Regardless of what I might say about them when they do something I disagree with, they are the ones to call if you are looking for that kind of work.
The Atlantic Group has a few contracts too, but not as many and I have never worked for them. so I cannot offer an opinion as to whether they are good or bad to work for. 800-332-0058
If you are looking for work in specialty decon (the kind with machines and processes - not masslinn mops) call Babcock Services/IceSolv 401-823-1796
Good luck
