Air Medical in New England
Boston Medflight located at Hanscom field (BED) has three rotor wings and one fixed wing, a Citation II. The Rotor wing outfit pilots are through Keystone aviation in PA and the Fixed wing side is through Boston Air Charter out of Norwood, MA (OWD).
I personally think it is an excellent place to work, very rewarding and a good cast of staffing to work with.
Best of luck in your pursuit.
Just keep in mind that there are times when you do not fly very much but when you do it is a very self fullfilling job.
Cheers
