The front desk receptionist is very rude and unfriendly to patients. They do not accept Covered California patients.

BEWARE! This office is very UNPROFESSIONAL and Dr. Christi Cheng is emotionally unstable and rude…read more When you call to make an appointment the guy that answers the phone works from home because there are children in the background yelling - he has you on speaker phone so you can barely hear him. I was taking my son in for a follow-up post ER visit after having several focal seizures and was going to request a referral for a new neurologist. Long story short, Dr. Cheng became UNHINGED when she looked at her computer schedule. The appointment was noted on a different day, but when I told her the scheduler gave me this date and time she began yelling at us that she needed to see the new patient first and we would have to wait (mind you, we're already seated IN her office). When I told her that we had another appointment and that we couldn't wait, oh, she really got confrontational! I told her it was very unprofessional of her to react that way in front of my son who wasn't feeling the best. I had to calm him down in order to avoid causing another seizure. We left the office without the care he needed and felt very shocked, disheartened, and discriminated against.

Like many other reviewers here, we had no idea where to start and so we used Yelp to help us choose…read morea civil surgeon for the I-693 form in Oct 2025. David answered the phone quickly, and it was clear that he was a very compassionate person and I felt very strongly that we would be in good hands at this clinic. Both David and Dr. Perez worked to get us the required vaccinations for the lowest possible cost, even though that meant that they didn't make any money by giving her the vaccines themselves. They clearly want to help people through the residency application process and their kindness and compassion is both remarkable and very much appreciated! Thanks to their assistance in getting all of the medical records filled out, my wife was granted residency in April 2026 and we couldn't be happier :) In summary, I'm very happy with the services provided by these two wonderful people, and I give my highest recommendation to Avanzado Medical Group for anyone looking for a civil surgeon or is in need of other medical care.

The I693 I previously completed had expired so I needed to have it redone…read more I sent a text to the number that was previously used and in the morning got a call back from David. His voice/tone: direct. The call was super quick but truly informative that highlights David's systematic approach. I asked for the soonest available appointment and confirmed. I then received a text from him with the address and documents I need to bring. On the day of the appointment, we thought I'll be late so I called the office but ended up being early even. Considering that I said I'll be late, I assume David wanted to be productive during the time that I said I won't be there yet, so he started another task. Truly understandable. He still accommodated me and dropped that task he was doing. I really commend this Medical Office as they are pragmatic and warm. And also, they offer the best rates compared to all the offices I called when I had the first medical. I am so thankful I found the Avanzado Medical Group! Thanks again David and Dr. Peter!
