Verified Patient Reviews
Excellent visit all around. Everyone was helpful and I hardly had to wait. Wonderful team!
As a new patient, I had completed their questionnaire online and only had two documents to sign when I checked in. My wait as only a matter of a few minutes until I was called in to an examination room, 15 minutes before my appointment time. The nurse took vitals and asked a number of questions related to my visit and completed it within 15 minutes and right on my appointment time. Dr. Masters came in within 5 minutes and professionally went through questions and answers culminating in a suggested treatment and then took me to the appointment desk where my next appointment was arranged. My total time in their office was about 55 minutes and wait time during that totaled 10 minutes are less. I am quite satisfied with the Dr. Masters and his office.
Wonderful! He listened and gave me the plan for moving forward with testing??
This doctor is the most highly qualified physician I have ever used. Dr. Masters makes you feel comfortable in allowing you time for all questions and very informative answers in which you can understand. He explains the situation in terms which is our language and not physician talk. This doctor does not rush you through your visit so that you do receive all answers needed before leaving your room. I also must say that this doctor saved my husbands life by knowing his problem that other physicians could not figure out, thank you!
Very professional and took his time by asking a lot of questions to gain a better understanding of my problems. I did not feel rushed and he was friendly and made me feel comfortable.
I go in every 4-6 weeks for an adjustment on my gastric pacemaker. He does that just fine. But he completely dissmisses all my other concerns. I tell him the same thing every visit. I tell him about my pain increasing, my weakness, my inability to eat, but he never even acknowledges it. I have gotten no help from this doctor at all. I only go for an adjustment on my device.
I had a great appointment with Dr. Masters, I've been seeing him for years and he has always provided me with the best care. His new office is incredible!

Wish I could go there for all health needs. I've never had such excellent care in my life and the entire staff is the same. They truly care and are top skill levels. I'm very satisfied and they raise a "high bar" that others should follow. Thank you
Went very well, provided good information.
My mother had been suffering from a flare up of gasroparesis since 12/10/16. She had been in and out of emergency rooms and was hospitalized for 3 days. We had seen a primary care physician who wasn't able to help and a gastrotenologist in Corpus Christi who told us there was nothing he could do for her. My mother was in severe pain, spitting up mucus constantly and couldn't eat or drink. It was like her condition was deteriorating . We were finally able to book an appointment with Dr. Masters (who I found on a G-Pact TX motility website). She saw him on 1/19. His staff pulled all her medical records in one day and were able to see her that week. His staff is wonderful and I love his bedside manner. He let us speak and answered all of our questions. He truly listened to all of our concerns which is so rare from previous doctors we have dealt with. He put her on various meds for treatment and I'm happy to report that the next day she was feeling better. I feel like God directed us to him and he helped saved my mother's life. He is brilliant and truly is a blessing to my family and I would highly recommend.
For the first time in a long time---we have hope that someone knows enough/ cares enough to find out what is wrong.
Dr. Masters was a good listener and gave good advice. The staff was very friendly and helpful. I would recommend Dr. Masters to anyone.

I've been going to Dr. Masters for 16 years. I really love going to him because he's always taken care of my ailment in or out of the hospital. I'd highly recommend him to anyone with gastro problems.
Very understanding and ordered tests to find the answer to my problem.
Dr Masters always takes the time to listen to my concerns and answers all my question fully. Always given me options for my treatments.
A very compassionate doctor who is highly specialized and trained in his field of expertise. He is only one of two doctors who performs gastric neurostimulator surgeries in San Antonio. Most patients who are suffering from the same type of disorder have to go to either the Mayo or Cleveland Clinic. I am extremely grateful to have a specialist here in San Antonio who specializes in the treatment of rare gastrointestinal disorders. Dr. Masters has greatly improved the quality of my life.
Dr. Masters presented various options available for my issue. He listened to my concerns and was able to help me choose the best option for my lifestyle.

My only dissatisfaction was the nurse who took some information from me prior to my seeing the doctor. She was "snippy" and impatient when I was answering her questions. Not very hospitable.

Dr. Masters has been my Doctor for over 15 years. That tells you how pleased I am to have him as my Doctor. I have referred him to several friends and they are very pleased as well. He is very professional and right to the point, always right on top of what issues I may have.

I have been to Dr. Masters three times and I am perfectly satisfied with him.

