## About

Dille & Koo was established in 2016 as a California-based multi-family office. The firm's operating infrastructure is intertwined with the Rodan family. Katie Rodan and Dr. Kathy Fields and ultimately acquired by Estée Lauder. The Rodan Family Foundation officially lists its contact address in care of Dille & Koo, signaling a deep operational relationship where the investment office serves as a fiduciary and administrative backbone for the founders' philanthropic activities. The firm deploys capital across buyout, growth, and venture stages, with a primary sector emphasis on luxury. Its investment scope is defined by a mix of collectibles and passion assets alongside direct co-investments and special-purpose vehicles in private equity. Confirmed geographic focus remains concentrated in North America. Dille & Koo operates from a single office in Orinda, California. Public team disclosures reveal no named professionals, a posture consistent with a tight, low-profile advisory structure serving a restricted number of client families. The firm's footprint is solidified through its operational role with the Rodan Family Foundation, a key client and service relationship that positions Dille & Koo as the primary steward of the Rodan founders' financial and philanthropic affairs. No publicly disclosed adjacent vehicles or club memberships have been identified beyond the foundation relationship. Structurally, Dille & Koo occupies a hybrid space between a traditional multi-family office and a dedicated founders' office. Its concentration around a single named wealth originator — the Rodan family — and the integration of a philanthropic foundation under the same operational roof creates a closed-architecture model. This governance design functions less like an open-architecture MFO and more like an extended single-family office that selectively absorbs additional client families under its existing administrative chassis.

## Questions

### Who runs investment decisions at Dille & Koo?

Dille & Koo does not publicly disclose the names of its investment principals or leadership team. The firm presents a deliberately low-profile operating structure from its single office in Orinda, California. Its key relationship is with the Rodan family, for whom it provides integrated investment and administrative services, but the specific individuals executing investment decisions are not publicly identified.

### How is Dille & Koo related to the Rodan Family Foundation?

The Rodan Family Foundation lists its official contact address as 'C/O Dille & Koo, LLP' at the firm's Orinda office, establishing Dille & Koo as the foundation's administrative and accounting service provider. This arrangement integrates the family's philanthropic grant-making directly into the multi-family office's operational structure. It means investment management, wealth administration, and charitable giving are coordinated through a single fiduciary platform.

### Is Dille & Koo structured as a single family office or does it operate more like a venture firm?

Dille & Koo is formally a multi-family office, but its operating model heavily centers on the Rodan family and their associated foundation, making it behave more like an extended single-family office than a broad-market MFO. It does not operate as a venture firm or have a public fundraising cycle; its investments in buyout, growth, and venture stages are made through direct co-investments and special-purpose vehicles without the mechanics of a venture capital fund manager.
