Being called "Dr." and having her license revoked are two separate things. The doctorate is an educational achievement that really can't be taken away although a school MIGHT be able to revoke it in extreme circumstance, but really doubtful. She can be a doctor of psychology while not having licensure. Licensure is something that many professions have to go through, just like a contractor's license or a teaching license. You have to pay some fees, pass a test, and undergo a couple yrs of supervision to become fully licensed as a therapist. If you screw up, they very much can and will yank that out from under you.
If I were to guess, based on her writing ability and seriously odd beliefs about her reptiles, she probably was a therapist and got her "doctorate" from some bs new age school if she has one at all.
