I have been seeing Dr. Castro for a few years now. I am in my early 40s and have lifelong GI issues and IBS. I have had other GI doctors in the past, but Dr. Combs is my favorite by far. He is incredibly knowledgeable and has a lot of hand’s-on procedural experience, yet he also listens to you as the patient and considers your feedback in his recommendations. He talks to you as a friend and you feel very secure that he is providing you with the best care possible. Highly recommend.
