I didn’t interview, what happened for me is originally he was hired by me to work with my nonverbal autistic daughter, so by chance because i sat in on her appointments I got to see how he worked with her. After about a year I asked him about his history of specific aspects of trauma and he was familiar, had experience. He cautioned though that we had to end her therapy and by then she was good so was discharged and I signed on. I’ve been with him for a very long time. If i had to interview I’d ask about my particular trauma, what the options were that he worked best in. given he has a huge background, he uses a go with the flow approach where it is client led, but also no plan it is whatever shows up in the appointment. As we progressed I’ve asked for things and they were readily given. That was particular to my type of trauma, given I was told how to be, how to live, what to do, what was acceptable, so his approach to not put demands on me to let me learn to ask for help, understand choice, understand what it means to ask for help and be given it no questions asked, to take the lead in my life, well its been slow but wonderful method for me.
