I have no idea if the first one I see has a supervisor. She is married to another therapist (second marriage/he is older than she is) so maybe she uses him as one. I imagine she does not think she needs one at this point. She mentions every so often that she has 30 years of experience (big whoop is my usual response).
The second mentioned she had someone she talks with at times.
I have never really cared if they had supervision or not. I more care that they have endured therapy themselves rather than having some quasi-super thing where they only tell their side of things.
