log..
I can't help you since I'm not a PT or anything.. but
I believe ACE seems to be pretty prevalent here in CA anyway. That's what all the ones down here seem to have certs in?.. with?
However, if I were you, I either join a PT group/club/org and gather more info about each of the certs and/or I'd call a few clubs and some self employed PTs and ask them about certs.
Or you can look thru the phone book.. do they have these anymore?, and look thru the PT section. I'm pretty cure if I had any cert I'd advertise it to differentiate myself.
Push the pedal down watch the world around fly by us
