60 mins, +/- 5-10 minutes once per week. Sometimes we start on time and go over; other times we start late and finish on time. T never abruptly ends a session but always ensures I am grounded before leaving, so it doesn't bother me that sometimes our sessions are shorter. Whenever they are it feels okay for them to be so at the time.

Payment and scheduling don't need to be done in session time (both are automatic) and we generally don't have out of session contact (I have sent her two emails in 18 months).
