Robert Jeffrey Zwiener, MD

We saw Dr. Zweiner from the time my son was born 3 months premature until he was 3 years old. During this time, Dr. Zweiner repeatedly tried to ween my son off his reflux meds. He minimized my concerns and seemed to have little understanding of pediatric feeding issues. My son was refusing most foods and Dr. Zweiner sent in a nutritionist who talked to me about how to get my son eat more broccoli. The child was eating maybe 3-5 foods at the time. My son was under 3% on the growth chart and was vomiting several times a day. At one point, Dr. Zweiner suggested I was just a nervous preemie Mom. I asked Dr. Zweiner if my son needed to see a Speech therapist for feeding issues and he shrugged his shoulders and said, "what are they going to do." We saw a feeding therapist anyway who ultimately was very helpful. After THREE years, my pediatrician insisted on additional testing for the cause for the low weight. Dr. Zweiner did an endoscopy and came in and said "your son has angry and… severe reflux and will need reflux meds." He has been on meds since then and we changed doctors immediately. Dr. Zweiner's nurse routinely did not return calls and was not kind. Overall, I can not recommend this practice or this Doctor. I'm grateful we now have a choice for GI practices in Austin.

We were trying to advocate for our son to get a feeding tube because we knew he likely had a syndrome and would continue to have difficulty feeding. Dr. Zwiener refused to acknowledge our son's difficulties, saying that his inability to eat enough or gain adequate weight was our fault for allowing him to cluster feed and upping the calories in his formula. When Dr. Zwiener saw my son for the first time he had microcephaly, was eating far less than he should, and had abnormal physical features. He instead chose to spend our appointment flirting with my son's speech therapist, trying feebly to speak Spanish with her and saying what a lovely smile she had. When I tried to ask questions he would bark at me, telling me he was busy speaking with her or was not done explaining his (incredibly misguided) thoughts. 3 months later my son got a g-tube through a different hospital (thank God) and a few weeks after that received a diagnosis of a rare genetic mutation that indicated he would require… assistance feeding for a minimum of at least 6 more years. If I had followed this doctor's advice (wait longer between feeds until he shows stronger cues - which my son is incapable of, reduce the calories in his formula, not to be concerned) my son may not be here today. Do NOT take your child to see this man - he is a hack who is resting on his laurels instead of actually fully assessing his patients.

He saved my son many times. He is a very smart and intelligent dr. He spends time with my son and I at apps, he follows up, he isi always there when we need him. He listens and we listen to him. Don't let anyone every tell you to not go to him, he is amazing! My son has been on death's beds many times, and Dr. Z saved him! I owe my son's life to him! Amazing and brilliant dr.

Dr. Z is the most brilliant Dr I have ever met. He cares about his patients, he listens, he is very knowledgeable. My son had a liver transplant and was very sick, he saved his life by coming up with diagnosis that has helped him tremendously. He continues to follow him, and has saved Cole's life many times. He is amazing and such a great doctor, his team of nurses and staff always are thoughtful and caring about us and always follow thru with what is needed. I couldn't live without Dr. Z, my son turns 18 soon and I am not sure I can leave Dr. Z, he has always been there for my son. Thank you Dr. Z for your amazing ability as a dr!

would highly recommend

My son was diagnosed with IBD and PSC (a chronic liver disease) nearly five years ago. There are many good doctors, but what sets Dr. Zwiener apart is that he understands the human side of the equation. He understands not only the physical and emotional impact on the child, but the impact on the parents as well. Dr. Zwiener spends as much time as necessary to explain what is going on and to answer any and all questions the child and/or parents have. I could go on and on, but the bottom line is that Dr. Zwiener is an excellent doctor and I will always be thankful for the care that he and his staff have provided for my son. We could not ask for a better doctor or better care than Dr. Zaiener provides.

Dr. Zwiener is one of the best doctors I have encountered. He is very devoted to helping my child and spends as much time as is needed to fully address all concerns.

Dr. Zweiner treated my son over 10 years ago, but I still remember him as very professional and very caring. He related well to my son and was very encouraging to him. The experience and the care that we received with Dr. Zweiner was excellent and I would recommend him wholeheartedly.
