Peterson Garrett

The wealth was generated by Peter G. Peterson through his co-founding of The Blackstone Group in 1985. Peterson served as the firm's chairman and held a substantial equity stake. Upon his retirement from Blackstone in 2008, he liquidated his majority position, creating the liquidity event that capitalized the family office.

The family office and the foundation are separate entities with distinct purposes. The Peter G. Peterson Foundation was launched in 2008 with a $1 billion endowment to promote US fiscal sustainability. The family office manages the family's private investment portfolio independently of the foundation's programmatic work.

No. Peterson Garrett functions exclusively as a single-family office for the Peterson family. It does not manage third-party assets, market to external LPs, or offer investment services to other families.

The office pursues a preservation-first mandate with a long time horizon. Its portfolio allocates across public equities, private equity fund commitments, hedge funds, and select direct investments, with a geographic focus on North America and developed Europe. The style is consistent with a deeply value-oriented, cycle-agnostic philosophy.

Given the office's lean internal structure and the principal's legacy as a fund general partner, Peterson Garrett likely participates in co-investment opportunities offered by its existing fund managers, but there is no public record of the office soliciting or leading co-investment syndicates.
