Our security officers are proud beacons in their respective communities. They are involved in many local charitable causes and foundations such as:

"Kindness is the language which the deaf can hear and the blind can see," Mark Twain

"We keep moving forward, opening new doors, and doing new things, because we're curious and curiosity keeps leading us down new paths," Walt Disney

"A good job is more than just a paycheck. A good job fosters independence and discipline, and contributes to the health of the community. A good job is a means to provide for the health and welfare of your family, to own a home, and save for retirement," James H. Douglas, Jr

"Without a sense of caring, there can be no sense of community," Anthony J. D'Angelo
