ABC Bonding was founded in 1969 and has been continuously serving Central Coast individuals who have been arrested and are eligible for bail.

On June 1, 1993, Gregory L. Sullivan purchased ABC Bonding. His main goal has been and continues to be to differentiate himself from his competitors in San Luis Obispo as virtually all bail bond companies charge the same premium to bail a person charged with a crime. He believes professionalism and service are the ways to offer more to his clients. So, on May 1, 1994, Mr. Sullivan became the first bail bond agency to open an office in downtown San Luis Obispo. Soon thereafter, ABC Bonding joined the California Bail Agents Association and the Tri-Counties Better Business Bureau.

ABC Bonding is fortunate in that a majority of its business comes in the form of referrals from the legal community. To allow its agents to better serve attorneys and their clients, on January 15, 2001, ABC Bonding moved across the street from San Luis Obispo County Courthouse to 948 Santa Rosa Street in a new professional office setting. Our slogan remains: "It is better to know us and not need us, than to need us and not know us". Now you know us, and our new convenient location. We do appreciate your business!
