The DHAT facility was very clean and all of the staff was friendly. Cecelia helped me and she was very friendly and thorough. She even brought me a warm blanket. Nate was the nurse anesthetist. He explained everything thoroughly and he and Dr. Maddala made me feel safe and comfortable . I would recommend Dr Maddala and DHAT anytime.
Diagnosed in my 70’s with IBS Dr Maddala has been the light of my life and treatment. I thank God that I found her. She is a very kind, caring and knowledgeable doctor who understands the difficulties of living with IBS. She always seems to have a plan for my illness which I now finally understand is lifelong. Unlike many other doctors who have treated me over the years she ALWAYS makes time for me in every appointment to tell my evolving story. I cannot recommend her more highly!
As a new patient, Dr. Mantas was really welcoming and made you feel comfortable in his office. He took his time thoroughly asking questions of my symptoms and making sure all of my questions were answered as well. All of the staff were friendly and knowledgeable!
Dr. Mantas is great and the process was smooth except for the hiccup with the GI Alliance central scheduling team. Had a little mixup there otherwise it was a fairly smooth and efficient procedure.
Great office! Dr. Nayyar is professional, knowledgeable and a great listener. He was very informative and answered all questions I had concerning an upcoming procedure. I know I’m in good hands!
Dr. Lyles is a wonderful doctor with good bedside manner. I loved the staff and Nurse Kirsty!
I originally saw Dr. Mantas in 2022 due to some stomach issues that weren't being resolved. Being fairly young, I felt weird going to a specialty doctor, but my concerns were quickly alleviated by the fact that Dr. Mantas seemed competent and straightforward in his healthcare approach. Now, a few years later dealing with a separate set of issues, I'm glad to be back.
such a pleasant environment all of the staff are very nice
I had a very good Gastro while in CA and I was worried about getting a doctor of that standard when I moved here.
Dr. Raghavapuram exceeded my expectation on every aspect, like his knowledge, professionalism and friendliness.

I was pretty nervous to meet a new doctor, but I found Dr. Sai easy to talk to and left confident about our discussions. He was good to listen and answer any questions I had. I would recommend.
Dr.Mantas and the nursing staff did wonderful job with my colonoscopy procedure and making me feel comfortable.
Great listener, explain everything great clarity, showed empathy, encourages to express my concerns and problems. Amazing doctor!
We saw Dr. Sai for my 80-year-old dad who was having pain in his left leg. Turns out it was due to disc issues that were pinching a nerve. From the moment we walked in, Dr. Sai was super kind and patient—especially considering my dad has some hearing trouble. He didn’t rush at all, listened carefully to everything we said, and explained the condition and treatment in a way my dad could understand. That really meant a lot.
The staff were so friendly and helpful during check-in and check-out.
Overall, a great experience. Would definitely recommend Dr. Sai to anyone looking for a doctor who genuinely cares about his patients.

Dr. Badr is kind and empathetic. I would highly recommend him!
It was very easy to deal with this medical group. They really worked to get my insurance to cover almost all the expense. Dr. Patel is a very good doctor and made things go smoothly.
The doctor is attentive and listens patiently before suggesting an appropriate treatment plan. I highly recommend him for anyone dealing with stomach-related issues.
We have always had a great experience here. Everyone was absolutely amazing.
Friendly, efficient, respectful.
Dr Kumaravel is very knowledgeable, caring and listened to all my questions and concerns. She gave me a treatment plan which is already helping after only three days. I highly recommend her!!
She was punctual, on point, relaxed and thorough. Good communication skills.
Excellent Dr and bedside manners. Definitely recommend him.
I have 2 pre surgery today and Dr. Nurse hospital all was excellent and Dr. Sai was best I seen.
Perfect, everyone was nice, explained every detail and no complications. No problems next day. Woke up happy and satisfied my doctor took care of me.
A really nice person and attentive to my needs. I will be having a couple of tests with her and will follow up with her. She was that impressive. Highly recommended
Dr. Paul Paradiso was extremely professional, has a great bedside manner and wonderful sense of humor. He was thorough in both exam and my procedure.
I have been a patient of Dr. Hall's for several years. Dr. Hall has always listened to what I tell him and has always treated me with respect. I highly recommend Dr. Hall.
The whole staff is very kind, caring and professional! Dr. Youssef listened to all of my concerns and I never felt like he was rushing to get on to the next patient. When I called with questions, I was able to talk to a medical professional and received all the answers I needed. I highly recommend them!
Love the Staff and Dr.Paradiso is so Understanding...and such a nice person...Dr. Paradiso is the BEST YOU WILL FIND!!!! He has help me so much with my Cliac...

