About PIA

Two Generations of Expertise

Established in 1960 by Sterling L. Hammack Jr., PIA was founded on the principle that each customer is entitled to the highest standards of industry expertise and hands-on service. Today our network of more than 250 affiliated offices throughout California and Nevada hold to those same high standards, providing clients with diverse strategies and resources in the full range of insurance needs.

We pride ourselves finding the ideal insurance “fit” by designing the most cost-effective protection plans through our access to worldwide insurance markets. Customers—both individuals and businesses—benefit from a choice of coverages to meet their unique insurance needs. We partner with more than 40 home and automobile companies, and more than 100 commercial entities to offer the broadest range of options possible.
