To be honest she sounds reckless. She doesn't have the clinical experience to start inventing her own "unique approach" and what she shared on the phone is mind-boggling.
Here on PC we take care to add a trigger warning for that kind of thing, yet she'll happily blurt it out on the phone to a potential client she's never even met?! She sounds over-confident and has the potential to cause damage.
Sorry if I'm coming across as overly harsh, but I have been damaged by over-disclosure, and I wish some Ts would think about the impact on the client before they open their mouths.
