Very unusual that a JW is a Psychiatrist.
I grew up in New England and knew of only one. He was somewhat of an expert in depression. And was also Presiding Overseer (older term for COBE) of his congreation while treating various brothers and sisters.
This Eleder became somewhat of a stat in the local area. BOEs all over the circuit and beyond would consult with him regarding members who were depressed or abuse survivors.
I sort of wonder if the above story is about the same person ? Its possible.
