GMS / Parent Company

A nationwide network of distribution centers, and success.

Both New England Gypsum (NEG) and the Robert N. Karpp Company (Karpp) are proud to be part of the industry-leading Gypsum Management and Supply (GMS) family of companies.

GMS opened its doors in 1971 in Atlanta, Georgia.

Gypsum Management and Supply was founded by two partners who prided themselves on building a company comprised of local subsidiary partners with a vested interest in their business and local communities. New England Gypsum and Karpp are among many local subsidiary partners in our network of 200+ distribution centers that spans more than 40 states nationwide, and now includes locations in Canada. Our unique service model combines the benefits of national scale with a local “go-to-market” strategy. Using an integrated national platform, we operate local companies with solid reputations, strong relationships, and local expertise.

GMS is the largest distributor of drywall products in the United States and a leading distributor of steel framing, insulation, acoustical ceilings, EIFS, joint treatment and finishes used in both commercial and residential applications. Currently, GMS and its subsidiary companies distribute over 40,000 unique products including a wide range of accessories and tools.

We take pride in knowing that our employees are among the most knowledgeable in the industry. At GMS, we empower employees to focus on their customers, and doing whatever it takes to exceed expectations and provide superior service. Our guiding principle has always been that you can never go wrong doing the right thing.
