RebE, thanks for the text. It looks like Rav Moshe would approve of Jewish psychologists!
YM, I think you can read this that expertise matters, which is a usual attitude in medical matters: shomer Torah is preferred, but if the only one available mumhe … I imagine if Rav Moshe would advocate going to a non-expert may be an option, he would say that.
And both of you, could you do me a favor. As Syag noticed, I don’t like loaded terms like “frum” that everyone interprets as he wants, usually to exclusion of others. Rav Moshe says simply “shomer Torah”.
