I felt it was important for the T to have a website or profile online...was just something I wanted as it was super scary to think about going to see someone who was just a name - with no idea anything about them or what they looked like....This was just a personal issue as I was EXTREMELY anxious. I also needed to be able to email them first.
I wanted to find a T who was more humanistic/person-centered with understanding of trauma rather than CBT....I also knew I preferred a male T and one that wasn't too much older than I am...
I needed someone who was really kind, gentle etc but who could also challenge me /: I know that's prob asking a lot, but the T I found seems to be a good fit in this way. He was really accommodating and helpful from the very first email I received back from him. He's always willing to help me when I feel un-helpable. But he doesn't let me get away with much - he's always calling me on my crap

lol
I would just email around or call, if you feel comfortable doing so, and ask some basic questions. Even just if they take your insurance. I could get a feel from the way the Ts responded as to whether or not I wanted to pursue it further. It really helped that my T offers a free consultation session to see if we wanted to work together
