I've had therapists who are late but never more than 10 or 15 minutes, max. It can be hard to find a T who is a good fit. Mine is in private practice and was referred to me by my psychiatrist. I was overwhelmed by the thought of looking, so he had his practice director set an appountment up with my T. She's the only T I've had that I connected with so well and so quickly. So I think referrals by people who "get" you are a good way to find someone suitable, if that is an option for you.
