American Association for Marriage and
Family Therapy
This site has AAMFT resources. I'm not familiar with AAMFT, but my
initial impression is good. My thanks to Andrew for making me aware of
the existence of this organization.
Therapist Directory
An online professional referral service, but so far only covers North America.
Started in 1995, the site has been accessed over 2 million times. You can ask for
information about joining the
directory here.
The Therapy Network
From their main page: "The Therapy Network was
created to bring therapists and clients together. Finding a therapist when you need one
can be a difficult task...if you don't know someone who can recommend a therapist to you,
it's often hard to know where to start looking." You can list your service at this link (you'll
need a web address).
