McKenna & Sullivan

John McKenna and Michael Sullivan co-manage all investment decisions. Each has over 20 years of experience in investment banking, with McKenna at Goldman Sachs and Sullivan at J.P. Morgan, and they personally source and approve every deal.

The firm sources deals directly through the principals' networks from their time at Goldman Sachs and J.P. Morgan, as well as through relationships with infrastructure and credit funds such as Stonepeak and Apollo. They do not use intermediaries or external placement agents.

McKenna & Sullivan is a single-family office, managing capital exclusively for the McKenna and Sullivan families. It does not accept outside third-party capital.

The firm focuses on direct investments in mature infrastructure and private credit, typically requiring equity checks between $10 million and $50 million. They avoid early-stage venture or public equities.

The firm primarily executes direct co-investments alongside institutional partners, but it has also made limited fund commitments in infrastructure and credit strategies (per public record). The balance leans heavily toward direct deals.

Wealth originates from John McKenna's career as a senior executive at Goldman Sachs and Michael Sullivan's as a managing director at J.P. Morgan, where they earned compensation before founding the office in 2012. The families' combined wealth is managed within the office.

Yes—the McKenna & Sullivan Foundation, which focuses on education and veterans' issues, is a separate legal entity from the family office. The foundation is funded by annual contributions from the family office but operates under an independent board (public record).
