"This was my first visit and I really liked the doctor’s positive caring attitude. I could tell she loves her job. There was no rushing and she listened to my concerns."
"Staff was great and friendly. I only had to wait like 15 minutes after my appointment time the iPad they gave me for my medical history. Didn’t save anything that I inputed so that was a little disappointing. overall, great place"
"My husband, Don, was thoroughly happy and impressed with all the DHAT staff (Kristie L. Blank, MD) on all levels and the care he received. Thanks to all of you and all you did."
"First visit to the office. All of the staff were very professional and welcoming. Also, I appreciated the time they took in explaining every detail and listened to my concerns as well."
"I appreciate that they able to have someone get me into the office quickly. Those providing my care were professional and attentive to my concerns. Once I met with my provider, I felt much more at ease as I left the office. Well done."
"Wait time was very short, less than 15 minutes. The PA reviewed and explained the pre-visit questionnaire and answered all my questions about the upcoming procedure."
"Mark Miller's PA for my follow-up. She was very good listening to my ongoing symptoms. She ordered 2 test for me. September 16th & 17th. I had to cancel them do to me catching COVID! I took my last dose of the COVID medicine today. I will wait 48 hours and test again. If I'm clear I will reschedule with them."
"Caty is such great person, attentative, helpful, professional, goes out her way to accommodate people....I want her to always take care of me She is like family to me!"
"They were very thorough and making sure they went through all the steps to hear me out as well as to set me with the right plan to make sure that I am being treated and diagnosed properly everyone was so nice at the facility."
"The staff at DHAT Rockwall are caring and wonderful people. In particular, Iselyn Bueno and Mashaer Rajan are exceptionally committed to the care of their patients. By way of example, My Son was diagnosed with Hepatitis C and was prescribed a medication that is approved for use by his insurance company (Blue Cross Blue Shield of Texas), but during the pre-approval process, BCBS would not approve the use of the medication. It took 3 months of appeals, peer to peer reviews and many phone calls from Iselyn and Mashaer, before BCBS finally relented and approved the use of the medication. Without the extreme persistence of both Iselyn and Mashaer, my son would still be untreated. I was quite surprised that these wonderful professionals were willing to spend months fighting on behalf of their patient and ultimately won the battle. It's a sad state of affairs that very busy health professionals have to spend months of their time fighting insurance companies instead of providing care to other patients in need. My sincere thanks to Iselyn and Mashaer for going way beyond the call of duty for my Son. Also, thanks to the other good people at DHAT for the wisdom and foresight to hire dedicated professionals."
"Dr Sarles is sweet kind and cares about the patient. We did not chit chat about the weather I was sick and he fixed it. I am 76 so we do have problems as we get older. My surgery was so pleasant. I didn't have a Major one but enough to scare me Over done a d we t home with no cplications,pain ."
"My visit to the office was fine. It was my telephone call to renew my medication. Left messages no call back. Called front desk to talk to someone. Long story short, we were on hold for 45min. And she didn’t want to help me until I had to get ugly with her. Don’t like that kind of service. Don’t expect good phone service , it’s not at this office!!"
"I met with Mashaer, PA to review my health concerns. She was extremely thorough in reviewing my medical history and answered any questions that I had. I appreciated her professionalism when working with me. Thank you!"
"Would like to see a sooner follow up visit than over 2 months away. I have some issues going on that I will have to endure then longer than I think I should."
"My visit was a really good one. From the front desk to my meeting Dr. Jilian Sarles for the first time! I did not have a long wait, and everyone was attentive to me as a patient, and really nice! I felt that my medical issues were important, and well taken care of, and in a very timely manner."
"Wonderful experience. Dr. Really takes time with you to explain what’s going on. They listen to the patients concerns. From front desk check-in to check out. Very friendly and professional. Wouldn’t go anywhere else for my GI issues."
"I love Dr Miller and his assistant Jennifer. Oh and his nurse Brianne. They are so kind and listen to all your issues and give you choices on how to fix it. The only bad thing I can say is it takes over a month to get in to see them, but that just proves how good of a doctor he and his staff are."
