I'm a repeat patient of Dr. Harrison. He is compassionate, patient and explains procedures in detail, no matter how many questions I had. It's always a pleasurable experience with the doctor and the entire staff. Although I hope not to see him as a patient if I need to it will be Dr. Harrison and team, again.
