Hi Shonda,
I'm not sure about how to find a good doc for chelation. But for adrenal/ thyroid you could check this aptly named page on "how to find a good doc" from the stop the thyroid madness website:

http://www.stopthethyroidmadness.com/how-to-find-a-good-doc/

There is a link on that page to patient recommended physians that deal with thyroid/ adrenals. As they point out any doctor can get on the list just because they were nice or the patient like them for some other reason so you still have to be carefull. However, that is how i found a good doc here even though I didn't end up following her recommendations lol.

There are some other suggestions there on how to find a good thyroid doc.

cheers,
Cara
