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 am 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 communication 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.
