Pinnacol Assurance celebrates 70 years of partnership with iconic Colorado members

DENVER - May 20, 2026 — Pinnacol Assurance, Colorado's leading workers’ compensation provider, is proud to celebrate a landmark 70-year milestone with 122 of its longest-standing members. Since 1956, these organizations, spanning municipalities, fire districts, and local governments, have partnered with Pinnacol to build safer workplaces and support Colorado's economy. These members represent the fabric of Colorado and are located in every corner of the state.

“For seven decades, these communities have trusted us to protect their most valuable asset: their people,” said John O’Donnell, president and CEO of Pinnacol Assurance. “This celebration is about more than just longevity; it’s about a shared, unwavering commitment to the safety and well-being of the employees who keep our cities running, our fires extinguished, and our local economies humming.”

Since first joining Pinnacol in 1956, these members have demonstrated exceptional dedication to workplace safety.
