This office put me through the ringer of stress and BS when I called requesting helping from a physician who I presumed knew enough about UC to know that jury duty is an unequivocal nonstarter.

There are others' who calls themselves doctors and NP out there, who can take a page from their books to improve themselves as human beings and who they claim to be in their profession.

I initially scheduled an appointment to establish a primary care physician with Dr. Snyder. At my…read moreappointment, this was not that. And this was no fault to Dr. Snyder at all. I came in and Johana checked me in. I was missing some questions on forms and that got squared away along with my insurance card. Quick vitals check and then Dr. Snyder and his scribe came in shortly. I indicated I was looking for a primary care physician. He thoroughly explained he is not that and more of a specialist. We figured out it was still the appropriate venue to schedule a procedure. He then recommended a primary care physician. All in all, professional from the moment I walked in, checking in and meeting with Dr. Snyder.

I recently went to see Dr. Yoo for a colonoscopy. I found him through my insurance company website…read moreand saw that he was located nearby in Rowland Heights. When I called to make my appointment, I found out that Dr. Yoo moved his practice to a new building in Diamond Bar as of March 2024. Dr. Yoo's new office is located in the newly renovated Diamond Bar Medical Plaza, which was previously a Chuck E. Cheese (if you all were in the area when that was around). Looks like they are still in construction, as a couple offices are still vacant with plastic on the glass windows. The staff I encountered all very friendly and nice. Dr. Yoo was professional and clearly explained the process and indicated what I needed to do to prep for my procedure. I came in on a Monday and the front staff was able to fit me into an appointment on Thursday due to a last minute cancellation. This kind of procedure is not fun, but the entire staff made me feel comfortable the entire time, and the nurse who attended to me was so nice, I felt like my mom was taking care of me. =) She made sure I had extra blankets because I was cold and came by a couple times to made sure my IV was ok. I got a call the day after to follow up and see how I was feeling and if I was experiencing any issues. I appreciate the check in even though I was feeling good! I highly recommend Dr. Yoo if you need an gastroenterologist.

On one occasion, I received multiple phone calls in the same day asking why I had scheduled an appointment before my ultrasound was completed. I repeatedly explained that the appointment was to discuss the results of a previous ultrasound, which had already been completed and was in my chart. Despite explaining this several times, they continued to question me. The final issue that led me to cancel my care was when I was scheduled for an endoscopy. No one contacted me beforehand to explain what my out-of-pocket cost would be. Since my procedure was the next day, I called the office because I didn't want to be surprised by a large bill. I spoke with Maggie, and the interaction was extremely disappointing. Rather than listening to my concerns, she repeatedly talked over me while I was simply trying to understand why the office couldn't provide an estimate after obtaining the insurance authorization. It felt like the office was focused on getting paid by the insurance company but not on making sure patients understood their financial responsibility ahead of time. Instead of helping, Maggie told me to call my insurance company or the surgery center myself. I explained that I didn't understand why I had to make multiple phone calls when the procedure had been scheduled through their office. Even after I politely asked her to let me finish speaking, she continued interrupting me and eventually hung up on me. I have worked in customer service for many years, and throughout the conversation I remained respectful. There was nothing that justified ending the call that way. As a result of this experience, I canceled my procedure and will be finding another gastroenterologist. The physician may be excellent, but the office staff's communication, professionalism, and customer service need significant improvement. Based on my experience, I cannot recommend this practice.
