The only person I'm aware of in the northeast who teaches using PMTS methods is Glen Scannell, and he's based out of Waterville Valley, NH. If VT's your thing though, we're having the northeast meetup there in February, and we'd love to have you. Glen will be there, and I suspect that once you ski with him, the drive to Waterville might not seem quite so far.
There's more info in the thread in the Posse section:
