It should be the Fairfield affiliate.
That's what I would have thought but the CF Fairfield County site says that he trains out of a different gym in Westport.
As for "no grunting" -- I don't know. I have some clients who belong to PF just because it's so cheap they consider it a no-brainer -- that way they can do CF with me and then hit PF on days that they don't come to me. (And if $10/month buys use of a treadmill when the snow is flying, I can see the logic of that argument.)
