ASG Security was founded in 2002, on the belief that we could build a customer focused company superior to what exists in the electronic security industry today. Bigger doesn’t always mean best. We understand that. By design, our business model ensures that we know who our customers are; what they expect and hire employees dedicated and focused to this end. I take pride in knowing that each and every customer is just a short reach away, and I make myself available directly too their needs. Our customers, branch offices are clustered closely inside three distinct operating areas – the Mid-Atlantic region (Washington DC/Baltimore, Virginia and Boston MA), throughout the State of Texas and in the Carolinas. The resources we offer our clients are strong and nearby. Our management teams are experienced and all share a passion, dedication and unwavering commitment to customer service. ASG is by no means small. We are 130,000 customers strong and growing. In May 2009, ASG Security was recognized as the 11th largest U.S. security company (Source: SDM Magazine, May 2009) and we were awarded SDM's "Dealer of the Year" in December 2008 for the 2008 calendar year.
