I’ve worked in the medical field for 40 plus years and have been acquainted with many psychiatrists, psychologists and assorted therapists. I knew one that was a sexual predator of children. His specialty was treating children. Two others I knew were just plain sexual predators.
I also knew maybe a dozen (over many years) that were kind, insightful and gifted. They had a knack for healing. They inspired patients to face their demons and get better. They were the exception in my experience. I observed power-driven, bitter doctors who were spiritually exhausted, and some who were far, far sicker than their patients.

I’m interested in why you asked the question.
Sort of an analogy about attorneys. Ninty-nine point nine of them make all of them look bad!
