Aspen Highland Partners

Aspen Highland Partners was established in 2011 by William C. Powers and his spouse, Marianne Elmasri, in Snowmass Village, Colorado. The firm originated to manage wealth accumulated over Powers's career as a Managing Director at PIMCO and subsequent private-equity leadership roles. Elmasri, a co-founder of the office, is active in regional cultural institutions including Jazz Aspen Snowmass and the Los Angeles Philharmonic. The investment strategy spans both public and private markets, allocating to direct co-investments and special-purpose vehicles across technology, energy transition, and real estate. Confirmed active positions include the Miami Worldcenter mixed-use development in Florida, a residential estate at 1473 North Ocean Drive in Palm Beach, and a stake in Arca's digital-asset platform. The office also reports a natural-resources and commodities portfolio alongside a collectibles book. Sandbridge Capital, co-founded by business partner Ken Suslow, serves as a venture co-investment vehicle that counts Tommy Hilfiger among its advisors. The firm operates from Snowmass Village with a real-asset footprint extending to South Florida. Powers maintains professional network ties through the Princeton Varsity Club and Stanford Graduate School of Business Dean's Advisory Committee. Philanthropic engagement flows through the Kennedy Center, the Frist Art Museum, and Princeton University Athletics, with Elmasri serving as Chairman of Jazz Aspen Snowmass. Powers currently conducts principal investing activities through the office without disclosing an external team headcount or total deployment figures. What distinguishes the office is its hybrid architecture: it operates as a single-family fiduciary while actively deploying capital through Sandbridge Capital, a separate venture platform with dedicated external partners. This creates a dual-track structure where family capital can move alongside institutional co-investors in consumer and technology deals — an arrangement that blends SFO privacy with collaborative deal-making capacity.
