It is good to check the qualifications of any health professional, especially doctors, psychiatrists. therapists....
Even if a jw were well qualified medically, we know that your right to confidentiality would be preceded by "loyalty" to the elders. That would be the same situation were we hiring a lawyer. Your confidential would be at great risk. The wrong assumption many ignorant jws make is that the elder system is one based on confidentiality. We have seen too the the WTS written policy is that jws in the health profession must reveal things to the elders and be willing to suffer the legal consequences.
Even as a jw, I never hired a jw for anything, loaned them money.
Every elder body has one elder who can't keep his mouth shut, telling either his wife or an elder from the nearby congregation (who then tells his wife).
