Holy balls that's expensive!
Check out community colleges- they're WAY less expensive! I'm willing to bet that SF City College has a program, and I know Santa Rosa Junior College had a program last time I checked.
Take a look at the job prospects for LVNs in the Bay Area- they're dwindling, honestly. I don't see a lot of positions other than in SNFs. You may be better off looking at an ADN program. Just a heads up.
