This is a really important recommendation, WTR. Therapists will list technique after technique in their Psychology Today and website bios, stating they offer a variety of different therapy approaches. Many techniques/therapies have very specific certifications requirements (ex. DBT, EFT, EMDR, Transference Focused Therapy, Mentalization Therapy etc.). Some therapists will go to one or two "general" CE workshops on a technique, which is actually just a day or two lecture on how the technique works or the basic tenets of how it addresses a certain mental health issue, and then the therapist lists themselves as "using" that therapy method in their own practice. Not kosher in my opinion, and one of the reasons a client needs to really check a therapist out. This practice is one of the reasons I say that there is a lack of "oversight" in psychotherapy.
