I’ve had Ulcerative Colitis for years, and thought I was going to die, but Sarles & Chris got me on the right medication. I couldn’t eat, leave the house, staying sick, hurt extremely bad, and in the bathroom every hour of the day. Now I’m able to do much of whatever I want with no issues at this time. To me they are my Angels 😇 wether they know it, or not. I can’t thank them enough for saving me from a horrible life i was living! This is not the only colon doctor I’ve had, but I will tell you with a 100% that they are the very best to me, and would not use any other. If your having any colon issues, etc., please go see them in Rockwall, Texas!!!! YOU WIL BE GLAD YOU DID! If I could, I would give 10 stars. Thanks Dr. Sarles & Dr. Chris 👍🏻"
"One of my favorite doctors. Why can’t more be like him? As others have said, he acts like he truly cares about your health. He isn’t like other doctors that have one foot out the door. He sits down with you and listens to all of your concerns. I look forward to chatting with him than most other. I hardly ever bother writing reviews, but he’s earned it. It looks like he’s the one that’s responded to the negative reviews on Google, kudos doc! I’m an entrepreneur myself and I notice things like that."

"Dr. Sarles is an extremely attentive doctor. When he comes in he has already reviewed my chart and history and knows why I have come to visit. He has real questions rather than just expecting a repeat of what has already been explained. His office staff and nurses are kind and keep patients well informed. Also, I love the sign-in kiosk. What a idea for patients! It is so much easier to just verify information and select yes or no rather then refilling pages and pages of paperwork that was also filled out at all other visits. Great Doctor, Great Office!"
