Where can I find a list of the top CPA's in the San Fransisco area?

As a CPA, that is a subjective question.  I would start with the San
Franisco chapter and drill down from there.  The question depends on
what you are looking for: audit, tax, valuation services, etc.  What
industry are you in?  Energy, real estate, medical, etc.  In other
words, the best real estate CPA is not the best tax guy.

Here is the chapter's link.  I do know this.  The best CPA for you
will be a member of the chapter.
