Welcome to Peterson!

My name is Duane Doyle, and I’m the CEO and third-generation owner of Peterson. When my grandfather founded this company in 1936, he sold Cat® tractors in five counties in Northern California. Today, we’ve grown to become the authorized Caterpillar dealer to customers in over 100,000 square miles of California, Oregon, and Washington. In 2011, we became the Bay Area’s authorized International® Truck dealership, now serving a larger part of Northern California, Oregon and Southern Washington.

Our vision is to focus on you, the customer: “We will be our customers’ first choice.” Our mission is to be the best in all we do: Peterson partners with our customers in building the future. We put our customers first and continually strengthen our partnerships through hard work, ingenuity and determination. We provide a family-oriented environment that promotes safety, personal growth and professional achievement. Our people commit themselves to exceed the expectations of the customer, Peterson and each other. We will remain true to our values and set standards of excellence in everything we do.

At Peterson, we offer a wide range of trucks and services because we understand how complex and competitive your business is. We want to make buying and maintaining trucks easy for you. We prepared this information to show you the range of products and services we can deploy to help you succeed.
