Frequently asked questions
Where does the underlying wealth come from?
The Sisung family fortune was built through the Sisung Group, a New Orleans-based operator of offshore supply vessels and maritime services for the Gulf of Mexico energy industry. The group owns and operates crew boats and platform supply vessels that service deepwater rigs and production platforms, generating revenue under long-term charter contracts with major energy producers.
How is the investment office structured relative to the operating business?
Sisung Investment Management Services is not a standalone allocator — it is the investment arm embedded within the Sisung Group, with the same leadership overseeing both the maritime operating companies and the family's investment portfolio. Capital for new investments is sourced from operating-company cash flows rather than outside limited partners, giving the office a permanent-capital posture and no redemption pressure.
What does the office's real estate portfolio focus on?
The office's real estate investments concentrate on commercial properties in Louisiana and the broader Gulf South region. The strategy favors income-producing assets with long-term tenant profiles, consistent with the family's preference for asset-heavy, cash-flowing investments rather than development speculation.
Does the firm take outside capital or operate as a multi-family office?
No. Sisung Investment Management Services manages capital exclusively for the Sisung family. There is no indication the office has opened to external investors, joined co-investment clubs, or converted to a multi-family office structure.
Is the office directly involved in operating the vessel fleet?
The investment office and the operating company share leadership under David Sisung, meaning capital allocation and vessel-fleet management are not siloed. Investment decisions are informed by direct operating knowledge of maritime logistics, crew deployment, and energy-sector charter markets — an informational edge that a pure financial allocator would lack.
