Due to the specialized nature of our applications work – we do not represent any off the shelf, stocked components. We are neither distributors nor brokers – but extensions of our principals’ sales & marketing staffs. We provide application-engineering resources to research and product development groups. As new technologies are introduced, we take advantage of opportunities to improve output and efficiencies in the manufacturing areas.

This web site gives you an overview of our services and products, as well as links to helpful sites. Please contact us with questions on specific projects. We’re here to help in every way we can.


Flying into the Diablo Valley

About Us

Diablo Sales & Marketing provides broad-based, customer-focused engineered material solutions.

Headquartered in Diablo, California – approximately 30 miles from the Silicon Valley and San Francisco – we currently have 7 offices covering the western United States and western Canada. The company was founded in 1987 in the San Francisco Bay Area foothills of Mt. Diablo State Park, which inspired our name.

Ari Kettunen, the founder, has over 30 years of technical sales experience with custom engineered materials and performance polymers. Our Sales Engineers are seasoned professionals with degrees in Mechanical Engineering and/or the Sciences.

We are proud to be exclusive representatives of a limited number of quality, innovative and financially sound companies. All Diablo suppliers are chosen for their ability to respond quickly to small prototyping projects and ramp up to larger production volumes.
