Mass General Brigham Retirement Plan

The Chief Financial Officer and Treasurer, currently Niyum Gandhi, holds ultimate oversight of the investment office. Until his departure in 2023, John Barker served as the dedicated Chief Investment Officer for 11 years and built the office's direct investment and manager-selection function. The office has not publicly named a replacement CIO, suggesting the function may now be embedded within Gandhi's treasury team.

The plan's most distinctive edge is spatial. Mass General Brigham is Massachusetts' largest private landholder and employer, which gives its investment team a proprietary view of clinical utilization trends, facility bottlenecks, and demographic-driven demand shifts across its own campus network. The direct ownership of 399 Revolution Drive in Somerville and medical offices in Palm Beach Gardens suggests the office uses system-level planning data — not broker-led marketing — to identify properties that align with current or projected clinical operations.

Both, but with clear delineation. The real estate sleeve contains direct property holdings: a commercial building at 399 Revolution Drive, a stake in a mixed-use Boston development, and medical office space in Florida. The private equity allocation is entirely fund-of-funds and primary fund commitments, concentrated in buyout strategies. The plan does not co-invest directly in operating companies or run its own portfolio of private companies.

The plan is concentrated in two pillars: private equity buyout funds and directly held commercial real estate. Within buyouts, the office commits across middle-market and upper-middle-market managers. The plan explicitly does not target venture capital, early-stage technology, growth equity, or opportunistic credit — a conservative posture consistent with a defined-benefit plan that must forecast liabilities against a unionized, aging workforce.

The retirement plan and the foundation are legally separate entities with different fiduciaries, beneficiaries, and spending policies. The foundation invests the system's charitable endowment to support hospital operations, research, and community health programs. The retirement plan invests to meet pension obligations for healthcare workers. The two vehicles likely share some manager relationships — particularly in real estate and private equity — but operate with independent investment committees and return targets.

The likely answer is asymmetric information. Mass General Brigham's clinical footprint makes it the most informed property buyer in its own market — it knows which neighborhoods need outpatient capacity before developers do. Holding medical office and commercial properties directly allows the investment office to capture the full property return without paying fund-level management fees, and to coordinate lease terms with the hospital system's own clinical strategy.

The plan's private equity program is structured around fund commitments, not direct co-investments. There is no public record of co-investment activity alongside its buyout managers. This is consistent with a plan that prioritizes fiduciary simplicity and manager diversification over the operational demands of co-underwriting individual deals.
