Very happy I found Gastroenterology Associates and Dr. Haydek. The practice communication is fantastic and everything runs like a well-oiled machine. Everyone I came in contact with was knowledgeable, friendly, and helpful. Dr. Haydek is communicative and thorough. He’s a great listener and strives to make his patients comfortable and well informed. I can’t recommend him enough.
