"Everyone from the front desk to the PA was very professional. Answered all of my questions and concerns. I would definitely recommend Dr Poreddy and his team."
"I have been going to Austin Gastroenterology for about 12 years. The staff are so nice and the doctors also. I have always felt safe and confident in their care during my procedures. There have never been any issues. Dr. Ellis is very experienced and a top notch doctor. I would recommend Austin Gastroenterology to anyone needing help and care."
"The only problem I ever had was getting a timely appointment, seems the doctors are usually booked up. However a physician’s assistant is usually available."
"The office staff members were very polite and efficient. Elizabeth Bishop took time to listen and explain things thoroughly. I felt very comfortable and confident with her recommendations. The only thing that was frustrating was trying to get someone on the phone to set up an appointment."
"My wait time was about 10 minutes. The staff was friendly, professional and courteous. Ms. Bishop was attentive and answered all of my questions. I was well cared for medically, as usual."
"Good people but too busy. It takes too long to make appointments. It took over two weeks to get my initial screening and almost three months out for a colonoscopy."
"Excellent care from pre-procedure visit to colonoscopy. Every employee was hard working, patient focused, and extremely kind. Dr Ellis was amazing. They run on time and explain absolutely every detail. You will feel extremely supported!! Highly Recommend!"
"I was welcomed by the receptionist with a good morning and a smile. All the stuff did the same. Dr. Elizabeth was very pleasant to work with she was just a jewel. I will be returning. PM"
"This office has always been there for me and that is why I have come back to this office. They helped us keep my colitis under control and I want to say thank you to all."
"Great experience at Austin Gastro. Everything was explained well and the Round Rock location even has a pharmacy on site for picking up your procedure related prescriptions."
"I met with Elizabeth and found her knowledge and professionalism exceptional. She has an amazing ability to explain what was going on with my body with such clarity that I had a calmness that I had not had before."
"Very professional. I felt like I was very important to the staff. I was very comfortable and everything was explained to me in a way I could understand what was to take place in my upcoming procedure. Thank you all!"
"I have been going to Dr. Stassen for many years and for the past few times I saw his PA Katherine Roehm. She is very thorough as Dr. Stassen. I felt well taken care of by Dr. Stassen, Katherine and their team at the Wyoming Spring location."
"Elizabeth Dr Zieberts PA had an in depth conversation with me. Answered lots of questions. Discussed my accelerating problems. Between us, made a plan to address how to progress. Good."
"Very professional. I felt like I was very important to the staff. I was very comfortable and everything was explained to me in a way I could understand what was to take place in my upcoming procedure. Thank you all!"
"My experience as a patient of Austin Gastroenterology has been absolutely outstanding. Making my consultation, my PA Katherine, scheduling with Kayla, Dr. Stassen and his staff and the entire procedure experience was handled with competence, professionalism, empathy and kindness. This practice makes each patient feel important and valued. I am so very grateful for everyone who has cared so wonderfully for me as a patient. This team is the best of the best!!!"
"From the moment I walked in the receptionist was extremely nice. The doctor explained everything what to expect on the procedure and since I’m diabetic advised what to drink in between since I can’t eat anything solid. The appointment to schedule my colonoscopy was very easy to schedule as well. I really recommend this location for everyone who needs to get a colonoscopy."
"Dr. Stassen and his staff are great. Going to miss Dr. Stassen when he retires. He said some comforting things to me after my son died that was above and beyond and had nothing whatsoever to do with a colonoscopy or endoscopy. I'll never forget the words and compassion. You certainly don't get that from these doctors coming out of med school these days."
"Dr. Ellis and the team which worked with him were very personable. They all introduced themselves, Justin, Dr Dry, Maria, Amanda, and April and explained their role in the procedure. Jessica walked me to my car where my wife was waiting. Even a pre-warmed blanket!"
"Dr. Ellis is exceptional. He's been my doctor for GI issues for over 20 years, 4 colonoscopies and two separate surgeries for other problems. He is always professional, proficient, and friendly. He took his time and answered all my questions. it was an office visit is like it used to be with your family doctor, kind of like a Norman Rockwell experience. Because I've been going to him for so long I asked him how many colonoscopies he has performed. He answered 70,000. I doubt there are many with more experienced than that."