I have been very please with Dr. Masters. I have seen him for several years now I would highly recommend him to any one.
We had only seen Dr. Masters one time last year to get established so when we called today to be seen we expected to be seen by another Dr or booked for another day. We were told he was booked today, but received a callback from his nurse within 15 minutes about a cancellation and were seen within 3 hours. Dr. Masters was quick to review symptoms and ordered X-rays and blood work that day. We anticipate a diagnosis this week, which is good with 15 days left in the year we can still use our insurance before starting a new deductible.
Everything went well with my follow up with Dr. Masters.
The receptionist help work through a problem I was having with patient portal walking through it step-by-step. The entire time from entering the office to exit was 20 minutes. This included talking with office staff regarding a problem with my insurance for a prescription issue.
I feel Dr. Masters holds back. If you don't ask he won't advise. I would welcome any advice he felt beneficial. I sincerely feel Dr. Masters is a excellent doctor.

Only thing was his demeanor, I was his last patient and he seemed to be in a hurry.
It went well.
Very knowledgeable. Answered all my questions. I have total confidence in him.
Dr. Masters was very polite, and he took time to answer every question that I had. I was in the back speaking with him in less than 30 minutes from walking in the door. That is refreshing, as waiting times for most doctors can be up to 2 hours.
Dr. Masters has been and continues to be such a blessing. He is not just outstanding in his practice of medicine but is equally so with is bedside manner. I consider myself to be very fortunate to have Dr. Masters as my physician.

I've been a patient of his for over 10 years, and just love him. I would recommend him to anyone with digestive issues.
Dr Masters is very informative, he listens to your concerns, answers all your questions, explains your alternatives and provides his suggestion and explains why! So far he seems to be a great doctor! I researched many GI doctors, he was my choice, I am very hard to convince! Most of the other doctors in his practice are excellent as well!
I felt that Dr. Masters was very attentive to my symptoms in spite of my inability to describe fully my problems. I was have a particularly bad day with my back and stomach and could not really explain which bothered me the most. He recommended that I have a colonoscopy which I agreed to. I would recommend him to my friends.
Extremely Knowledgeable, thorough, kind bedside manner. Even if I have waited extra time when I am inside the room it will always will be worth any wait. He treated my mother as well.

Dr. Masters exudes competence and professionalism. I trust him with my life. His bedside manner is wonderful, and he is very patient and kind.
He's an AWESOME Doctor.
I thought I was going in for an endoscopy, not just to sit and talk with Dr. Masters. I now had to make another appointment for the actual procedure. I believe this first visit was actually a waste of time. I could have been asked the same questions on the actual day of the procedure. Now there will bd two separate group of charges and two separate times of having to be away from work. Nothing against Dr. Masters, but this is definitely not efficient or money saving.
always a pleasure
Dr. Masters is always very attentive and explains everything in a manner that I can understand.
Always professional! Thank you!!
Always a pleasant and professional atmosphere at the clinic. Appointment times run smoothly and are provided by a warm and caring staff. Dr Masters is easy to converse with and makes the visit comfortable considering the subject matter. Thanks for caring! Judy

He is by far one of the best doctors I have ever had the pleasure meeting; he is truly a knowledgeable and professional doctor in his field.
I first came across Dr. Masters years ago when I was in the ER, and he's been my doctor ever since. He's extremely pleasant and attentive. He seems to know right off hand your issue, but orders tests to be sure there's nothing else going on. My husband had some issues with acid reflux and was on medication for a brief time. He feels that Dr. Masters is also the finest doctor he's ever been too.
Dr. Masters always takes time to explain my medical problems and answer questions. After 3 years of seeing several GI doctors he diagnosed and started treating my condition. He and the staff members are always very friendly and pleasant. In addition my phone calls are returned in a timely fashion.
He is the best. He really listens & works together with his patients
Dr Masters is always interested in my progress. He praises my efforts and accomplishments.

He is highly respected by doctors and nurses at the hospital. Yes,I highly recommend him to all my friends and famil.
The staff is so friendly and treat you like you are the only patient except for Vleronica at the front desk. She seemed a little bit preoccupied, she should either answer calls or check people in but not both. Dr. Masters was so helpful and took what we had to say into account when he treated me. His nurse today was wonderful, she saw my., blood sugar was low and hunted down some apple juice for me, thank you so much??.
