I used a personal referral that I then researched before making an appointment. Interestingly, when I've looked on Psych Today for my area, the only Ts listed there are either fairly new to practice or the area, have minimal credentials, or are Ts I know of from living here for many years not to have great reputations. It may be different in a large city, but in a smaller area, I think the best Ts are fully booked through word of mouth and referrals from other community resources.
