I haven't worked with Michael McEvoy myself, but I'm friends with him on Facebook and always feel like he is very knowledgable and I like the way he answers my questions. I know that he does phone consults, and uses hair mineral analysis from ARL and does blood work analysis.
He is definitely up to snuff on AF as he is always talking about it on Facebook. Armstrong on here just met with him recently, so you might want to talk to her and see what she thinks so far.
