You will need an RN license if your dream is to work in L&D. Even many RNs have extreme difficulty finding L&D positions because these jobs are so competitive and at a premium. Numerous nurses want to work in L&D, so RNs are given priority in hiring. I have never, ever seen an LVN hired into L&D in Southern California.
LVN salary in the greater Los Angeles area is $15 to $17 hourly for working in a doctor's office or outpatient clinic. The average hospital starts at $17 hourly, and nursing homes pay $18 to $21 hourly. Ventura, San Bernardino and Riverside counties pay the same as Los Angeles. I don't know about Orange County or San Diego LVN salaries.
I attended LVN school in the San Fernando Valley last year.
