Dr. David Clark?

Came across a slew of interesting videos on Youtube by him. This one connects Hashimoto's to mercury. I have high TgAb but normal TPO, so it was of interest to me. https://www.youtube.com/watch?v=Evtn27OxLoY

I then got his "thyroid report" which is long and filled with both great information and not so great typographical errors: http://trianglethyroiddoctor.com/low-thyroid-report.html

And I wondered about his clinic. http://trianglethyroiddoctor.com/

Anyone have any reviews of it?
