What code of ethics? (As though hers is the only one.) I'd ask her point-blank to (a) produce you a complete written copy of the code, and (b) name its source. Is it something from the American Psychological Association? A professional association or other governing body for her particular method of therapy? Or just something she wrote up? If the latter, can she show you the whole code, or is she just alluding to one but can't produce its documentation (a bad sign indeed)?

You can't properly judge whether she's honoring or breaching her "ethics" till you can see for yourself exactly what they are. And if she claims it's from some organization, be sure to search it on your own to see if it really exists and appears reputable or shady. Also find out what "teeth" the code has and what recourse (if any) it offers you in the event it's breached.

As for the ethics mandated by the laws of your state, I'd find out what agency handles licensing of therapists and check her for disciplinary actions there. Even this can be tricky -- at one time in New York State (this may or may not still be true), a "psychologist" had to have certain advanced degrees and credentials, but anyone could hang up a shingle as a "psychotherapist."

You might also check your local general-jurisdiction court for malpractice suits against her. Look for documents called the "complaint" (why the suit is being brought) and the "answer" (the defendant's rebuttal to the complaint) as well as the documents indicating how the case was disposed (was a monetary judgment rendered, did the case go to mediation, was it dismissed after a settlement?). This is how my wife and I dodged several bullets from careless surgeons she almost let operate on her, and you don't have to be a lawyer to do this, as court papers are public records.

In either case, don't just rely on HealthGrades -- they only keep data on disciplinary actions for five years back.

Here's hoping her "ethics" are actually meaningful and have genuine positive value. The point of any worthwhile ethics code is to provide transparency, not a hiding place.
