I attended an ABA school, but agree with Duncan's point for the most part an attorney is an attorney. There are some places that have elitism and anyone attending a CBA school should be realistic in their expectations as they are unlikely to clerk for the Supreme Court right out of law school, but there are plenty of people in need of legal representation and most clients simply want an attorney to resolve their problem with a law license from any school you can accomplish a goal for your client. I don't think anyone even CA Law Dean would encourage someone who wants to work for Cravath or O'Melveny & Meyers to attend Monterrey College of Law as those doors will be closed, but someone that wants to do Family Law, Criminal Defense, even small civil Litigation in the Bay Area particularly Monterrey itself it is likely a good option for the right person.
Put another way, if you have a Harvard JD you could clerk for a Federal Judge or have the option of representing SSI claimants if that's your cup of tea; unranked and lower ranked school graduates don't have the same band width of options. The lower ranking your school, the fewer options you will have straight out of school. However, in the scheme of things helping SSI claimants may indeed do more good for society than being the hatchet person for a corporate schill judge or an insurance company or god forbid a bank!