Always takes care of my needs.

Always thorough, makes sure you understand what he is discussing. I would definitely refer anyone to him!
Very professional? cared about the patient.
Dr. Sai is very helpful and very comfortable to talk with. He gave me ample amount of time to listen to my health issues and planned my treatment. He went out of his way to be available for me during my urgent need. His front desk clerk including his medical assistant cared about my issue and were very supportive.
Dr. Abraham's office is efficiently and well run! Dr. Abraham listens and is easy to talk to. The staff is outstanding! I would highly recommend Dr. Sindhu Abraham.
I've been a patient for years. Always good service.
Great practice! Friendly, professional and kind. Highly recommend!
My husband saw Dr. Alloju for the first time and was very pleased. He said the Doctor and his staff were very nice and professional.
Every aspect of this medical procedure was outstanding. The team was exceptional starting with the receptionist who reassured me that I had enough time to get from Methodist center to Plano for the procedure.
The nurse, Angela, heard me when I told her it is hard to get a needle into my veins- they are little and roll. After spending time looking for the right vein, she didn't try to puncture me. Instead Angela called Amina. Amina was able to do it after taking substantial time to find the right vein.
This is in stark contrast to a blood draw in January for my annual exam. At an unrelated lab, to get my blood, it took three different technicians and 4 punctures with their needles. One tech said she “blew the vein" and left me with a hematoma. This is the usual experience I have.
At Digestive Health, however, Amina did the successful insertion of the needle without hurting me to hook up the IV bag. then she cautioned the anesthesiologist Lana, about my veins. All of them listened, did not hurt me and the procedure was successful.
I was comfortable with and trusted the physician, Dr. Verna Kumaravel and will seek medical care from her in the future.
I am very grateful for the care these medical professionals took, and their great communication skills.
I wish I could have these nurses, doctor and receptionist for every medical procedure I have !

Dr. Odstrcil is the best GI Doctor who gives her patients extra time/care when needed. She is very thorough and patient.
Just had a colonoscopy & endoscopy done by Dr. Shea. I can honestly say it was a great experience. The whole staff was extremely attentive & answered all my questions & concerns. He made sure I was comfortable & even had music playing when they wheeled me to get the procedure done. I would definitely recommend him.
All the staff was polite especially Theresa
Very patient, explained situation clearly, kind and understanding. I would recommend him!
Dr Thomas Lyles is a very caring & compassionate physician. It is rare to have a practitioner who will listen to everything you say without also entering information into a computer at the same time! I felt valued & validated. We agreed on a plan of care & ended the appointment with a hug! Thank you, Dr Lyles!
I have been able to refer some of patients to Dr. Sidhu! Amazing and very knowledgeable physician!
"Dr. Odstrcil listens and explains options very well. She is very thorough and wants to get to the root cause of any issue. She is patient and caring and spends a good amount of time with you and doesn't rush you. I was seen on time and didn't have to wait to be seen.
Doctor very concerned that patient understand what she is doing and why.
It was my first visit Monday with Dr Nackley. He was so nice, funny & a true delight!! The staff were all so friendly and nice. I look forward to being a patient. Dr Nackley totally understands my needs.
Thank you.
Thank you.

