I unfortunately speak from experience in this matter, lots of experience.
There is no sure fire good way to find a therapist. I have found them from a general referral, thru a healthcare listing, and by looking 'em up in a book. None is guaranteed to provide you a good therapist, or more importantly, a good match!
The thing to remember is, that this is not a marriage, it is not forever. You can leave their services anytime you want, so don't get to feeling trapped. They are working for you, to help you, do what you want to do. They are not in charge, you are.
If after utilizing their services for a short time, you feel it is leading nowhere, than tell them so, and tell them why. They will either adapt to help you or not. In the latter scenario, don't feel badly about dropping them. You are their client, not their slave.
I know sometimes you may feel like if you switch a therapist that you have wasted valuable time and money. True. But, how much more are you willing to waste staying with someone that is not aiding you to do what you want to do, to go where you need to go?
1.) Do not be afraid to interview them.
2.) Do not be afraid to tell them what you really want.
3.) Do not be afraid to fire them if need be.
Good luck!!!
