However, I was checked in within about 10-15 min, only waited in waiting room for about 5 before I was called back. The staff at Gastroenterology Consultants of San Antonio were professional and excellent. The anesthesiologist was super kind and understanding. Dr. Challa is a very sharp young physician... The kind I want working on me. 5 Star. This was my first old man procedure, was much less scary than I imagined! Thanks!"

"Dr. Challa and the staff at Gastroenterology Consultants of San Antonio were very attentive when I was there for my procedure. From the moment I walked into the facility the receptionist acknowledged me and explained all the paperwork I needed to sign. Then when I was called to the back the nurses stayed with me and explained everything that was going to happen. The Chief Anesthesiologist came by and explained the anesthesia that I would be given to include side effects and how long it lasts in my body. Once I was rolled to the operating room I meet Dr. Challa and he explained everything that he was going to do and informed me that he would meet with me after I woke up from the anesthesia. Dr. Challa showed up shortly after I woke up from the anesthesia and explained everything he saw during my procedure and gave me a copy of all my paperwork. Thank you again for making my experience pleasant."