"I have been with Dr Ellis & his assistant, Kara along with this group of doctors, nurses & staff since the late 1980s when GERDS was entering my life. Everything that I needed they have been able & most willing to get the problem under control so I could live with it. Dr Ellis & Kara act quickly should my problems flare up which happens only occasionally. My good friend, MJ who is also a patient, had recommended this group to me. Isn’t it nice when you trust a friend’s advice & never regret taking it. Once you visit this group & experience their concern & desire to help you, you too will never regret coming. It is true they will know you from inside out but that is just them being through."
"Dr. Ellis is smart, frank, informed and sometimes humorous. For me, those are winning characteristics. Alert! Drs are not generally my favorite breed of Cat."
"Dr. Vijay Poreddy and Tara Conley are the best doctors for my health they are very attentive with details and carefully take care of everything I need. They also explain very clear. I recommend them as good and professional doctors to my friends."
"I saw Dr. Duddempudi when I had a gallbladder attack. Not only is he knowledgeable, but he made me feel at ease with how funny and friendly he was! And that's a big deal to me, since most doctors feel really clinical and make me nervous. He was extremely accommodating when I asked him to streamline the process of having my gallbladder taken out, going so far as to text the surgeos he referred me to in order for them to see me ASAP. You can tell he makes every patient feel like they're a priority even though he's probably very busy. Very charismatic, super cool, 10/10 for sure!"
"The office has a good appearance and good atmosphere everyone was very polite. The doctors assistant was very attentive nice and took the time to explain the hospital findings to me. Thank you Dolores"
"Dr Stassen is excellent. He has great experience and balanced treatment philosophy. He listens and answers question. I have a technical mind, and he patiently discusses details to my questions. He supports me to be a partner in all decisions. He has been my GI doc for over 20yrs. He literally saved my life more that once, including by identifying a cancer issue on an ER visit CT taken for an unrelated condition, which was not pointed out to me by the ER. He has been patient on not pushing surgery, prior to me trying less invasive treatment. I feel like his balanced approach has allowed my quality of life for the last 20 years to be much better that if I had a different GI doc."
"Dr.Ziebert was awesome with me and my family. He actually listened to our concerns about what is happening with me and my stomach issues. My daughter is a speech therapist and has worked with patients like me. She had lots of questions and lots of thoughts about my condition. He patiently listened and diagnosed a plan of tests before beginning a plan of treatment. We highly recommend Dr Ziebert."
"Kara Skelton, PA is awesome. She listens and she really cares. I've experienced other MDs and PAs that didn't help me at all. If fact others have realistically messed up my life. Not Kara, she has always been an "above & beyond" PA. I applaud her."
"Everybody is very friendly, caring, and helpful. Dr.Ziebert and all of the staff are wonderful. I have been to Austin Gastroenterology several times."
"Dr. Godell is great! He takes the time to listen to you and answer all your questions. He is patient, kind and respectful. The entire team and staff are awesome. Friendly and helpful. Fast replies through the patient portal or via calls. Highly recommend!"
"Dr. Duddempudi has amazing bedside manner. I felt that he listened to all my concerns and was not dismissive to what I had to say- answered all my questions and made me feel that he really cared. I highly recommend him."
"Sheila was amazing! She listened and thought of appropriate action to ensure I begin to feel my best ASAP. Also, they got me in really quickly - unlike the other offices I called!"
"I’ve been going to Austin Gastro for about 15 years. The staff, doctors, and facilities have all been welcoming and knowledgeable. I would recommend them to anyone in need of a gastroenterology doctor."
"Dr. Ellis and his team are professional, friendly, and take the time to talk through health concerns. I have never felt rushed and he has always patiently answered whatever questions I had."
"Dr. Godell is very professional and an excellent doctor. He has been able to help with all my problems and has many years of experience. . He is very personable and an excellent listener. I asked him if he liked his job and he said he loved his job. I wouldn't trust another doctor to identify colon cancer. He saved my partner."
