I have absolutely no issue with Dr Daya. He is thorough, very friendly, and explains health issues well. I DO HAVE AN ISSUE however with his RECEPTIONIST and OFFICE MANAGER. I manage my 89y.o. mother's health care as she is frail and has mild dementia. She had an appointment May 12th (I believe) to get an EKG, but we found out after we arrived that the appointment had been cancelled 1-1/2 hours prior that morning with an attempted phone call that went into VM. So while there we scheduled a replacement appointment for May 19th. Then when we arrived on that day, we were informed that the Technician failed to show up and this time they failed to call. Strike two. Then in setting up another appointment, the Receptionist at first scheduled it for May 31st. I asked her if she was certain she wanted to set it out into the second week instead of the next coming week? At first she seemed confused and then said, "Oh no! Let's set it for May 24th and I will do whatever it takes to work you in at 10:30." And before leaving, I confirmed with her for the 24th and she agreed. When we arrived on the 24th there were at this time two receptionists at the front desk and the one that we had scheduled with seemed confused. They both went into the back area and when they came back out, the second receptionist said we did not have an appointment scheduled for the 24th, but if we wanted to come back in an hour they would "try to work her in" while the original receptionist remained silent. I did mention that my mother is frail and making these appointments is a task for her, so she told me she just wanted to go back home and never wants to come back to this office again ever. Later that day, I called USMD to complain about how we were received at the front desk denying our appointment as if this was our fault for coming on the wrong day. I told them that I did not want to lose a good doctor, but I need an apology from the office staff. Today July 12th, I received a call from Dr Daya's Office Manager asking me to set up a new appointment. I told her that I would like to schedule an appointment, but I am waiting on an apology for how we were treated making three failed appointment attempts only to be turned away each time through no fault of ours. She informed me that she will not ask her staff to apologize and will continue to defend their actions. She said she will have her district manager to call me with an apology. We shall see.
