    These folks performed a colonoscopy/endoscopy on me a few years back. All good. So, I recommend if…read moreyou are over 50, without any family history or symptoms, get a colonoscopy! These folks will fix you up.

    The two stars is only because the staff was perfectly lovely…read more BUT if you are a woman with any neurodivergencies, DO NOT SEE Dr. Huang. My experience with Dr Huang genuinely haunts me, as one of the worst experiences I've ever had in any medical context. It has been a while, but I was encouraged to come say my piece better late than never. I went to him with a series of issues and symptoms, well documented for many many months. At the time I was throwing up 3-5 times a day against my will, partnered with awful abdominal pain and chronic fatigue. We had a virtual appointment, and he was listening to my symptoms as normal. but once he saw my medication list and saw I have a mental health diagnosis- he immediately went totally cold and dismissive. Like I was wasting his time. I literally can see his face now. I was emotional trying to explain the struggle of what I was experiencing. But he said that in his "expert opinion" there was NOTHING wrong with me, and my mental health was the cause of me THINKING something was wrong.... i was so confused an devastated, i just asked "you're not even gonna check if something is wrong?" And that's when he said one of the worst things he could say- "I could do an upper endoscopy if you WANT.... But I'm 99.99% sure I won't find anything wrong" Well, i never saw him again, I was utterly devastated with my treatment, after waiting months to see him. BUTTT guess what? I did get that upper endoscopy at another practice- Turns out I had 1. CHRONIC GASTRITIS, 2. BARRETS ESOPHAGUS, and 3. multiple vitamin deficiencies found through blood work (that he didn't bother to do) Essentially- he couldn't have been more wrong. But he delayed me getting adequate care by making me have to fight to even be seen as a Person beyond medications on a chart. I'll never forget the way his face changed, the way the care left his voice as he just assumed maybe some people have had good experiences with Dr Huang, but the way he spoke to me and the things he said still haunt me- an example of some of the worst of what women and neurodivergent people face just in seeking diagnoses. If these things apply to you, and you've been struggling to find/waiting to get in with a good doctor who actually cares to help you.... Do not risk it with Dr Huang.

    After three bouts with bleeding diverticulosis, my Internist referred me to…read more Dr. Yoo. I had to wait a bit for his schedule to free up to see me. He's that popular. After the successful surgery, Dr. Yoo was so comforting to talk to and reassuring. He explained everything about the surgery and how well it went. The post op appointments were more than I expected because he wanted to make sure that I was healing well on schedule. I highly recommend Dr. Yoo. I will miss our post op conversations. Dr. Yoo is the best!

    If I were to write a review for Dr. Yoo it would be a five star review. As a Dr. he is stellar…read more As far as the medical practice, I was disturbed by what I was told, not only did I have to pay my copay but I was going to have to pay for the appointment upfront. I don't have a deductable and they insisted that I had to pay that upfront. I understand the reason why. The next time I walked in, I was immediately told my co-pay when I asked about the the credit I have on the account, the girl looked at me really confused, she acted like she had no idea what I was talking about while the girl next to her was telling another patient about having to pay for an appointment as well as the co-pay. I presented my insurance statement showing that it was paid (a few weeks ago) and she walked away somewhat confused. She said she wouldn't charge "This Co-pay" and I couldn't get a clear answer as to when I would be seein a credit on my credit card.

    Dr Patel is a gastroenterologist whom I visited for a colonoscopy. She is very professional but…read morealso reassuring about the procedure, which I had previously had unpleasant experiences with elsewhere. The procedure was done under general anesthesia, so I slept through the whole thing and felt nothing. I awoke quickly afterward and did not experience any discomfort at all. My whole experience there was pain-free! Dr Patel explained the results (which were good), answered my questions, and gave me a written summary and also a photo taken from the endoscope showing the general condition of my colon. Afterwards Dr Patel went beyond the call of duty and very graciously gave me a ride home in her own car when I couldn't reach my friend who had dropped me off and was supposed to pick me back up later (they don't allow you to drive yourself). We found out later there was a glitch in his cell phone coverage so his phone didn't even ring, but in the meantime I had no money for a taxi and the surgery was closing. I offered to take the bus home but Dr Patel didn't think that would be safe, even though I really didn't feel groggy from the anesthetic. I am very grateful to Dr Patel for her kindness in going out of her way to drop me safely back home!

    Pre colonoscopy appointment with PA went fine. From there it goes downhill. NO RX for prep pills…read morecalled into CVS. CVS says call United Medical Group to get prescription (which I assumed they would handle since I had a pre op exam). Calling now FIFTEEN TIMES and like others have mentioned NO one answers the phone. Seriously since United Medical Group take over of this practice - it seems to have gone down hill. Guess if I can't contact them - time to get ahold of some medical agency that oversees this practice.