"I love Dr Kosc at TX Oncology. The infusion clinic is large and always has room for speedy appointments and the nurses are all so sweet. Thank you for all you do. ❤"
"I'm a new patient and I was impressed with the lobby, and the speed they had of calling you to the back. When I got to the back to meet the doctor he was very professional. This is the place I picked didn't know anything about but I'm going to keep as my gastro problems."
"Julia communicates the issues very clearly, and listens to you as well. I was presented options and understood the plusses and minuses of the options."
"I wanted to thank Diane, for her assistance today, in figuring out whether or not the anesthesiologists at the hospital were in or out of network . I had spent a good three hours getting bounced back and forth from the hospital to my insurance, to the anesthesiology provider, and back to Austin Gastroenterology, with everyone pointing at everyone else to provide an answer. Diane, understood the problem, and took action to find me an answer. She went above and beyond to take care of me. Take care of this lady, she is a real asset to your organization."
"I will highly recommend Dr.Duddempudi to anyone who is looking gastroenterologist Austin, he is very understanding and thorough, I had a good experience and I will still use him if I have too."
"I had an appointment with Dr. Zeibart. He was great. He explained the procedure and answered all my questions. He wasn't rushed, but made sure I understood everything. This is the 2nd time I have seen Dr. Z, and I highly recommend him."
"Dr Duddempudi is the best Gastroenterologist I have ever met. He is so patient. His positive attitude induced my ability to clearly explain my symptoms to him, and his kind words built a rim of hope within me. I will not hesitate to recommend him to my friends and family."
"Dr. Duddempudi is one of the most attentive, thorough and knowledgeable doctors that I’ve had thus far. He was my doctor years ago when I leaved in Austin and even after moving to Houston and returning, I made sure that I went back under his care. Despite my health being a complicated situation, he is dedicated to figuring out every test, work up and medication that I need to rectify my health issues."
"Sheila knows a lot and answered a breadth of questions. She is friendly, attentive, and patient. I trust her expertise and collaboration with Dr. Glenn Robinson to make sure I am in good care."
"Fantastic responsive staff. Any questions or concerns answered at the latest by the end day of the call if not sooner. Dr D takes his time for a thorough examination and discusses the treatment in clear concise terms. Hes also a very nice person lol. As a Registered Nurse, I highly recommend Dr D. I have worked with him in the operating room and as his patient. I hold him in the highest regard in his speciality and profession. One of the best ."
"I’ve been with Dr. Ellis over 15 years. He’s still the same from day one, very happy, personable and concerned. The process at the Surgical Center was professional, efficient, timing right on and caring Staff."

"Dr. Duddempudi is a top notch! Not only he is very knowledgeable in his field, he goes above and beyond for his patients, which I wholeheartedly appreciate. Thank you!"
"My PCP recommended I see Dr. John ZIebert. His office promptly gave me an appointment. Our 1st. meeting was great. Dr. ZIebert is professional and caring. He asks a lot of questions and takes notes - NOT on a PC. HE GAINS YOUR TRUST."
"Over all best experience of past procedures. I liked the improvement of the prep process. Even though not great the taste of the prep drink it self was much improved. Time getting in and out of procedure has improved. Office personnel were over the top helpful and nice."
"Finally a physician that actually listened to what I was saying and heard me and understood everything I was going through and said to me will get this fixed instead of running around in circles and blaming my condition on something else that I had wrong"
"Thank you for your quick response. 😁 I am very pleased with the care they took to respond to my concerns. Thank you so much for turning this experience into a positive one. The doctor has eased my concerns about my condition and answered all my questions. I'm looking forward to continuing as a patient with Austin Gastroenterology for my medical condition."
"Dr Ellis is a great doctor. He is thorough, personable and provides time for you to ask questions. His PA, Kara is exceptional and her follow through on concerns, testing, etc is what I need. Overall, Austin Gastro is a great practice with staff that is professional and patient-centered."

"Sheila was very helpful and friendly. I felt comfortable discussing my problem with her. She is very knowledgeable and I'm sure she is a great asset to Dr. Robinson. Thank you Sheila!"
