Looking for a place to get Certified for Scuba Diving in southern California?

I want to get certified i live in corona Californa (near riverside) (south of L.A. north of san diego). I have been searching i have found about 1 place that im interested in. I don't want to be forced into going to this one place because i don't have any other options. So if you own a shop or went to a place you enjoyed let me know!
