Reviews
El Dr. Domínguez es un gran Dr. después de andar con muchos Doctores por muchos años sin ningún alivio, el Dr Domínguez pudo hacer que yo tuviera calidad de vida. Además es muy amable y con mucha calidad humana.
Dr. Dominguez cured my EoE! From my very first appointment, he accurately diagnosed my condition and developed a clear plan for my recovery. He and his team were fantastic to work with, navigating insurance challenges to ensure I received the right medication. The treatment worked faster and better than I ever expected. I’m incredibly grateful to Dr. Dominguez and his team!
My father is a patient of Dr. Dominguez. I met Dr. Dominguez the day of my fathers endoscopy. He explained everything to me and answered all of my questions regarding my dads findings. Unfortunately my dad had his biopsy during the holidays so knowing his results felt ETERNAL but Dr. Dominguez kept communication with me. His medical assitant Crystal is amazing. All of the questions regarding his upcoming appointments, results, and referals, she helped with all of that. I felt so bad the amount of times I reached out but she was so kind and always got back to me. I noticed a lot of the reviews mention how it is hard to communicate to front desk, but usually when you do reach the call center they always get back to you. I whole heartedly recommend this place and especially Dr. Dominguez. Also, the biggest thing for me was that Dr. Dominguez speaks fluent spanish and that was amazing for me since my parents do not speak english.
Great experience with Dr. Krill and his team for my GI care! Communication, details, what to expect, and procedure follow up's were all tier service level. Dr. Krill was involved in every step of my care and provided clear understandings of the process and results. Highly recommended for any GI needs within the greater Houston area!
Dr Krill was GREAT! Very personable, took time to answer all my questions pre and post procedure. He was even very quick to call me back on a follow up question. Super impressed with Dr. Krill at every step.
(Please Note: This is a copy of my review for Digestive Health Associates as it predominantly highlights Dr. Krill.)
I have read some of the comments about difficulties with the administrative staff and will address this later. In general, I call the front desk staff of medical facilities "gatekeepers." And they will make or break your access to your doctors!
To give you some context: In my experience, I needed approval from another specialist to get a colonoscopy. This other specialist had a horrible front desk assistant who lost my approval form, claimed the doctor doesn't complete such forms (after I had just left his office, and he had agreed), and she ignored the doctor's follow-up orders and instead chatted with the nurse for 10 minutes about nothing. Then she left me in an empty office when she took off to NOT do her job. It was dark and almost 7 pm by then. Because I felt something was weird about her, I took a picture of the doctor's follow up orders and approval notes. It served me well.
Now, for Dr. Krill's staff. Yes, one of the front desk ladies is impersonal. I noticed that on my first visit.
After I finally went to the other specialist in my attempt to get an approval letter, I did run into difficulties trying to explain the events that happened with Dr. Krill's staff. His staff did hear my messages, but it was confusing. I explained the situation and it was hit or miss on whoever I managed to get on the phone or whoever tried to get back to me with a voicemail. I didn't get anywhere.
So, this is the impressive difference. During my first meeting with Dr. Krill, he gave me a method of contacting him directly if I ever needed to. How many doctors do that? It's rare. I kept the information and months went by.
Once I had the referral issue with the specialist's staff refusing to write my approved referral, after struggling for about 2 weeks, I directly contacted Dr. Krill. I'm shy and really had been hesitant but by this time desperation triumphed over timidity. I reached out to Dr. Krill. The very next day I was scheduled.
I don't know him very well, but I could tell he was special during my first visit, and he seems amazing. I haven't undergone the procedure just yet, but I'll think about providing an update.
(Note: Please don't use this story as a license to spam and message the doctor repeatedly. The man has a job to do. It is important to practice the heavenly virtue of self-restraint :)...)
UPDATE: I finished the procedure and everything was GREAT!!! I haven't slept under deep sedation since my wisdom teeth extraction as a teenager, so I was overly nervous and successfully delayed the procedure for a year or more. In retrospect, Dr. Krill and the entire staff were the best I could have asked for. Everyone was caring and gentle. I went to sleep, woke up, and everything was done!
In reality, the hardest part of the overall process is the 24 hours prior to surgery at home. Drinking the medicine (I called it "poison water") and staying up practically all night is the hardest part. The "poison water" is rough to get down and you have to do it twice. I'm also not a fan of liquid diets. It's a difficult 24 hours.
Once I was in Dr. Krill's hands and with his staff, everything was easy. I followed up with a Hopdoddy Mother Nature Burger and Parmesan Truffle Fries reward and then resumed my healthier diet thereafter. Everything ended with me HAPPY!!!

Doctors and staff are great at DHA but...have you ever tried to schedule an appointment with DHA? Here is what you need to do. :( First you call the number on their website and then a lady answers and gets all your information and then she checks if any "scheduler" is available, you wait, wait and then wait and then she says she will transfer you to her "scheduler". Then you get connected to a 'scheduler" line with a music in the background as you wait until another lady answers. This is not acceptable. Also, their webpage patient portal does NOT work as this website needs a big improvement to be in line with the digitization of the new era.
Dr. Dominguez is a wonderful physician. My colonoscopy and endoscopy were completed by him and the whole experience was as pleasant as it could be under his care. He was thorough in his explanations, listened attentively to any concerns I had and made me feel reassured. He has great bedside manner and treats his patients like family. You will get the very best medical care with him.
Dr. Domínguez did an excellent job explaining to me my stomach problems and diagnosing my issues. He is very knowledgeable and able to explain every detail to me about my medical conditions and situation.
His staff at both locations are very friendly and were helpful to me. The entire endoscopy and colonoscopy process and procedures went smoothly. I’m would recommending Dr. Dominguez to my family and friends.

Had a great experience with Dr. Dominguez. He quickly and efficiently found the solution to my health problem. Can’t thank him enough. He always gives above and beyond service.
Dr Krill is very personable and easy to talk to about the procedure and afterwords. He takes the time to answer your questions and doesn't rush you.
Amazing team and fantastic doct

Dr. Dominguez is one of the best physicians I have ever encountered in my lifetime. During my 1st visit with him, he introduced himself and immediately expressed his condolences for a very recent loss that I endured. He heard my every concern and was reassuring and empathetic. His knowledge and expertise is top tier. He knows exactly how he can best help his patients and he’s very sincere while doing so. I am so grateful to have him on my health journey, he’s truly the greatest!!! His staff is also super lovely and very helpful!
I recently had my first colonoscopy with Dr. Krill, and I couldn’t have asked for a better experience. Dr. Krill is a very kind and compassionate doctor who made me feel completely at ease. His team was equally amazing—professional, attentive, and efficient. Everything went smoothly, and I felt well cared for throughout the entire process. I highly recommend Dr. Krill and his team.
Dr. Dominguez & his staff are wonderful! He is the type of doctor that will sit and listen to all of your concerns and address them instead of having one foot out the door and in a rush to get to the next patient. His staff is always super helpful and polite. I've been going here for a little over a year now and am so happy to have found such a caring facility.
