What else would you like to say about your experience?
My appointment time was at 11 a.m. I did not see my doctor until 12:45. The wait time is horrendous. That needs to be improved. They want you to get there 15 minutes early before your appointment so you can sit there and wait for two hours. Thank goodness I didn't have another appointment right after this one. Improve wait times.
