There has been two times now that they have helped me out when I needed them to, and this last time really caught me by surprise. I'm not going to go into detail for personal reasons, but the PA, administration, and stein himself do care and they've proven it to me yet again. I'm not sure why he hasn't gotten a review, but he deserves it, I would recommend him to anyone else around the Sugarland area if you are experiencing GI issues.

I had a frustrating experience as a new patient with this confusing practice…read more TLDR: Don't waste your time trying to see this doctor for functional medicine. It's a cash only. Practice selling supplements etc. The whole story... I called for an appointment and did a pretty standard intake conversation over the phone. I gave my details, my insurance information and based upon verification was booked with an appointment time that they gave me in 4 weeks to be seen at the Katy clinic. Imagine my surprise when I arrived to my appointment and the patient receptionist told me that I there was no record of me in the system! I was aghast. Not only had I had a 20-minute conversation with someone, I had given a lot of my personal details like my demographic information, health concerns and insurance information! After refusing to let them gaslight me, I was able to look in my records and give them the date of my call as well as verification that I had sent my insurance information by email to them. Apparently no one in the office actually answers the phone, a faceless nameless call center does that work. Somewhere in their convoluted and opaque process, someone took all this info from me, received my email, quoted me an appointment time, and then failed to make the appointment they gave me. The front desk person I worked with was unapologetic for all of this. She seemed to think I should have inferred that because I hadn't been texted any reminders I should have guessed there was a problem. She offered me alternate times without apologizing for the inconvenience or unprofessionalism they had already displayed. When she asked me (again) what my issue was she informed me that I needed "the functional medicine side" and not the "gastroenterology side", whatever that means. One doctor, one practice... It's not my job to know how you guys internally structure your practice and how you segregate patients?? She went on to begin booking the other appointment - a video visit which apparently is the only way Dr. V sees new patients (they didn't tell me that on the phone they made a face to face appointment that I waited weeks for). While standing there and waiting, my eyes caught on a brochure advertising their services which explicitly said that the gastroenterology visits are insurance visits and the ones for the functional medicine practice are "insurance free". I stopped her immediately. It turns out that what I wanted to see the doctor about is their cash clients only part (supplement sales). I just turned around and walked away. I'm super frustrated and angry - I had super high hopes for this practice and instead walked away with my time wasted and disrespected as well as a negative opinion of their professionalism. I'm not in the market for a cash only supplement pill mill, and that seemed to be what they were trying to push me towards. Don't waste your time with this one!

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.

This was an immediate red flag because it told me he was not listening to me and was just there to get the job done and move on. I told him that I was experiencing loose stool, and this was an issue that I did not have before starting a medication, and had ONLY been occurring since I had been on a specific medication. And what does he say? "You need a colonoscopy." You're going to tell me rather than ask me what's the medication, let's research the side effects, let's see what dietary changes may fix this, you're immediately going to jump to an invasive surgical procedure? And we already covered that there was no physical discomfort, aches and pains--and that this loose stool ONLY came after taking the medication I'm on. He just wanted the money he would get for having me do a colonoscopy.

It only opens Tuesdays afternoon and all day Thursdays. I'm back this year with other requests. Again, I purposely requested to see Doctor Shannon. (Not sure why Physicians at Sugar Creek didn't just automatically enter his name in my record.) This time, I went to his main office at Hermann Memorial Sugarland Medical Plaza. Wow. Talk about the distance and traffic that was a breathtaking experience. The facility is much updated. There was plenty of free parking behind the building. There are 3 elevators to 2nd floor. Yes. I drove further than I had to. Why couldn't I just see anyone at Hermann Memorial Southwest Medical Center, which is just down from my house? Because Doctor Shannon is GOOD.
