Employees and Clients Say…

Don’t just take our word for it – check out these reviews from current employees, clients, and alumni staff.

“I have worked in a lot of places. But I can’t think of one where I’ve admired and respected the employers more.”
Baltazar B.
“STT hired me before I was even off of Active Duty. For the 4 months I’ve been with them now, I’ve worked 2 sites in which the environment was great. Management recognized quality work immediately, and I was offered more opportunities I quickly took advantage of. I’ve met most of the good folks that make the company grow, and they would give you the coat off their back from my perspective.”
