Hi,
Just saw you were going to work at St Mary's Hospital. My career started on the 3100 unit, cardiac/telemetry/neuro. I don't know if it still the same these days, was a great place to work. Left and moved to NC in 1998.
As far as the best living areas, the northern side of Tucscon was better as far as crime and things. I used to live not far from St Mary's off of Speedway. It was OK, did have a drive by near my house, that was one of the main reasons why I left, I had small children at the time, got scared.
I wish you the very best. I really loved working there!!!
