I am disappointed in the service I got. First let me start by saying that just because you are…read morepaying for service "Out-of-Pocket" does not mean that you should be treated differently. I had a GI bleed a month prior to coming to HGI (Houston Gastro Institute) for a follow up. I was scheduled for two procedures, an EGD and Colonoscopy. I paid in full out of pocket almost $2,800 which was not the original price they quoted me at consultation. Nevertheless, it was paid. I then prepped correctly the a day and a half before scheduled date. My wife and I were the first through the doors besides employees at 8:30am. We waited, and waited , and waited till there were 4 couples in the lobby before they started calling people in the back. It was now 9:30 and 2 clients went to the back to start their prep. It was 9:50am when I was called to the back to prep. It took 28 minutes for someone to talk to me after changing into my gown, then 45 more minutes till I had an IV put in. As I watched 3 clients complete the procedure I realized the time was 11:08am. I asked when are they gonna start because I was extremely uncomfortable. 15 minutes later a great lady said that she will be taking me back in 15 more minutes. Very close to 11:40am was when I went to the back and put under. A little after noon I was being wheeled outside to my waiting wife whom had no idea what was taking so long. A few weeks later I get a bill in the mail stating that I have a remaining balance and I need to be paid. I tried to call HGI multiple times with no answer. I had enough and drove 45 minutes to the office to find out what why I still had a bill. THE FRONT DESK PEOPLE should work for Walmart because they don't care. I asked to speak to someone about the bill. The guy asked me why and I said I would like to have that conversation with them and not in an open lobby where they don't care about HIPAA. I then asked what Herbie thinks the meaning of HIPAA means that's when he got upset and went past the glass doors and started talking freely about why I wanted to talk to management. After showing the same person I paid the full about the bill I got in the mail, she called another company to see why. We got made sure that the bill was a complete mistake. I had a followup visit a few days ago and I confirmed that I was going. My wife went out of town and I became very busy with work and couldn't make it. I tried to call 4 time to tell them that I cannot make the appointment. No answer. I Live on the west side of Sealy, TX, which is 45 minutes from my house to HGI. Needless to say I did not go to my appointment. the weekend went by and today Monday the 14th of April, 2025. I got a text message stating that my account will be charged $150 because I did not show for the appointment. I drove to Katy and stopped by HGI to talk to the about the charges and also have a copy of my records. Same two front dest employees. While talking to the lady, the male was just looking at me. I didn't say a word to him. She told me that to have my records I'd have to pay $25, but to send it to another provider it would be free. $25 for my records. Just unbelievable. I will NEVER go back!! They got paid but I will make sure to tell everyone I know to go elsewhere. Look at all the 1 starts they have.

I've been here twice with my mom. Her doctor is Dr Vivian and I really just hate coming here. The…read morewait times are ridiculous. We are currently freezing in the examination room for 45 mins and no doctor. This is after waiting 30 minutes in front waiting area. I went out to ask what is the hold up and the assistant stated she needed 10 minutes to give me status!? Avoid this place if you can. I'm going to find my mom a different gastro, if you can't control your schedule I doubt you can keep up if time sensitive treatment comes up. Not a fan and will avoid this place. Update: We waited for about an hour in the room for the doctor. No doctor ever showed up. No apology for time wasted and complete disregard for the patient. I'm glad I went with my mom, she is the type of person who would just have waited hours on end. We are paying these doctors for service and they owe you respect for your time. At least they gave her a refund for her copayment. 0 stars and never again.

Since this whole summer has been me dealing with being sick, I figured this would be the perfect…read morereview for my 500th! My regular gastroenterologist referred me to Dr. Desai because I guess I have unusual anatomy. I went in for an ERCP but my regular gastroenterologist couldn't complete the surgery and called Dr. Desai to come in and he suggested he try and do the surgery again later that day. I loved that he sat and explained everything that happened and would happen to me and my husband and even allowed my husband back in the surgery room for a few minutes as he knew I was pretty nervous. My husband said while I was in recovery he came out and explained again what he did and actually gave him his direct number with any questions we might have later. Fast forward a couple weeks and I went back to see Dr. Desai as I still wasn't feeling well and he suggested another surgery but he explained everything and why I needed it and totally calmed my fears about everything. He has a wonderful bedside manner and really listens to you and answers your questions in a down to earth way. The office is convenient for me too, located on Blossom in the same building as my primary care doctor so that's awesome! I also adore his office staff! They are so friendly and they get stuff taken care of! I was going to a different gastroenterologist and I like him ok, but I'm not going back to see see anyone but Dr. Desai now!

I was sent to this facility on a referral from my primary care doctor. I was assigned Dr. Bala. I…read morewaited over an hour past my scheduled appointment time. I found him to be quite rude. He would not listen to me. I tried to explain to him that I was sent there on a referral for some very severe problems. I explained to him what I have been doing the past two weeks. He basically told me to go home and keep doing what I was doing that I would be OK. Are you kidding me? If you don't have Covid you don't exist in the world right now. I wouldn't recommend this physician to my dog.