We had an amazing experience.
Dr. Alloju and his staff are friendly and knowledgeable. When you go in for an office visit you are checked in efficiently and kept updated when you will be seen. Dr. Alloju has a great bedside manner and explains things in a way that is easy to understand. He listens to you and answers your questions and concerns.
This was my first colonoscopy. I probably waited too long since I am 66, was a little apprehensive but everything went smoothly. Dr. Paradiso and his team were excellent. No problems.
Dr. Candice Jantz has been an amazing provider! I feel very confident under her care. She is informative and listens effectively to my questions and concerns. Nina and Conn are also very helpful and engaging.
Doctor Nackley is fantastic. He had already checked up on my previous issues from being in the hospitals frequently and gave me wonderful information to improve my problems. He is so friendly and easy to talk to. I am so thankful I found him!
Dr. Maddala is so wonderful. She is kind and very attentive. She goes the extra mile to make sure you get the best care. I searched for another GI Dr. after my previous GI Dr. didn’t really help me and I’m so happy the Lord led me to her. I suffer from terrible GI issues, bloating, gas, etc. I’m just grateful Dr. Maddala saw my concerns and desperation and took the necessary steps to help me. I recommend her highly. 🙏😊♥️
Just consistent good service. Good at follow up and efficient friendly staff.
Dr Blank is so nice and so kind to her patients!
The Dr. was kind and took the time to explain the procedure to me.
Dr Miller is incredible! Very kind and considerate and he takes the time to talk to you. He has a great disposition and great bedside manner that put me at ease before my procedure and afterwards.
Great Dr and great guy!
Great Dr and great guy!
The procedure itself was exemplary. My only critique would be that their office should use a text to the patient to inform them of important information being delivered for review. Since I’m retired, I don’t check my email every day and if I don’t, the email gets pushed down to where I don’t know it’s there. If I don’t know it’s coming, I don’t know to look for it. Also, it would be nice if every once in a while, Dr Blank’s assistant would be present to pick up the phone—- in the name of good customer service. It’s frustrating to ALWAYS have to leave a message.
Dr Chandra and the entire staff are very kind and helpful. I appreciate him.
Outstanding Doctor! He takes the time to listen, and answers with care and compassion. I don't feel rushed. He is a very kind doctor for sure.
Had a great experience would definitely recommend Dr Lyles
Every person who worked with me was absolutely delightful and professional.
Dr. Liles is the nicest, most understanding doctor I have ever met. He is very dedicated to his patients and will work hard to help them. His staff is kind and very nice.
Dr Sanjay Nayyar, M.D., is very professional and an excellent Gastroenterologist... he attentive and provides helpful information that you can understand. I would highly recommend him!
Very knowledgeable and personal. They really care about you and your results. Explains everything thoroughly. I highly recommend.
Dr Madalla is an amazing specialist she is kind compassionate and excellent in the O,R,
Dr. Parasidos and his team were attentive to my needs, very thorough in my treatment plan, polite and professional.
The staff and facility was just great! Everyone was so kind and super thoughtful. I’d highly recommend Lone Star Endoscopy Keller and all the staff there.
I really liked Dr. Patel. He was friendly and took time to explain things to me. I would recommend him to anyone.
Dr. Blank is so considerate and thorough. All at the same time. Her staff are also easy to work with.
Clean office, caring & professional staff! Dr Nayyar is friendly, caring and listened to my concerns. And then voiced his concerns and I listened. I loved that he is aware of the latest developments in colon, gastric & liver studies. I am happy with his plan of care for me.
Doctor Ho was so caring and very informative. Staff was pleasant and organized, making it less stressful for me. I highly recommend this doctor. Made the consultation nicer even though we are talking about GI :)
My visit was very satisfactory.
Everyone from check-in to checkout was so friendly, made me feel so comfortable and knew I was in good hands.
Dr. Patel was friendly, knowledgeable and very approachable. I feel like he really listened to me rather than assuming what I was going through. I would recommend him to anyone!!
Muy atentos las enfermeras y el Dr
Always enjoy seeing Dr Ho. He is so courteous and listens to everything i have to say.
Had a meeting with Dr Hill. As what was expected. Very informative.
I had a great experience. The entire team was excellent and I have no complaints. They made the procedure easy to go through. I have had the procedure at another place but I prefer Dr. Blank’s team is the best!
Good visit. All very professional and courteous.
Dr. Arslanlar is a very compassionate doctor. His bedside manner is great. He doesn't rush the appointment and is truly concerned with everything you are going through. He doesn't give up on finding a solution to the problem. I definitely recommend him.
I highly recommended Dr Bula Chadra! His wisdom, personality and great care for me has brought nothing but encouragement to my life. Often times doctors are busy due to their schedules, but he always takes time for me. His staff is also caring and intentional with everyone that comes in!

Dr. Yepuri is amazing! Knowledgeable, patient, never rushing and amazing bedside manner. 10/10
I had my colonocopy procedure done by Dr. Sai. I couldn't have had a more perfect dr. or process. The office staff setting up the appointments were courteous, kind and professional. The morning of the procedure Dr Sai came to meet me in pre-op and explain everything that would happen and assured me I would be taken care of. Soon after the procedure he came to give me the results and explain the findings. Everything was smooth and stress free. Dr. Sai is compassionate, warm, knowledgeable and professional. I could not have had a better experience. I highly recommend him and his office.
In my opinion she has a wonderful bed side manner, has been a good listener and thorough. She has given me some alternative things to try for my situation. Would recommend.
Great bedside manner and very professional explains everything so you can understand it I would highly recommend
Great experience with doctor, and staff. Clean facility...
The staffing smiles make you feel welcome.
