."
"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!
