Is ussd a mcdojo? In my opinion yes. They came from fred villari www.villarisonline.com
in 1988 mattara left villaris and opened about 30 or so schools in cali.
Their art is really mixed, it has kempo in it but I've never heard of any shaolin in it. I have heard that there is some shotakan forums in it.
I think its a mcdojo because mattera changed the kempo combs name to shaolin defensive maneuvers and on his web site and his manual he makes no mention of grand master fred villari, who he reveived white thruogh 7th degree black belt.
And you cant own a dojo with them 100% any more. And it cost around $120,000. Run away!!
