My T keeps a pretty regular schedule and I haven't (yet) had any issues with getting/keeping appointments. Same for my pdoc. Even it restricting to late afternoon/evening appointments, I have no problem getting in within 2 weeks and she is only there 2-3 days a week.

I had a doc many years ago that was very hard to see. Make an appt 3-4 weeks out, then the week before they call to cancel and reschedule as he was going to be out of office. Another 3-4 weeks out. Could take 2-3 months to get in. After 2 visits I left. Why deal with that?
