MB&G offers a comprehensive range of services in forestry, environmental, and geospatial services.

MB&G was founded in 1921 by David Mason, an early and vocal advocate for sustained yield forestry. He brought that passion to a wide variety of projects. Today, MB&G has three lines of business: forestry, environmental, and geospatial services. We are headquartered in Portland, Oregon, and have offices in California, Idaho, and Colorado. MB&G has 55 employees who provide forestry, environmental, and geospatial expertise to help solve some of the most complex natural resource management projects.

We provide outstanding service by getting to know our clients and understanding their business. Our core values are Integrity, Client Service, Quality, and Expertise. They are the key components of the work we do.
