Cedars-Sinai Hires the Hilton Foundation's CIO: How to Map Warm Paths When an LP's Chief Moves Between Institutions

On 6 October 2026, Cedars-Sinai announced that Michael Buchman will become its chief investment officer on 1 December 2026, leading an investment portfolio of about $8 billion. He joins from the Conrad N. Hilton Foundation, where he spent 18 years, has been chief investment officer since 2021 and has managed a portfolio of $8.3 billion. Cedars-Sinai did not name his predecessor, and as of 9 October we found no announcement of who will succeed him at Hilton. For a GP, that means two relationship books are changing hands at once.

What the announcement says

Cedars-Sinai said Buchman will oversee investment strategy, objectives and policies set by the investment committee of its board, advise on portfolio risk and exposure, and develop the investment team. Its chief financial officer, David Wrigley, said Buchman is the right leader to grow the portfolio strategically. At Hilton he reported directly to the chief executive. Before the foundation he worked in finance, real estate and law at Citigroup Global Investment Bank, Broadway Partners and two large law firms, and he holds a law degree from the University of Pennsylvania and an MBA and economics degree from Wharton.

His Hilton record matters for mapping. He was named co-CIO alongside Yatin Patel in November 2016, when the foundation's portfolio was $5.6 billion and Buchman's side covered private equity and real assets. Patel left in 2021 and Buchman became the sole CIO, with assets of about $6.7 billion. The portfolio is now $8.3 billion, which is 48% above its 2016 level, although that growth reflects markets and contributions as well as decisions. By our arithmetic, Cedars-Sinai's $8 billion pool is 96% the size of the one he leaves, so this is a lateral move in scale rather than a step up in assets.

How this compares with other recent moves

This is the second health-system CIO appointment we have covered since 29 September, after Northwestern Medicine's new chief investment officer. It differs from the Mellon Foundation's internal promotion in one way that changes the mapping work. A promotion keeps the existing book of managers and changes the person who reviews it. An outside hire brings a second book, so the same individual can be a warm path to managers at his old institution and a new decision maker at his new one.

Map both books before you reach out

What follows is our advice, not something either institution said. Start with a relationship ledger, a simple list of every person in your network who has dealt with Buchman at Hilton: co-investors, other LPs who sat beside Hilton in your funds, consultants and former colleagues. The point is to find the person who can speak for you, not to find a way around them. Check your own investor list and the public fund announcements of peers you respect for any fund that Hilton has backed, because those managers know how he runs a diligence process. Funds with an LP advisory committee are worth checking first, since members who sit beside each other tend to know one another's diligence habits and can say how a given investor behaves after it commits. A warm introduction from a peer GP who has been through it carries more weight than one from an intermediary who has not.

Next, map the Cedars-Sinai side. The announcement names the board's investment committee and the chief financial officer as the parts of the institution that set policy and sponsor the role, and it says the investment team will be developed. That makes later hires at Cedars-Sinai as informative as Buchman himself, and our note on how to follow LP staff moves into warm paths covers how to track them. Our guide to building a warm path to LPs sets out the wider method.

Mind the timing

Until 1 December Buchman is still the Hilton Foundation's chief investment officer, so a pitch that mentions Cedars-Sinai now puts him in an awkward position. Congratulations through a mutual contact are fine. Detailed fund discussions are better held until he is in the seat, and our view is that new chief investment officers usually spend their first months reviewing the portfolio and policy before taking on new managers, so the first quarter of 2027 is a more realistic window. The announcement gives no asset allocation, private markets share or ticket size for Cedars-Sinai, so do not assume a fit with your strategy until you have seen how the portfolio is built.

Alumni ties are a fair opener but a weak basis for a relationship. If your team includes Wharton or Penn Law graduates, tell the person making the introduction, then lead with the strategy and the data.

What to watch next

Watch for the Hilton Foundation naming its next chief investment officer, because that seat controls an $8.3 billion relationship book of its own and will open a second door. Also watch for the first investment team hires at Cedars-Sinai after 1 December. FundLinx members can see who has worked with which LP decision makers before approaching either institution.
