Patient Testimonials

“I just wanted to say thank you to each person who I came in contact with the day of my procedure . . . from the receptionist to the nurse who wheeled me out. Every person had a smile on their face and took their time to make me feel comfortable and at ease.”

“Dr. Marstellar saved my life by pushing me to have a colonoscopy. I had 28 polyps that were not looking good. I probably would have had cancer, but thanks to Dr. Marstellar, I’m okay. You will never know how grateful I am for your kindness and caring!”

“Every person I was in contact with was friendly and explained what to expect. I will recommend Dr. Irions to all my family and friends. Your facility in Summerville was so clean and beautiful.”

“I had a colonoscopy this week with Dr. Gourdin. Everyone was wonderful… felt like I was visiting with friends.”
