OK, in addition to all the Worthies that have been noted, I'll add a few from memory (I'm sure there are more but they will have to drift up from deep memory or I'll have to dig thru my bookmarks!)
John Kari
Dale Saso
Mike Celmins
Greg Diamond
John Sencak (Wolf Cycles)
Sam Cotton
David Ybarrola (Persechini)
Jeff Lyon (migrated to Oregon)
Joe Breeze
John Murphy (Columbine)
and if you stretch the concept a little, since he apprenticed with Eisentraut so did at least his early work in Cali:
Mark Nobilette
and if you really stretch and include Reno as an honorary California suburb :
Roland Della Santa
whoops, just thought of a couple more:
Chris Kelly (in Oakland, or was it Nevada City?)
The Sycip Bros. (Sonoma County)
Steve Rex (of course!)
Scot Nicol
John Castellano
Ross Shafer
Rick Hunter
