Really great discussion here! To answer your initial question, my T does not specialize in PTSD. After we got knee-deep into stuff ( a few years in), he suggested I consider switching to someone trained in some other modalities. For multiple reasons, and with his blessing, I declined--I have a very good working relationship with him that has been hard-won, and I do think what he is doing with me is working.

I think it comes down to 1) do you feel confident in the T's ability to try to help you, and 2)does the T feel confident in her ability to try to help you.
