Dr Ayyar was very kind and calming. He spoke to me patiently and reassured me of all that was going to occur. The procedure went off without a hitch. I highly recommend him and this practice. The whole process was very smooth and easy to do. My only complaint was it was very difficult to get anyone on the phone and to make an appointment. I submitted a request for an appointment online and was never contacted. I had to call. And when I did call, I would either wait for a very long time or have to put my number in for a callback. And that callback wasn't always when I was still available. That was painful. Otherwise, the day of was a quick and smooth experience.

Dr. AYYAR is my new primary GI physician. He did my colonoscopy and labs. He changed his schedule to do a consult immediately and was very receptive to patient suggestions. He explained in simple terms what I needed to do and he followed up immediately. Highly recommended. Very compassionate! God bless and be Safe. Randall ADKINS

Dr. Ayyar and everyone was great. They made probably the most uncomfortable thing I've ever done as comfortable as possible. Everyone was very communicative about every step along the way. Would definitely recommend.
