Clay Shooting Classes in LA?

I've been clay shooting a couple times with friends but haven't bought my own shotgun or anything. Just got a membership @ Oak Tree to shoot my pistol and saw they do a weekly trap league. Sounds fun, but are there any recs for lessons in the LA area? Every time I've gone in the past it's just been shoot until you run out so I don't know how the actual sport works haha. Plus I know the setup is different for a clay shotgun vs like a home defense one but not sure what I should be looking for.
