The biggest surprise was my son--he used to be afraid of the dentist, but not anymore thanks to Dr. Audrey. Now she takes care of my whole family. They're also very honest. I paid out of pocket for my son's cleaning, and they later helped check insurance, got it covered, and even credited me back.

For the first time in my life, I am not dreading going to the dentist. Thank you, Dr. Rodrick!

I should have listened to the online reviews about Dental Group of Covina. My experience was marked…read moreby poor communication, scheduling failures, and a lack of attention to important patient care details. My oral surgery consultation was scheduled for 7:30 a.m. on May 20, 2026. I arrived at 7:00 a.m. and found the office closed. An employee did not arrive until 7:23 a.m. and informed me and another waiting patient that the doctors would not arrive until 8:00 a.m. We were told someone was supposed to call and reschedule us, but neither of us received any notification. I later overheard staff discussing how patients had not actually been rescheduled as claimed. The dental assistant and Dr. Kevin Dorsey were both professional, knowledgeable, and thorough. After my consultation, I was given a cost estimate and a referral for a CT scan. I was verbally instructed to fast before the procedure and complete the CT scan. No other instructions were provided. The day before my June 3 procedure, I received a voicemail stating my appointment was canceled because insurance authorization had not been completed. After being on hold for 26 minutes and disconnected, I eventually spoke with the office manager, who suggested I pay out of pocket. When I contacted my insurance company, they informed me that Dental Group of Covina had never submitted the authorization request. My appointment was canceled due to the office's failure to do its job. After filing a complaint, my appointment was reinstated. However, when I arrived on June 3rd, I was told they could not process my CareCredit account and suggested rescheduling again. Then I was asked whether I had stopped taking my medication before sedation. This was the first time anyone mentioned that I needed to discontinue medication a week before surgery. I was never verbally informed, nor was I given written pre-operative instructions. At that point, I decided not to proceed. Too many critical details had been overlooked, and I no longer felt confident in the office's ability to safely manage my care. This experience cost me significant time, multiple trips, countless phone calls, and two weeks of lost pay. Patients deserve better communication, organization, and professionalism than what I experienced at Dental Group of Covina.
