Small/cheap schools in Newport Beach or Irvine?

What is this kbs you guys are referring to?

I think Nam Pham used to teach classes every now and then out of some place in Costa Mesa no? That was a year ago though, don't know if he's still doing it, he's a badass though and super-nice, so i'd definitely recommend him if that's going on.
