Ask away. Information about professional licenses is public.

I had a T who did this very thing. He was arrested, lost his license.
I was devastated because he just disappeared with no warning and it was several months before I just happened to hear why he left suddenly. The community mental health center wasn't saying.

It just so happened that the T that I saw after that, a T I returned to for a while, knew of my T who disappeared. He asked me how I felt about that T and I told him that I felt really bad for his family because they seemed like a close family (from photos he displayed and vacation stories he shared) and that this must have been so hard on all of them. After I told this current T how I felt, he then shared with me that the former T was in therapy and in a program at the hospital that the current T was running for situations just like this: the program was to assess the person to see if it was realistic for them to stay in the profession in any form.
So, I came away with a bigger picture than what I had initially. Former T had made a serious mistake that affected many people and his profession that dedicated so many years of education to. Like all our mistakes, I hope that he and all those involved were able to heal and work through this.
