Patient Comments (4)
Covina, CA |
I agree with the previous comments regarding the long wait-time and the staff. I will add that sitting in the waiting room is a dehumanizing and cattle-like experience. Seeing Dr. Merla did not make up for the wait. She did not add anything of value, and she did not seem to be motivated to help determine why my son is so ill. I found this to be very frustrating because she seems to have the intellectual potential to solve the medical mystery; however, the empathy and motivation are lacking.
I wish I would've done research! 1 1/2 hrs late for procedure, got so much wrong, best was reporting a med I've taken for 2 mths caused a 5 yr problem! I get a GI every 2-3 yrs & I wish I did research because now I have to do this all over. 1st visit was 3 min w/ her NP which was spent scheduling procedure - saw Dr for LITERALLY 1 min before GIs and then they tried to schedule me w/ NP again. Someone reviewed she was a "one trick pony" - they're not far off. If you need a real Dr save yourself!

Her office seems backed up every time I go. They have a patient overload. The wait time is always at least an hour. As for Dr. Merla herself, she seems thoughtful and smart, but stretched out too thin. It is difficult to get appointments with her. She also never notified me when she received my test results and by the time I called to hear about them, I couldn't get an appointment to discuss them with her for another month. I think they're just overworked and understaffed.

My husband had an appointment at 2:30. I was told to go at 2:00 to complete forms, we did. We were not given forms, after 30 minutes I asked for the forms. They gave us forms and asked for his insurance and ID. She called me up, I gave her completed forms and ID. She asked me to come in the back, she tells me the appointment was cancelled, and we needed to reschedule. I never cancelled. We arrived at 2 and left at 3:30 without seeing the doctor. Very rude office staff, no apology given.
