"Dr. Clark et al. were a joy to speak with and had a really positive attitude during my preventative colonoscopy screening. They were unable to find the stick that my wife says is up there, but everything considered I would highly recommend this team to anyone looking for a professional environment and quality work."

"The entire staff at GI alliance has always taken amazing care of me. I’ve been a patient for more than ten years and they always make an uncomfortable situation so much better"
"Doctor Clark is great! I think the office is a little too busy though. It’s hard to speak with him personally a lot of times and you end up speaking with a nurse and the nurse practitioner makes a lot of the decisions on your health which is not bad but you’re paying for the doctors advice on your health issues. I do highly recommend Dr Clark he has been amazing with ECD banding procedures he has performed on me and the staff is excellent in the surgical area as well as the main office."
