This compassionate, knowledgeable physician has treated me with respect and compassion on every visit. Dr. Ramirez listens to me, offers options, and never once has rushed through my visit. I must also give high praise to his staff. When my test results come in, they contact me promptly and pass along the results and recommendations from Dr. Ramirez. I feel blessed to have Dr. Ramirez and his staff taking care of me, I cannot imagine being in better hands.

I was impressed with the entire process and entire staff at the Gastroenterology Consultants of San Antonio during my colonoscopy procedure. This was my third colonoscopy and the smoothest. Everyone was professional, kind, they listened and answered all my questions. I loved how efficient they were when it came to being on time.
