I have my T's email and work cell but I've never called her phone. I only email for scheduling purposes, mainly because I don't want to email her something important and be disappointed with a short response.

My T is a part of a clinic but there are no receptionists, all the therapists do their own scheduling and communicating with clients so that's one reason she has to give me her email. I think it is on their website anyway so none of them try to hide it.