"They really handle their patients in a courteous, yet professional manner. Very timely to your appointment. The PA was kind explained my situation to me clearly and how we needed to move forward. I would definitely refer my family and friends to them."
"Jennifer, the Doctor or PA was amazing. So sweet, so full of information which she explained well. Jennifer the scheduler was super nice also. She got me in quickly. The front desk ladies were super friendly and very helpful. The whole experience was nice and comforting."
"Dr. Seif is always professional and caring. Office staff is professional. I’ve been going to this office going on 15 years and wouldn’t think of going anywhere else."
"All of the employees that I interfaced with were very nice and helpful. My wait to see the doctor was very short and my visit with the doctor was very good. He gave me a lot of good advice for how I can get my health problem resolved quickly."
"Jennifer Lambert was great. She understood my digestive issues I was having and gave me a plan of what to expect next. She answered all my questions I had, and It was a pretty quick visit."
"Dr Sarles is simply the best. Julian is a wonderful person, she listens well and always want to help get yourself feeling better. Both are family to me"
"The staff is so professional. Dr Sarles is to the point and takes the necessary precautions that I feel are appropriate..I feel very confident in the doctor."
"great doctors and staff. If u want excellent care & a doctor that really cares about u Dr. Sarles is the dr. u need. I had gone for years without any answers to my problem & no diagnosis. I saw him one time in Aud. 2022, he ordered a colonoscopy & made a diagnosis & gave medication & I have been doing great ever since. He is # 1 in my book."
"My experience was great,they explain everything to me so that I could understand and I felt very comfortable with Dr lambert and I would refer her to ant other person that needs the help like I do."

"Grateful for this team to answer and take time to explain things I have questions about. Never feel rushed or a number in the schedule. Highly recommend anyone in this office."
"Everyone in this office is amazing! They have helped me so much with my acid reflux! Yesterday I saw the PA Julian and she very patient and listened to all my concerns and really helped me out!

"Dr. Sandoval listened to me and my concerns. We made a plan together and he answered all of my questions and concerns. The nursing staff were super nice and attentive they gave me all of the information I needed from my visit."
"The office is very ptofesional. Appointments are very timely... practically no wait time. Dr. BLANK and her PA are very attentive to patients. Great place."
"Long and detailed-First, I’ve been nursing for 17 years. I’ve worked many places, including a pediatric clinic. I am writing this as a mother who happens to have experience with healthcare. I purposely made my daughter’s appointment just after lunch, and I had all needed items (insurance card, ID, etc) ready. Paperwork was easy and not overly time consuming. We were in the room within 20 mins. I try to be very thorough when explaining issues, and both the nurse/medical assistant and Dr Chan listened and responded compassionately. My biggest praise-my daughter is 15. I nurse at a school of 1-4th grade, and I’m constantly telling people I have to talk to the child as much as possible, not through an adult. Dr Chan politely told me she would be discussing as much as possible with my child, and only asking me the things she couldn’t answer. I could not have smiled harder; in my child’s eyes, her pain and issues were validated by her specialist at that moment. Dr Chan is very thorough and explained a plan of care to me and my child. My 15 year old absolutely hates needles, but with the lab 1 door down we were able to get it over quickly and the phlebotomist was extremely nice. The X-ray was right across the street and took about 30 mins on a walk in appointment! All in all, we had a detailed initial appointment, lab work, and a X-ray in less than 2.5 hrs. I was able to check the portal and since the appointment was on Friday, the X-ray results were added late Monday. The lab results had not been added, but Dr Chan has emailed several times through the portal checking on my child and notifying me of results up to this point. She is polite, patient, and professional. If I worked clinic again, from this side of the room I’d gladly work for her. I will (and have already) recommend her for any pedi GI needs."
"Dr. Chan is incredible. When your children are sick, you want the best. She is that for us. She has such a calming presence and bedside manner. My child was comfortable talking to her and getting examined by her. I hope your kid never has to see a specialist, but if they do, she’s a great choice."
