Orange County Ca: Good Affordable Vet for my Dog?

I just moved back to Orange County and when living here before I never had to take my dog to an actual vet due to being healthy and getting his vaccines at Discount Animal Clinic. He's gotten a little older and I think we are dealing with arthritis or hip dysplasia so I'm trying to find a vet I can trust but also one that's affordable. Any suggestions? I live in Santa Ana/Orange area.
