Smaug, the evil psychiatrist, because she was a dragon.

The psychiatrists after her, both male, were Dr. Hot (I think?), Ethical Psychiatrist, who moved to another job, and Dr. Semi-Hot, Presumably Ethical Psychiatrist.

Dr. Biker Chick (DBC): insisted on being called Dr. [first name], very into motorcycles

Cactus Woman: pictures of cacti all over her website

Flower Pants: always wore flowered pants like the three times I saw her

Info: big typo on her paperwork, in a word all caps and bolded yet, INFORMATINO
