MaleAbout M. Behzad Zafar
Professional Statement
Dr. M. Behzad Zafar is a board-certified gastroenterologist with significant clinical experience in managing digestive health. He trained at the Baylor College of Medicine in Houston, TX, where he completed his Internal Medicine Residency in 2009, and his Gastroenterology Fellowship in 2013. He provides comprehensive care for a wide range of gastrointestinal conditions, with a strong commitment to evidence-based medicine and patient-centered care. He is a member of the American College of Gastroenterology, and has been consistently recognized as a Texas Super Doctor and one of Houstonia Magazine’s Top Doctors.
“I chose a career in Gastroenterology because it gives me the opportunity to help people in many different ways. From routine colon cancer screenings and polyp removal to managing acid reflux, abdominal pain, and digestive conditions like Crohn’s Disease and Ulcerative Colitis, I work with patients across a wide range of concerns. I also perform endoscopic procedures, treat liver conditions such as Hepatitis B and C, and provide care for many other gastrointestinal issues. I completed all of my post-graduate training in Houston’s Texas Medical Center, where I developed not only my medical expertise but also a strong connection to this city. Houston has become home to me – I love its people, its culture, and its energy. It is my privilege to serve our community, and I remain committed to providing high-quality care with both expertise and compassion." - Dr. Zafar

I had a routine colonoscopy by Dr. Zafar. He is professional, yet friendly, and gives you every confidence in his diagnosis. He took the time to meet with me by telehealth and explained his recommendations for follow-up. He could have written a letter, but by talking with him I felt so much better about further treatment. He is extremely thorough and has such a pleasant manner. I highly recommend Dr. Zafar.

Dr Zafar has always taken the time to hear my concerns and never in a hurry to get out the door. That’s rare these days and it’s unfortunate for patients they have genuine concerns or fears. I personally appreciate that quality. Sheila is great as well. Friendly and helpful.

- 5 out of 5 starsReviewed on 10/5/2021
Dr. Zafar is hands down one of the best doctors I've ever gone to. A normal doctor visit includes sitting in the waiting room well past your appointment time, then sitting in visit room waiting for doctor, doctor rushes in for 3-5 minutes, solves or doesn't solve your issue then moves on to the next patient. With Dr. Zafar, everything was right on time. No waiting at all. When he came into the room, he sat down, took notes, listened to my issue. Talked about several different possible causes and solutions. He showed he is very knowledgeable and possesses the ability to think critically rather than take a 'one size fits all' approach. He took time to ensure all questions were answered and that he had covered all potential paths forward to have the issue resolved. I was very pleased with my experience and had positive interactions with all staff. Would highly recommend.

Dr. Zafar is a blessing. He diagnosed and treated me correctly. He is very professional and took time to answer all of my questions and explain many things that I was not aware of. I prayed that God would send me to the gastroenterologist that he wants me to have and I truly believe that Dr. Zafar is the one. Ty and Shiela are very kind, patient and professional. I highly recommend Dr. Zafar and his staff.
- 5 out of 5 starsReviewed on 11/17/2021
I can honestly say that Dr. Zafar is the Beat doctor that I have ever seen. He sat with me and my daughter for over 30 minutes. There was no waiting, he was not rushed and he answered all our questions. He is extremely knowledgeable, he explained what steps I need to take in very clear instructions. There are steps he can take to improve my health, however, he suggests I contact another specialist for my severe abdominal pain. He explained my blood work so I completely understand what is wrong. He took a step out to look at all my test results and is doing more blood work. I can honestly say that if anyone could help find out the cause of my pain it’s definitely him. I feel so blessed that he was able to see me in his office. His staff is amazing, kind, caring & knowledgeable. He is a very special doctor who I would highly recommend to my family, love ones & friends.

I love this doctor he is more than great But I am little deaf from old age and every time I talk to his nurses they think I am screaming They are always late in answering the telephone I understand but if a pharmacy is calling them while I was present they cannot say they didn’t call and they make it so hard to obtain the orescription of my ibs Ladies staff this is urgent it’s not a joke , please return calls I love your doctor but I feel sometimes the staff is less of a professional than he is

Dr. Zafar has been a very competent GI. He explained all my options to me and detailed his diagnosis and why trying multiple treatments as once was good. His staff can be a bit hard sometimes to get on the phone, but I just use the ZocDoc app to handle all my appointments, so it didn't affect me that much.

Dr. Zafar started off giving his standard spiel at a sprinter's pace, but once I asked questions and talked about my particular details, he quickly changed gears to address my specific case in a clear, thorough, and unrushed way. His explanations were excellent and clearly adapted to my level of understanding. He was very generous with his time. In this first appointment, I could immediately tell that he is knowledgeable, approachable, and patient-focused. Nice first impression, doctor!
