Green Diamond Resource Company

We are Green Diamond
Management Company.

We provide forest management services for working forest owners and their investors. We offer a suite of services:

  • Management to enhance and ensure the health and productivity of forests
  • Marketing and sales to ensure value for the landowner
  • Services to support evaluation, acquisition and sale of forest lands

Our roots run deep. Green Diamond Management Company is a subsidiary of Green Diamond Resource Company, owner and manager of over 1.3 million acres of working forests. Ours is a long-term view, dating back to 1890, when our founder Sol Simpson started Simpson Logging Company in the Pacific Northwest. Our foresters, scientists and other managers take a hands-on approach, considering every land management decision to ensure health and productivity both now and into the future.

As we take responsibility for managing 381,000 acres of highly productive forest land in the south and west, our goal is to be a preferred provider of logs and wood fiber certified to the Sustainable Forestry Initiative® Standard. Call on us.

If you’d like to put your skills to work managing working forests with a long-term view, we’re hiring. Join us.

Green Diamond Management Company. We’re setting the standard in working forests.
