Who We Are

Feel secure knowing someone is watching over your property

with Detailed Services from Our Security Officers


Trust in our security officers for superior on-site security and patrol services that enhance the safety of your property. All security companies are not alike, and no company shows this to be truer than Guardian Security Agency. After asking other business owners what they wanted from their security services management company, we found the answers we needed to create our procedures and team of security officers. Now, our company stands alone in offering you unmatched security services at affordable rates.


Who Are We?

Guardian Security Agency was one of the founding members of CALSAGA (California Association of Licensed Security Agencies, Guards and Associates) and is currently a member in good standing. We’re committed to being on the cutting edge of today’s “new breed” of security agencies. Our management team uses more than 30 years of combined law enforcement experience and more than 40 years of combined personnel management experience to attract and retain the finest, highest caliber security professionals available.

Guardian is proud of its reputation for providing the finest security services in the area. We take great care in our hiring practices. All security officers are required to complete our 40-hour training class, which is very similar to the one used by California since 2004. In fact, our management team helped the state develop its program using programming very similar the model we’ve been using for more than thirteen years.Obviously, with their background and required training, our patrol officers are far better equipped to deal with the problems unique to today’s security needs than most security officers currently available through other companies. By developing and adhering to high standards for recruiting and screening, Guardian can provide you with mature, responsible professionals who will present a proper image while providing the necessary security services.


A Word from Our President, David J. Travers

I’m the president and qualified manager of Guardian Security Agency, but I’m also a co-founder of Delta Personnel Services, Inc. Guardian Security Agency was created as a result of my long-standing interest and affiliation with law enforcement and emergency services since 1971. My background includes service as a firefighter and EMT in New Hampshire, as well as working for a private investigative firm in Massachusetts.

I was also a per diem police officer serving as an undercover narcotics investigator. In California, I served as a reserve deputy sheriff in Alameda County, assigned to their mounted patrol unit. I recently retired from the Contra Costa County Sheriff’s Department where I served for 13 years as a Level 1 Reserve Deputy Sheriff.

We founded Guardian Security Agency to address a need in the industry for a more responsive, focused security services provider that would be responsive to the needs and concerns of its’ clients.

Our company is committed to listening to the needs of our clients and to providing the best possible service to address those needs.  We believe effective, continuing cmmunication is the key to a successful relationship between client and provider.  Our management team and supervisory staff are focused on each client to assure they receive the attention they deserve and the quality service they desire.  Our success is based on treating our clients and our employees the way we would like to be treated ourselves.
