Dr Haas, is exceptional! I had a colonoscopy, yesterday. And, because my bp was low, he din’t knock me completely out! Although, my bp always runs low, he cared enough, to give me just enough anesthesia to keep me comfortable. And, for that, I’m grateful. Sincerely, LeAnna Ames

I recently had my first over-fifty colonoscopy with Dr. Haas. He is a fantastic doctor! He and the nurses and technician are very friendly, professional, and efficient. They made the process so simple, it put me at ease. The procedure was done very quickly and efficiently. I highly trust and recommend Dr. Haas.
