Congrats on the decision to move back home. I was once in your situation. I am also a local growing up on the North Shore and attended UH Manoa. I eventually moved to the mainland and worked in various hospitals for over 8 years. I finally decided to move back home in 2006.
It sounds as if you want to work at a "laid back" hospital so Queen's would be out of the question. Working registry/agency right now is kind of sketchy. You will be canceled a lot due to hospitals trying to save costs and not use agency. Depending on your specialty, you could find work as agency if you were versatile and didn't care where you worked. The pay is usually a little better as agency and some agencies offer medical if you work the required hours. Here are the names of the agency if you're interested: NurseFinders, Specialized Nursing Services, Kahu Malama, Critical Nursing Services, Island Nurses, Altres Medical, and there are other smaller ones which I do not care to mention.
If you're interested in working on a Telemetry Unit, I could hook you up in a heart beat
, as long as you have the necessary skills and experience. Good luck on your decision!
