About Our Company
Sierra Pacific Industries is a fourth-generation family-owned company based in Northern California that started in 1949 and has grown to be one of the largest lumber and millwork producers in the U.S., employing around 6,500 crew members. Sierra Pacific continues to be a company where its employees are proud to work at state-of-the-art facilities and others strive to become part of the team.

We own and sustainably manage more than 2.4 million acres of timberland in California, Oregon, and Washington. Our forests are sustainably managed under a 100-year plan by Registered Professional Foresters, Wildlife Biologists, Botanists, and other professionals. We are growing forests for our future, planting over 6 million new trees every year. In Spring 2024, we planted our 300 millionth seedling on our timberlands. This milestone was decades in the making, reflecting our commitment to sustainable forest management and ensuring we have forests not just for today, but for generations to come.

Sierra Pacific effectively uses nearly 100% of every piece of wood we bring to our facilities. In fact, any small amount that isn't turned into hand-crafted doors and windows, millwork, lumber, or landscaping material is actually converted into electricity in our eight biomass-fueled power plants.

We are proud that all Sierra Pacific facilities follow our drug-free and tobacco-free policies. As part of our safety in the workplace policy, an offer of employment is subject to a negative drug screen result. We use E-verify to verify the social security number and work authorization of all newly hired employees.
