Any obdnce classes in San Fernando- Van Nuys- area?

[pac liter]

Was hoping to find a good obdnce class for my dog aggressive Lab.
Hoping to find something in the Socal SFV- Van Nuys (818) area

I need a class that teaches corrections so not very interested in pure positive training. Moderate trainers w/Schutzhund or protection background would ideal.

I already have a good trainer for my GSD, but he is very far.

Thanks everybody
