Sean Flanagan’s career climbed steadily through blue-chip institutions before pivoting into entrepreneurship. He began at FirstBank of Colorado as a teller honing cash-management discipline, then widened his operational view in treasury accounting at Laramar Group during the post-recession real-estate shake-out. Nearly a decade at HSA Commercial Real Estate out in Chicago followed, where he advanced from property staff accountant to Vice President of Development & Acquisitions, helping deliver roughly eight million square feet of medical, retail redevelopment, and speculative industrial projects across six states. In 2021 he joined Broe Real Estate Group as Vice President – Industrial Development, steering a 300-acre Colorado logistics park with a rail-served cross-dock BTS anchor development and aiding master-planning a 1,400-acre Kentucky brownfield redevelopment. The institutional chapter culminated at a public REIT, where, as Vice President / Investment Officer for Denver and Reno markets, he directed capital deployment, land acquisitions, and large-scale strategies—including an 1,800-acre site on the California border he personally code-named project hotdog.

Since founding Flanagan Real Estate LLC in September 2023, Sean has shifted from corporate balance sheets to owner-representation and development-management consulting, pairing CPA-level underwriting with boots-on-dirt execution. Recent mandates span distressed office-tower acquisition advisory, personal investments in mixed-use retail development, rezoning and minor-subdivision work across metro Denver, co-GP structuring and debt syndication for multiple industrial projects (distribution, IOS, shallow-bay, and micro-flex), and conceptual planning for a 1,000-acre residential mountain lake community. The common thread: turning raw or under-utilized land and complex entitlements into bankable proformas and build-ready sites.

Parallel to his development practice, Sean serves as an associate broker with HydroSource, guiding clients through Colorado water-rights transactions and advising on resource-portfolio optimization. He also maintains ownership of a six-acre homestead that doubles as a living lab for water conservation and small-scale agriculture. Whether troubleshooting his own goat and sheep ranching wildfire mitigation business experiments or structuring multi-million-dollar water deals, Sean remains anchored by the same principles—disciplined numbers, imaginative land use, and a commitment to leave every watershed and community stronger than before.
