Why You Should Consider Us?

Our employees fuel our success. Our security guards choose to work at our company because of our caring company culture, better training, better wages, and a respected management team. Our top notch training, professionalism, and the opportunity for promotion are part of the core values at our organization.

A typical security guard firm has two fundamental levels of employees: guards and managers. They normally hire managers from outside the company to sell and manage accounts, while hiring security guards off the street who are left with low pay, no benefits, inadequate training and no opportunity for promotion. The result of this is a substandard and unfulfilled position with no chance for a successful career. We really believe that even the newest security officer must have a true opportunity for success and advancement. Otherwise, there is no reason to stay with a job and commit to our organization.

You will be prepared for duty by our team of certified instructors. Here you will learn basic laws, basic defensive techniques including takedowns and handcuffing using the PPCT method, firearms, effective communications and report writing.

Blessed are the peacemakers: for they shall be called the children of God. – Matthew 5:9
