I look forward to my son's appointments with Dr. Harrison. Not only is he extremely knowledgeable and professional, but he also has a great demeanor. He is easy to talk to and is a great listener. My teen son likes him, too. He seems comfortable when he talks to him. Doctors like him are hard to find. I highly recommend him

Had a great experience with Mr. Harrison. He had a pleasant demeanor—personable, professional, and easy to talk to. He took the time to listen to me as a patient, answered all my questions, and explained everything in clear detail.

I had an excellent visit with Zacharia Harrison. He was attentive, really listened to my concerns, and took the time to answer all of my questions in a thoughtful and thorough way. I never felt rushed and felt comfortable and well cared for throughout the entire appointment. It was a great experience, and I would highly recommend him.
