You'll never make more as a nurse than you will in NorCal. Dignity doesn't pay quite as well as Kaiser or Sutter, but you'll still be starting out at $50+/hr, probably more. Sutter starts at $60ish for newer nurses (I make about $80 there now per diem), and I'm making $96/hr benefited (that includes the $12 night differential) at Kaiser with 6 years experience. Per diem at Kaiser averages $100/hr plus differential, depending on experience.
Bottom line- take any job here. You can always transfer out of Dignity in the future.
