Psychology Today. It shows endorsements from colleagues. Of course it can be great to get someone who is recommended by a friend, but Psychology Today verifies the therapists they list and you can see which have been endorsed by their peers.
I have not had any problems finding therapists that take our insurance (Blue Cross Blue Shield). Each of my daughter’s sessions is a $25 co-pay. Would be $150 w/o insurance. She can go to 6 sessions under insurance for what it would cost for one session w/o. If you have plenty of money to burn feel free to pay out of pocket, but I would rather save that money and get more sessions in with a good LCSW who takes our insurance.
