ATC Partners

What ATC Partners does

ATC Partners, LLC is a privately held, full-service commercial real estate investment and development firm founded in 1992 by Michael Halper and headquartered at 1000 Sansome Street in San Francisco. The firm targets older buildings and distressed properties in prime Bay Area locations, repositioning each through acquisition, state-of-the-art renovation, leasing, and day-to-day management to maximize value. Its current portfolio comprises four core assets: 1000 Sansome Street (62,000 SF creative office in San Francisco's North Waterfront), San Bruno Office Park, West Valley Executive Park (126,000 SF across four two-story buildings in San Jose), and Stevens Creek Executive Park (164,000 SF mixed-use in San Jose, formerly Meridian Square). The company serves small and mid-sized professional businesses — including advertising, software, and real estate firms — seeking distinctive, amenitized office space at Bay Area submarkets, with selective exposure to retail tenants (notably The Gap in Oakland's Downtown, recognized as 'Best Retail Deal 2000').

The business operates on three revenue streams: one-time gains from property sales (e.g., South of Market 2011, Burlingame 2013), recurring rental income from leasing repositioned office space, and ongoing property management fees. Distribution relies on a direct in-house leasing team and LoopNet marketplace listings; marketing is primarily through the company website and Nina Phan's tenant development/retention function. There is no proprietary technology stack, no app, no public API, and no AI/ML capability — the firm runs on relationship-driven deal sourcing and hands-on asset management. The team consists of five named members (CEO Halper, COO Tom Keane, Portfolio Analyst Emily Benton, Marketing/Leasing Specialist Nina Phan, and Property Manager Jon Royce), consistent with the 11-50 employee band. Historically active in Oregon (Beaverton, Portland) and the broader Bay Area (Walnut Creek, Burlingame), the current portfolio is concentrated back in San Francisco and San Jose, with the firm operating in steady-state/harvest mode based on the disposition-heavy 2011-2013 news record and absence of disclosed subsequent acquisitions.
