What our patients think

- Sherrie, Charleston

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. Each and every person was kind, had a smile on their face, took up time with me to make me feel comfortable and at ease. They explained everything to me and made sure I knew what to expect. Thank you Dr. Royall and your staff. I can’t imagine getting better care anywhere! May God bless you and your staff.

- Karen, Summerville

I want to thank Charleston GI for my colonoscopy today. I was treated so professionally and taken into the procedure on time. 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’ll be back for my 5-year colonoscopy.

- Heather, Charleston

I just wanted to say a huge thanks to the staff and Dr. Marstellar for helping me. I came into the office with extreme pain. He admitted me to the hospital and three days later had my gallbladder out. He also really encouraged me to have my colonoscopy, which no one ever wants. He saved my life by pushing me to do the procedure. I had 28 polyps that were not looking good. I probably would have had cancer, but thanks to Dr. Marstellar I’m ok. You will never know how grateful I am for your kindness and caring. All of you are the best!
