I was referred to Dr. Martinez by my primary care doctor for my first colonoscopy. Dr. Martinez and staff were very professional and answered all of my questions. I highly recommend this practice!

My entire experience with the Gastroenterology Clinic of San Antonio has been a horrible one. Getting someone to answer the phone to schedule a procedure is a nightmare. You can leave a voicemail, but IF you receive a call back, it will be 7+ days; this includes office personnel, schedulers and medical assistants. My endoscopy procedure went alright, the medical staff that I had assisting me that day were great, but the lack of communication, attention, and general courtesy in any other encounters is completely upsetting.

At this point, I am still pending results from a biopsy that nobody knows if I actually had or not. I will be taking my business elsewhere because I am absolutely exhausted with dealing with the clinic's lack of professionalism.

HORRIBLE! Go to another place if you can! New pts need to wait 5 days for a phone call back. Appointments scheduling is nonexistent. And if you need to schedule a colonoscopy you will be waiting forever to get a call back! 7/19 I called and spoke to exceptional employee by the name of Gloria. She is what a receptionist is! Only star there. She gets the only star I give this company.

She told me she sent the procedure scheduler for Dr Randall a message because I have left the scheduler 5 messages over the course of 4 weeks. And not once did I get a call back. She told me she will send a direct message to Dr. Randall assistant so that they may inform the doctor of the lack of common curiosity of a call back to schedule a procedure!

When I finally get a call back from Delilah i had to tell her that her attitude needed to be adjusted! I don't know what is going on there but this has been by far the worst!

Decided not to use this facility or the doctor after repeatedly requesting a callback from the clinic and hearing nothing. After several days of hearing nothing, I cancelled my appointment and have tried for two weeks to get a refund on the money they required me to pay when making the appointment.

I'm a colon cancer survivor and have had Crohns Disease for 36 years. I have both an illeostomy and a urostomy. I started seeing Dr Martinez nearly three years ago. He has worked diligently to find the right medication and treatments to improve the quality of my life. Each time I've been hospitalized he was there everyday to check on me and assure I had everything I needed.

His knowledge of Crohns Disease is vast and he explains things so I can understand it. Dr Martinez goes way above and beyond to ensure my health is monitored. Excellent communication always. Also a big thank you to his assistance Amanda. She is amazing and is so organized and ensures she communicates all details with me. Another big plus for me is that Dr Martinez and Amanda are just nice people. They make you feel like you are their only patient and the focus is solely on you. I highly recommend Dr Martinez to partner with you in your journey for a healthy life.

My 23 year old Son with Autism visited Dr Vizuete today. Dr Vizuete bedside manor was exceptional. He spoke directly to my son with patience and concern. He explained clearly to my son what he would do during the exam and asked permission each step of the way. I left the office with my son amazed at this doctors skill dealing with a special needs individual.

I had the pleasure of being a patient of Dr. Franz Zurita and he is by far the best doctor I have ever seen. His bedside manner is amazing and he figured out my condition in one visit when the gastro doctor I had in the past couldn't figure it out in two years. He is very kind, caring, and responds quick to messages on the portal. Whenever I needed an appointment quick, he did what he could to squeeze me in. Such a kind man! HIGHLY RECOMMEND SEEING HIM.

Dr. Vizuete was amazing! I cant speak highly enough. I was more than a little disappointed in the staff when I made an appointment for my 1st visit - and they had to call me back and reschedule. BUT my visit today more than made up for it. He was extremely polite, professional, caring, and just made me feel heard. I felt welcome and that he took me seriously.he spent 30-45+ minutes talking with me and carefully explaining our plan for testing/treatment.

Its not easy to find such good beside manner now-a-days. Then he and is MA made sure I had both their business cards to ensure I could contact them with any questions/concerns. I was/am quite nervous - so it meant a lot that he took the time to make me feel comfortable.

My experience with Dr. Martinez at GCSA was very good. He answered all my questions and ordered the necessary exams when I visited his clinic. He was always very attentive and professional. When my husband was referred to a Gastroenterologist he also visited Dr. Martinez. After reviewing all his current medical information and several tests ordered we were relieved to get good news. Dr. Martinez took the time to call him personally and made the process very pleasant.
