“Professional and the event went perfectly”

Diamond Security was great. I was able to schedule various security guards for an event with only 2 days notice. Everybody showed up, was very professional and the event went perfectly. I highly recommend Diamond Security Services to anyone who wants a low-hassle and fast way to hire security.
