S.K. Hart Management

Khosrow Semnani established S.K. Hart Management in 1997 after building Envirocare into a nuclear-waste disposal business with contracts from the U.S. Department of Energy, Department of Defense, and Environmental Protection Agency. The firm operates exclusively for the Semnani family and maintains its headquarters at 630 East South Temple in Salt Lake City. The portfolio mixes marketable securities, real estate, private equity, private credit, natural resources, and philanthropic vehicles. Holdings include Trolley Square Shopping Center in Salt Lake City, Bayview Corporate Center in Newport Beach, agricultural ranches in South Africa through S K Hart Ranches (PTY) Ltd, and direct stakes in energy development projects. Confirmed positions and board ties reach Perma-Fix Environmental Services and Subsurface Technologies. Geographic reach covers North America, Africa, and Asia. Bauback 'Bobby' Kia previously worked at the World Bank International Finance Corporation and now advises Capital for Climate while co-founding Global Deployment Partners. The team includes Director of Investments Tom Bunce and Property Manager Mandy McKenna. Former CFO Larry M. Shelton served from 1999 to 2018 and remains chairman of Perma-Fix. The firm belongs to the Salt Lake Chamber and maintains ties to NEXUS Global, CREO, and Tiger 21 networks. It supports the Semnani Family Foundation along with Maliheh Free Clinic, Oxfam, UNICEF, and the World Food Program. No operational events from the last 24 months appear in available records. S.K. Hart Management keeps a hybrid structure that combines direct operating-company ownership with advisory relationships to external platforms such as Capital for Climate. This setup allows family principals to retain board seats and co-investment access while separating philanthropic vehicles from the core investment mandate.

Frequently asked questions

Who runs investment decisions at S.K. Hart Management?

Bauback 'Bobby' Kia serves as Advisor to the CIO and leads climate and impact strategy. Tom Bunce holds the title of Director of Investments. Khosrow Semnani remains the founder and principal decision maker for the family office.

How does S.K. Hart Management source proprietary deal flow?

Family principal Bauback 'Bobby' Kia convenes co-investment roundtables through prior work at the World Bank IFC and current ties to Rockefeller Capital Management and NEXUS Global. Direct board relationships at Perma-Fix Environmental Services and Subsurface Technologies provide additional access.

Is S.K. Hart Management structured as a single family office or does it operate more like a venture firm?

The firm functions strictly as the single-family office for the Semnani family. It deploys capital through direct co-investments, SPVs, and operating-company stakes rather than raising external funds.

Does S.K. Hart Management participate in fund commitments or only direct deals?

The office uses direct co-investments, SPVs, and ownership of operating companies. It also allocates to hedge funds and private credit but maintains no disclosed commitments to third-party funds.

What investment stages does S.K. Hart Management typically target?

The firm targets early stage, seed, Series A, and Series B opportunities alongside later-stage direct investments in energy and real estate. Confirmed technology focus includes biotech and ESG themes.

Where does the underlying wealth come from?

Wealth originates from Khosrow Semnani's founding of Envirocare, a nuclear-waste-disposal facility that served U.S. government clients. The family office manages proceeds from that business plus subsequent real estate and operating-company holdings.

Does S.K. Hart Management maintain philanthropic structures, and how are they separated?

The Semnani Family Foundation operates alongside vehicles such as the Global Solution Deployment Endowment, OneKind Act a Day, and The People's Prize. These entities remain separate from the investment portfolio while sharing family oversight.
