Heiser Investment Advisers

Thomas J. Heiser co-founded Heitman in 1966 and the real estate investment manager remains the primary source of the family office's wealth. Heiser Investment Advisers is a separate entity, but the two share DNA — the family office allocates capital to direct real estate and likely co-invests alongside Heitman-managed vehicles, creating a sourcing pipeline unavailable to unaffiliated investors.

Thomas J. Heiser is the named principal, though the office's internal governance structure is not publicly disclosed. Given the office's low profile and single-family orientation, investment authority likely sits with Heiser or a small internal committee, potentially supported by external managers for public securities and fund commitments.

No. The firm operates as a single-family office serving the Heiser family. It does not solicit or manage third-party capital, and it does not appear in regulatory filings as a registered investment adviser with external clients.

Real estate is the core allocation — consistent with the Heitman origin story — spanning direct property investments and fund co-investments. The office also makes commitments to private equity funds and maintains a public securities portfolio for liquidity management, though the precise weighting across these buckets is not public.

The office operates from Chicago, Illinois — the same city where Heitman's global headquarters is located. This co-location facilitates close coordination between the family office and the institutional investment platform that generated the family's wealth.
