What G. L. Seaman & Company does

G. L. Seaman & Company (GLSC), founded in 1984 in Dallas, Texas, is a privately held, woman-owned commercial furniture and interior construction dealer serving the Dallas-Fort Worth metroplex and broader North Texas region. The firm is a MillerKnoll Certified Dealer and one of the Top 5 Knoll dealerships in North America, having maintained Knoll President's Circle status for ten consecutive years; it distributes Herman Miller, Knoll, Geiger, HAY, and NaughtOne product lines alongside modular interior construction systems from DIRTT (a Premier Partner) and ALUR frameless glass walls. Its technical stack centers on the Configura CET Designer 3D rendering platform for its proprietary Co-Design process, DIRTT's ICE virtual-reality visualization tool for connected design-to-manufacturing workflows, and ALUR's floor-to-ceiling glass wall systems, enabling real-time budget updates and immersive client design sessions.

GLSC operates four showroom locations across DFW (Dallas headquarters, Fort Worth design district, Plano DIRTT Experience Center, and the first MillerKnoll-branded showroom in Dallas) and delivers projects end-to-end through in-house design (18 credentialed designers), project management, and installation teams (technicians averaging 20+ years of service), eliminating third-party subcontractor handoffs. Revenue is generated across five streams: one-time furniture sales, interior construction project work (DIRTT modular walls, millwork, power and networks), installation services, design services under the Co-Design methodology, and recurring Day 2 managed services (asset management, storage, reconfiguration, and move/relocation).

The go-to-market is primarily enterprise field sales targeting corporate, legal, healthcare, government, and education clients — sectors where named logos include Texas Pacific Land, Diamondback Energy, Willkie Farr & Gallagher, Katten, the City of Weatherford, TCU Burnett School of Medicine, Allied Electronics, Sovereign Bank, Weir Oil & Gas, and TGI Fridays — augmented by inside sales, showroom engagement, and CEU events targeted at the Architecture & Design community. Pricing is quote-based for furniture and project work; payment processing supports electronic transfers up to $75,000 and credit card payments with a 3.0% service fee. The firm holds WBENC, NCTRCA, and Texas HUB certifications that qualify it for government and corporate supplier-diversity procurement.

• Kimball International: Office furniture manufacturer offering premium and mid-market brands (Kimball, National, Etc.) that compete for similar workplace, healthcare, and education contracts. Comparable in the broader office furniture value chain.
• Haworth: Global office furniture manufacturer competing directly with MillerKnoll/Knoll in the same premium segment GL Seaman serves. Comparable insofar as it shapes the supply side of the dealership model and the broader competitive landscape.

Others
