On this site, on the very first page, there is a forum called "good MB shops". You can search this forum. Put "San Diego" as the search term and see what comes up.

If you don't get anything, you can post the question on that forum and someone in the area may give you a lead.


Edited:

Here, I did it for you. Many good results:
