    What they’re saying

    “In 2016 we briefly switched to a lower cost guard service, and in less than a year we had switched back to GMSC. Ours is a 2 million square foot Class A property with high service level expectations. GMSC staff, from the onsite guards to senior management, is professional and reliable. They have a strong onsite presence and a responsive and well-trained guard staff. We have been impressed with their flexibility and willingness to customize their protocol to meet the high standards of our tenant base.”

    Andrew Toland, General Manager, Cushman & Wakefield, 1211 Avenue of the Americas
    "In addition to giving excellent service at our Park Avenue South properties, GMSC has been especially efficient and effective in the way they distribute their staff. By more smartly allocating our guards they were not only able to increase security, but also save us money."
    Avi Itzikowitz, Director of Operations, Atco Properties
