Right, don't over-think this.

A good therapist will be flexible in approach. Even they have a preferred orientation, they'll have a huge toolbox, and they'll find or design something that works for each client. Flexibility and creativity trump theory.

So maybe pay more attention to the emotional match? Are you comfortable with this T; can you be honest with him? Are you two a good fit?

If you two are a good fit, then you will be able to discuss and work through any therapy process issues, and that includes him being Jungian and you not.

(And besides, logotherapy and Jungian approaches might make for an interesting juxtaposition -- I can see them as sort of complementary. I mean, it's not like you want CBT and he does psychoanalysis!)
