I applied to see him in late Jan/ early Feb 2016. I've called around once a week and emailed 1-2 times a month to check on the status of the application. As of 9/2/16 my application finally went into his office for review. No word yet on whether he has accepted me.
So far it's been 10 months and no word on a possible appointment date, but I was expecting a wait. The hardest part is I have a progressive form of the illness and working makes me worse, but I want to hold onto my insurance because Peterson accepts it.
If I get in I will let you know

I'm near Sacramento CA, so I really hope I can see him since travel would not be as costly. I'm hoping he'll go for my low NK cell function of 8 LU.
If you apply to see him, I recommend making 2 copies of all your records just in case his office loses your application (didn't happen to me, but I've heard it has happened to others). That way you can send another without having to find all your tests again.
