About Us
From Family Roots to Solid Foundations
Mammoth Construction & Woodworks is led by owner Ries Meyer, a second-generation craftsman carrying forward a legacy of skill and integrity. His father, Derek Meyer, has worked in construction since 1996 and passed down the knowledge, grit, and values that define Mammoth today.
With Derek’s decades of experience as a foundation, Ries built Mammoth into a company known for craftsmanship, reliability, and the belief that a job worth doing is worth doing right. Under Ries’s leadership, Mammoth has grown to take on everything from custom woodwork to complex hillside builds—always with the same dedication to quality and care.
At Mammoth, we’re not just building homes—we’re building trust, family legacies, and work that stands the test of time. Proudly serving the Greater Seattle area, King & Snohomish Counties.
