Well, I can't publicly speak to whether my organization or any other west-coast founded organization marches, etc. in their closed sessions.
But generally, I believe the west-coast founded orgs have the philosophy that the pledge education process is a private thing, and should not be viewed by the public.
In terms of the east-coast founded orgs that have emerged in CA, I know of chapters of the following:
Lambda Theta Phi
Lambda Theta Alpha
Omega Phi Beta
Sigma Iota Alpha
Lambda Upsilon Lambda
Lambda Theta Phi and Lambda Theta Alpha have a number of chapters throughout CA, but I only know of 1 chapter each of OPB, SIA, and LUL.
Edited to Add: Hey, that was my 1,000th post! Took me 11 years, LOL!
