Reviews for AG Westlake Hills, TX
"Much appreciate the simple, open question of this! Dr. Tau was a Mensch: respectful, light-hearted, thorough and clear in presenting information and in answering my questions. In three quarters of a century seeing physicians, I have never felt this positive about the quality of care and the clarity of information I received. Honestly. Dr. Stephanie G. Ortega"

Simple upper scope procedure, but they did a great job explaining everything, prepping me for what to expect, and making sure all my questions were answered during my visit. Very professional, courteous, and on time. Couldn’t ask for more!"
"Love this office and Dr. Sperling, good people!"
"Dr. Haveman is very intellent. One doesnt have to say much. He checks you out with his hands as receptors which most doctors don't. I know I've seen many for the same reason. He is very very intuative. He knows what needs to be done. His brain races at 110 mph which most people misinterpret as rudeness or him not caring. He knows his stuff. He said he'd take care of me and he did especially during and after my procedure. I would put my life in his hands any time. Oh his staff at procedure place and at his office are very professional and very attentive to one. I am blessed that they are in the path of my journey."

"This will be my 3rd colonoscopy with Austin Gastro and I needed to find another doctor within the group. I chose/met Dr. Anupama Duddempudi for my pre-colonoscopy appointment. She was so warm and welcoming and made me feel very comfortable. As much as one can look forward to having a colonoscopy... then I'm glad I chose Dr. Anupama Duddempudi! The staff was also very professional and the location for my colonoscopy, Westlake Hospital, is also close to home! All was a win, win!"
"Dr John Tsia is a Super Doctor & I completely entrust my life in his care. Austin Gastrology has many many competent good doctors. But Dr Tsia really stands out in his careful, kind care!! I drive so much further to see him after he relocated because he's worth following!!! He cares for his patients so much that he has actually called to do a follow-up to see how I'm doing."
"Dr. Sperling and his staff were great. I have been having gastro issues for awhile that have been elusive and really bothersome. I was so glad to get to see him and sure enough he was able to get me started in a positive direction. I appreciated his calm manner, level of expertise and overall approach."
"I had several problems pharmacy related, don't know if it was the pharmacy (CVS) or Austin Gastro, but the doctor was very nice."
"My experience with Dr. Dalton-Fitzgerald was nothing but excellent. I felt like all of my questions were thoroughly answered (and I have a lot of questions!!), and all of my concerns addressed with empathy. Although the causes of GI distress are often elusive, which is the case for me, I feel like Dr. Dalton-Fitzgerald is committed to helping me manage my symptoms so I can get back to a normal life."
"Very personable, down to earth, reassuring about my issues. They were on time with my appointment and everything was explained clearly."
"Dr Sperling makes every effort to provide the best care possible for his patients. Austin Gastro has the resources and focus to provide quality patient care"
"Dr. Sperling was very attentive and asked a lot of questions to get to the heart of my problems. I would highly recommend him to anyone suffering from stomach issues like I was. Great bedside manner"
"Dr. Duddempudi is extremely knowledgeable and has been an amazing partner in my health care. She has given me compassionate care when needed and straight forward answers when that was called for. I feel lucky to have her on my team!"
"I have been seeing Dr. Havemann for several years. I was referred to him by one of my Dr's that is also a patient here. Dr. Havemann is excellent. He is definately up to date on all the latest treatments and procedures that apply to me. I always feel well taken care of. He also always takes the time to answer any questions or concerns that I have. I now live quite a way from his offices. I can't imagine using someone else so I make the drive.🙂"
"Dr. John Tsai is an incredible doctor that listens and educates his parents. If you are looking for a doctor that is not going to give you a pill to correct your problems this is your doctor. He takes the time to understand you, understand your issues and formulate a mutual plan to address your issues. I highly recommend Dr. Tsai for he is professional, patient, kind and incredibly versed in his craft!"
