Pinnacol Assurance Celebrates 111 Years of Supporting Colorado's Workforce
On August 1, 2026, Pinnacol Assurance will celebrate its 111th anniversary alongside the State of Colorado’s Sesquicentennial milestone. Founded in 1915 as the State Compensation Insurance Fund under Colorado’s Workers' Compensation Act, Pinnacol has evolved from a state agency into a leading provider of workers’ compensation insurance for over 50,000 businesses across all sectors. Over its history, Pinnacol has adapted to support Colorado's economic transformation—from early industrial roots in mining and railroads to modern industries like technology and aerospace. Key milestones include the expansion of coverage beyond physical injuries in 1945, a shift toward proactive safety programs after OSHA was passed in 1970, and rebranding as Pinnacol Assurance in 2002. Pinnacol continues to innovate with digital solutions like Cake Insure for small businesses. It also supports the community through initiatives such as its $8 million scholarship program via the Pinnacol Foundation.
