Hi! I started as a new grad and worked at Mayo for four years until I moved away. My husband (who also worked there) and I agree that Mayo is the best. The ratios are great: 1:2 or 1:1 (sometimes 2:1) in the ICU and Intermediate, 1:3-4 in Cardiac Progressive, and 1:4 everywhere else, from what I remember. It may have been possible to have 5 patients at night on a med/surg/tele floor, but I think it was an exception rather than a rule. People really care about the patients and put them first. You see a lot of really interesting patients, diagnoses, and surgeries. Their minimum pay rate for RNs right now is $35.41(per their job postings), so I would imagine you could earn quite a bit more with 13 years of experience. We left AZ because the heat sucks, but have recently started discussing coming back just to work for Mayo again, it's that great of a place. Good luck with your search!
