Since our founding in 1971 by George F. Medina Sr., we have been rooted in California, operating from our corporate office in Buena Park, in northwest Orange County.

The roots of PCS trace back to the mid-to-late 1960s, where George Sr. first began his long and accomplished career in the insurance industry with The Hartford Insurance and Mission Insurance. After laying that foundational experience, he built PCS from the ground up. Still highly active, George Sr. and his family remain at the heart of the business, united by an unbreakable commitment to client service and industry-leading quality. From its origins to its present form, the business's trajectory and character have been shaped by the family's generational influence.
