Company Logo






Grand Rapids Reserve Supply was formed in 1930 as a reserve warehouse which distributed building materials to lumber and brickyards throughout Grand Rapids, Michigan. Previously owned by 30 area lumber dealers, the company was acquired by Nick Monsma in 1972. Nick changed the company’s name to Monsma Lumber shortly thereafter.

Initially distributing mostly commodity products, Monsma Lumber began focusing more on specialty building materials, and the current name of Monsma Marketing Corporation was born.



Adding hearth products to Monsma’s already broad array of offerings in 1990 was another growth step for Monsma. Our Hearth Products division now serves customers in 25 states and represents 28 product manufacturers. Monsma’s growing premium product mix is backed by dedication to excellence in product knowledge, service, delivery, and follow through by staff who have grown Monsma to be one of the nation’s most well respected building material and hearth product suppliers.

As much as Monsma focuses on excellence in distribution, we are also proud of our legacy. We remain family owned, with both second and third generations involved in the company who are committed to the same standards of trust, reliability and friendships upon which Monsma continues to be built.

2023 - Present


In 1999, Monsma moved just down the road from its previous 45,000 sq. ft. facility on Buchanan Avenue in Grand Rapids, Michigan. We continue to add to our much larger and more efficient location at 2450 Buchanan Avenue, SW. This 16-acre property presently contains a 200,000 sq. ft. facility with ample space for our fleet and additional outside storage.

In 2023, Monsma added a second distribution center dedicated to servicing our hearth products.  This adds an additional 60,000 sq. feet of warehousing space and gives us plenty of room to expand to our product offerings, and further enhances our abilities to service our customers throughout the Midwest and beyond.

Today & The Future


Today, Monsma focuses on being a premium two-step distributor for the Building Material and Hearth Industries as we continue to grow our footprint. Supplying premium, branded products with a dedication to excellence in product offerings, product knowledge, dedicated service, and prompt and accurate delivery, allows Monsma to be THE choice for your building material and hearth product needs.
