The experience with Gastrointestinal Consultants of San Antonio and Dr. Ayyar was great. I was pleased with the efficiency and timely manner I was able to get an appointment. The staff at the center where the procedure was performed were efficient and friendly. I’ve had this performed procedure many times before and I have never had this procedure completed so fast. My appointment was scheduled at 11:00 am and I was out at 11:45 am. Dr. Ayyar was very friendly and professional, he explained the findings of the procedure very well. I definitely recommend Dr. Ayyar.

Dr. Ayyar performed a colonoscopy procedure recently. It was my first procedure of this type and I was pretty nervous heading into it. The whole team did a great job of educating me on what to expect prior to the appointment. On the day of the appointment the staff did a great job of calming me and the process from check-in to recovery was excellent. Dr. Ayyar was thorough in his work and the procedure was quick and painless. The follow up was excellent also. I’ll definitely use Dr. Ayyar again due to his performance and professionalism.

From the scheduling staff to the surgical staff, I was treated as a person and not a number. All were concerned about me and my needs and wants. Surgical staff were very compassionate and professional. Dr Ayyar is a true professional and has a great bedside manner. The entire process made a lousy procedure truly bearable
