I did a lot of prior research on the therapists that I saw for initial consultations. Looked up lots of stuff that was available on them and their work online. Then "interviewed" a few before I chose one based on a mixture of their education, experience, approach, and my own first impressions. Maybe try something similar? It would limit you to therapists that do publish online info, but at least you have information to start with. Then I would ask them in the first session about how they work, how they like to run the sessions, what sort of feedback they like to give. I am seeing someone who was originally trained as a social worker but he has extensive training and experience with psychoanalysis and clearly has his own unique style to it that was already apparent from the online info. For a while, I felt that he was not giving me enough feedback, but then I discussed these feelings with him and asked if we could do more. I think it's hard to criticize the therapist, but if we never express our preferences and concerns it's unlikely the work will satisfy our needs unless it just happens to be a very fortunate click, which is rare in any relationship especially in the long run. Also, my opinion is that rather than initial training, it probably matters more how and how much the therapists continue to educate themselves and work on themselves. School is a start, an important one, but what means much more, I think, is their independent work and openness.