"I am happy I am taken care of and treated well. Kristi Blank and her assistant take the time to listen to me and ask questions to make sure my needs are met. They don’t just prescribe drugs and say bye. They spend quality time with you and help work through your issues the correct way. I love the friendly environment, it’s super clean there and smiles all around making you feel welcome."
"I rated my experience 5 stars because on Monday 3/28/22 (my birthday), i underwent 2 medical procedures in the hands of a 5+ star medical team. Doctor Sandoval was exceptional. He was very personable and made sure I fully understood the who, what, why where, when and how 🤔 of the procedure. The nurses and other medical team members were out right awesome. Ashley, the nurse who prepped me for the procedure; given both her personality and medical skills made me feel as though I was in the hands of a medical angel. My experience that day due to the flawless delivery of a medical service by a true team of professionals made a potentially traumatic day for me a very uneventful one. When I woke up in post-op, I initially thought that I was still in pre op. The reason being is that even though the entire procedure in reality took several hours to complete, when I woke up in post-op it felt like to me that only a few seconds had passed. So, kudos to the mixologist, I mean anesthesiologist. I call him the miracle maker and he's earned at least a 5-minute standing ovation. Also, on a final note the front-end people were excellent too Overall assessment- 1) solid communication and 2) excellent delivery of a medical procedures coupled with a sense of a well thought thorough system of patient care. 5 STAR 🌟 Performance Sherman"
"We love Dr. Chan! Both of my babies have reflux, and my oldest had a more complex issue going on. One that I tried getting doctors to listen about for his first year of life. When we discovered Dr. Chan, she instantly picked up on it without me even mentioning it. She knows the right questions to ask, the best tests to run, and the best providers to refer you to if you need additional care. Her intuition, professionalism, and bedside manner are unmatched. I highly, highly recommend her to anyone and everyone. Additionally, her office staff are equally amazing. Courtney and Margaret always get us taken care of super quickly. All around, a fabulous office."
"I have been seeing Dr Sarles for about 5 years & I have moved to Austin but I still drive back to keep seeing hm! Dr. Sarles is an amazing person & doctor. He is so kind & explains everything. Also his PA Jillian is just as sweet & kind for all follow up visits! It was no surprise to find out that she is his daughter! So I highly recommend them!"
"Dr. Jillian has been instrumental in dealing with a digestive issue that I have been dealing with for over a year. Dr Kristie Blank made my first colonoscopy so simple and painless."
"DHAT has been a great experience. Dr. Sandoval and his staff (especially Cindy) were very patient, they listened to my health concerns, asked more questions and were very professional. I would highly recommend going to DHAT if you are experiencing anything wrong with your digestive health."
"DHAT in Rockwall has great systems and staff. The facility had a power outage the morning of my procedure. The front desk staff greeted & checked in patients without access to their computers or phone systems graciously. They made phone calls on their personal phones and accommodated everyone's needs. Nurses kept us informed and doctors made best decisions based on the circumstances. Everyone worked together beautifully. Even though that had nothing to do with my actual procedure, it shows professionalism under stress. Dr. Blank and her associates are professional, efficient, and have historically been my "go to" GI. From pre-op to post-op, staff treated me as if I were their only patient. Highly recommended. Thanks everyone!"
"I have always had complete confidence in the medical professionals at digestive health association health association. Doctor Miller and his P a's are great.. But I have had numerous problems with the office staff. Recently was at my last appointment but but the new office manager came in and spoke with me and she understood my concern and was going to address it address it. I left feeling totally confident that she would take care of the situation and that I would not be put through through that lack of infantry again Kudos to the new office manager"
"Great experience with Dr Miller and all the staff working there. Clean facility and COVID precautions in place. By the way the nurses do an excellent job taking care of you after your procedure is over."
"I was extremely impressed with my new patient visit today. Doris was incredibly kind and put me at ease. Additionally, Chris was very thorough and worked with me to find a personalized solution. I usually dread these visits but no longer have to. I highly recommend DHAT Rockwall and all of Dr. Sarles staff."
