I recently moved to the area and needed a new PCP. I spoke to a colleague and he uses Dr. Z for his kids for the past 5 years. Skeptical I went to see how he was. I got there early to do paperwork and was taken in before my appointment time. The staff was friendly and very helpful. The doctor was friendly as well. I had no issues in and out in no time without any issues. I was very pleased going there and will be back in the future.

Dr. Zamora has been my doctor for the past 20+ years. He is a wonderful doctor with a lot of knowledge, if he is not available for an appointment Carla and Katrina are amazing as well. If you are looking for a PCP that will take care of you and is reliable this should be your new PCP office!

My review is based on today’s visit. I had a 2:45 Appt with PA Katrina Jackson. I got there early.
I was take. To the exam room At 240 to 2:45 pm
I have been using this clinic for several years and this is the first time I have a complaint. I was left sitting in the exam room for 45 minutes. And which time I decided to leave. I try to be very patient but 45 minutes is really uncalled for especially because no one came into the room at any time to tell me the PA was backed up in another room
No I realize things happen or a PA can get tied up with a patient, but she could have at least had one of her nurses come into my room and explain what was going on so I could make an informed decision whether or not to continue waiting or reschedule.
When I walked to the front window to get a refund on my copayment the receptionist was speaking to Katrina telling her I wanted a refund and I heard Katrina say OK no problem.. no I would’ve thought that she would come out and at least tell me what happened or apologized but she did not.
I’m sorry 45 mins is just unacceptable. Time for me to find a new doctor.
The front counter stated they voided my $25 co payment and the next day the amount was debuted from my bank.....
