Hi B.,
I don't live in Keller, so I can't help you out with suggestions for other practitioners. I just want to say that I agree you need to switch practices! An hour and 45 minute wait is unacceptable. Seeing the PA, however, is acceptable. My doctor's office has also led me to believe that I had an appointment with the actual doctor, but instead, surprised me with the PA. It pissed me off at first, but then I got over it quickly when I realized that the PA is extremely capable of caring for me. It is much easier to get an appointment with the PA, too. However, if you still insist on seeing the actual doctor, you must specify that when you are making the appointment. Good luck!