"I was very pleased with Dr. Zeibert. My husband went to him first and then I saw him. I thought I was due a colonoscopy, however Dr. Zeibert said by the looks of my chart, I could wait another 5 years. He could have kept quite and performed a colonoscopy just for money, yet he was very awesome about putting the patient first. I would highly recommend Dr. Zeibert."
"She was very attentive and reviewed my chart thoroughly. She answered all my questions and was sure to tell me when I needed to come back and what to expect. Great experience !"
"Great experience from check in to check out.Dr. Stassen was wonderful. Appreciated that the walked me through how to schedule the follow up visits and included my portion of cost. Highly recommend"
"I’ve been a patient of Dr. Ellis for about 10 years, he has a great bedside manner and is very proactive in providing explanations and information related to my medical conditions and recommended course of action. He has a very good sense of humor and makes me feel both comfortable and at ease while discussing my medical issues."
"Dr. Ellis is an amazing doctor when I went to him in 2015, that's why I made it a point to go back to him in 2019. They were able to get me in before my scheduled appointment due to a cancellation. I had a abdomen ultrasound and his office called me within an hour or two of me having it done. Unfortunately I still had to get the endoscope done but everyone was very friendly and it took no time at all. They called me with my results a few days later."
"Dr. Robinson takes the time to explain everything very well. He answers all questions fully. The office staff is very friendly. If you are having any gastrointestinal issues, I highly recommend this group."
"Since last month, I have been undergoing treatment with Dr. Ellis! Part of my care has included his PA, Kara and Medical Assistant, Stephanie. Simply put, I feel valued and attended to due to their watchfulness! Also, their communication has been effective and congruent. So, due to their consistent follow- through of my medical care...... I AM HEALING!"
"I went, I listened and now I am at the wait and hold to see if there are adequate results. I found the doctor informative and he gave me an alternative which had not been explained to me before So I will wait and see if I have results if not I will MoveOn my original action. This particular doctor was forthcoming and I think he shared what he truly believed. He was not invasive and did not seem to desire to rush into surgery. I appreciated that."
"I was referred to Austin Gastroenterology by my OB/GYN! I have been to Austin Gastroenterology's Wyoming Springs/Round Rock office twice, received emails, phone calls/voicemail messages and written communications and every aspect of the above has been a stellar experience! This practice has a exquisitely fine-tuned operation and the most important aspect of their practice is the wonderful, personable very professional support team!"
"Jessica and Dr Stassen are very personable and genuinely interested in both wife's and my health wellbeing. We have been patients for close to 20 years and will continue with them. The team at the Shoal Creek colonscopy/egd facility they use have always been courteous and professional. Kudos"
"I found the staff at Austin Gastroenterology to be friendly, knowledgeable and very professional. Having been in the medical field for 28yrs, much of it as a medical assistant, I felt I was in excellent, caring hands. Dr Ziebert is fantastic!"
"Dr. Ellis is very professional and makes you feel comfortable as soon as he walks in. Very knowledgeable and up to date with technology and current practices."
"Confidence and professionalism are two descriptions I have for William Stassen. Do the preventive colonoscopy for your health- and trust this doctor.. experienced and thorough."
"I’ve been a patient with Doctor Stassen for 17 yrs & Jessica has been his PA for many of those years. I’ve always received top notch medical treatment & care from Austin Gastroentology."
"Dr. Godell and Dr. Solimine have been absolutely incredible to say the least. Kind, understanding, and extremely helpful beyond belief. Changing my life to be honest."
"Elizabeth Bishop, Dr Ziebert’s PA, is a delight to work with. She really listens to what you say and has very intelligent, informative feedback and suggestions regarding your treatment. I like her as much as I like Dr. Ziebert (which is a lot!) and am very comfortable seeing her for anything I would see Dr Ziebert for. They are both on the same page, and they really make a good team."
"Oh my goodness, I didn't expect the treatment that I received. Everyone was so friendly and helpful and it started with me trying to navigate the portal. Dr Ziebert was very thorough with the questions that he asked me, he came up with a plan for me and gave me a sample because I couldn't afford it. Thank you Austin Gastroenterology."
"Elizabeth is excellent at her job. She is highly knowledgeable, and does not patronize She has a great sense of humor that put me at ease. But at the same time was serious and answered my questions and concerns very professionally."
