I am not MissBoots, Sunrise, and I hope you don't mind if I share how I found out about my last T, I just asked her. I told her I was a Christian and I would want my therapy to be biblically compatible and then asked her; she said she was not a believer

but we worked with that (or I did).
The new one I have now is Jewish which is fine I think she does practice her faith. For me it was an important question to have answered at first visit.
