There is no straightforward, simple formula for identifying the “right” therapist because the right therapist may be right for you but not for someone else.
Decades of research on the psychotherapy process show the quality of the therapist-patient relationship to be most strongly associated with progress in treatment.
So consider first whether you would prefer to work with a male or female therapist. Then schedule a few consultation appointments with different therapists and work with the one who feels “right” to you and who has the qualifications to treat your condition.
