Functional doc in Michigan familiar with a--fib

I see a functional med doc here in MI. I know Dr. Joel Kahn is here as well (he was within walking distance!) --- i have a friend that sees him and has afib and i'm just not sure he really does "get" it. She seems to do a lot of her own research on the topic. He is like $1000 which is OK if he is good. Does anyone here see him? Feel free to write offline. Or know of another functional doc in the area. I was just reading a long recent thread on Mg and i can dive in and figure out what needs to get done (I"ve done it w/ other things) but i kinda want some hand holding...
