I would have rated a zero...Like many have said, making and getting an appointment is ridiculous! One and only one person is able to make and take appointments for all 4 locations? You have to leave a message each and every time...and WAIT.
I had made an appointment for my hard of hearing 76 yr old dad in June. I wish I was there to help him but I live in a different state. (He drove by the Smoke Ranch location the day before just so he knew where it was and not be late). The morning of the appt. he arrived early as instructed only to be told he DID NOT have an appointment. The 3 front desk personnel were RUDE, unprofessional and they made my dad feel disrespected as they giggled and carried on. No one attempted to show they cared.
I contacted and maneuvered my way into their phone prompts and extension and managed to talk to the very front desk person. According to her she claims that the office had tried to contact my dad (and sent a letter!) stating that his appt. needed to be rescheduled. My dad received no such communication. The way this office works tells me they could care less about you and being a patient.
