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.”
“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.”
“It’s a great company to work for… they really do care about their employees.”
“I have been working for STT for a year and a few months now, and I can honestly say I have never worked for a better company. The owners and site supervisors I have encountered have always treated their employees with the utmost respect and dignity.”
“Great company to work for; the owners are hands on. They care about their employees. Great work quality of life.”
“STT definitely knows how to get the job done no matter what the tasks are. Easy going with clients and well-managed officers. STT is a wonderful company to consider when it comes to safety and investigations. To those looking for a change of employment, I recommend giving STT a try.”
“It is refreshing to know that STT’s corporate staff really appreciates and supports their officers.”
“Adaptive, growing company with diverse opportunities and employee-centered business philosophies.”
“A wonderful place to work, good hours, all shifts available. Great leadership, good pay.”
“STT has been one of the best companies I have ever worked for… Corporate leadership is always helpful and honest… If you are serious about a career in law enforcement or security-related fields, you will not find a better organization to work for.”
“The management team [at STT] genuinely cares for their employees and does what they can to keep a balanced work life.”
“The STT personnel I recently worked with at a Michigan festival were friendly, well turned out, and interacted well with both festival staff and attendees. They provided insight and a good solution to one potential incident before it became something more – highly recommended.”
“Very pleasant to work with. Staff did an excellent job at our event.”
“We appreciate the wonderful customer service, attention to detail, and the added security you provide to us and our residents. Keep up the great work!”
