I would ask him. If your issues are not an area he specializes in, he may be more comfortable referring you to someone who is more competent in that area.

I remember I "checked out" a new therapist many years ago. We had one session and he determined he was not the right fit for me and let me know right way. It saved me investing time and money into something that wasn't going to work out any. It's in your best interests to have a T who is experienced and skilled in working with your specific issues.
