Marnell

What Marnell does

Marnell Companies is a third-generation, privately held family-owned enterprise headquartered in Las Vegas, NV, operating since 1974. The company is vertically integrated across architecture, design-build construction, construction management, commercial real estate, gaming ownership and operations, tribal gaming management, and transportation infrastructure. Its primary business delivers design-build services—integrating architecture and construction under one contract—to large-scale gaming and hospitality projects, having cumulatively delivered over $8 billion of work on landmark properties including Bellagio, Caesars Palace, Wynn Las Vegas, The Mirage, and Harrah's.

Beyond the design-build core, Marnell owns and operates hotel-casino assets (M Resort Spa Casino, plus remaining interests in Rio, Colorado Belle, and Edgewater), manages tribal gaming operations on behalf of Native American nations under NIGC-approved manager status, leases more than 700,000 square feet of commercial real estate across Southern Nevada, invests in non-gaming branded hotels (Hampton Inn / Home2 Suites JV at Morongo), and co-develops Brightline West, America's first high-speed rail connecting Las Vegas to Los Angeles in partnership with Fortress Investment Group.

The company makes money across six interlocking revenue streams: (1) construction and construction management fees (project-based, multi-year contracts, no public pricing); (2) gaming revenue from owned casino properties; (3) tribal gaming management and consulting fees including hotel operations, F&B, IT, and slot machine leasing; (4) commercial real estate rental income on the Southern Nevada portfolio; (5) non-gaming hospitality JV income; and (6) transportation infrastructure economics from Brightline West. Go-to-market is enterprise field sales, with direct executive relationships to major casino operators and tribal entities rather than external marketing channels. In September 2025, Marnell launched Marnell Howryla Architecture as a unified branded design offering; in March 2026, the company participated in a strategic seed investment in AEC design platform Skema.ai.
