Company History

1915 — Pinnacol Assurance was founded shortly after the Colorado General Assembly passed the Workers' Compensation Act.

During the mid-century, Pinnacol fulfilled its role as the assured source of workers' compensation coverage for all Colorado businesses, never turning away any organization regardless of size or risk — a role we continue to fulfill today.

1987 — Pinnacol's leadership team filed a "Plan for the Future" with the Division of Insurance and began focusing on customer service, fiscal discipline, and operational efficiency. The plan allowed the company to operate more entrepreneurially, and Pinnacol transitioned from a state agency to a quasi-public authority.

2004 — Pinnacol reached its surplus goals and assumed management of its $1.5 billion investment portfolio from the state treasurer's office.

2005 — For the first time in 23 years, Pinnacol distributed general dividends to policyholders. The distribution totaled $55 million, and over 90 percent of policyholders received dividend checks.

Today — Pinnacol is the carrier of choice for approximately 55,000 customers. Customer satisfaction is at an all-time high (8.7 points on a 10-point scale) and we're retaining 87 percent of our customers, due to our competitive pricing, personal service, and industry expertise. We support the families of injured workers through the Pinnacol Foundation, awarding nearly $3 million in college scholarships since 2000.
