Millbrook Capital Management

Millbrook Capital Management

Millbrook Capital Management was established in 1981 by John S. Dyson. The firm manages multigenerational capital originating from the Dyson family's stake in Dyson-Kissner-Moran and from winery operations. Robert R. Dyson serves as Chairman of Dyson-Kissner-Moran and the Dyson Foundation. The firm targets buyouts and early-stage investments across manufacturing, business services, and agriculture. It structures transactions as direct co-investments and private-equity holdings with principal capital only. Confirmed positions include Millbrook Vineyards & Winery in New York and Williams Selyem Winery in California. The geographic footprint centers on North America with additional holdings in Tuscany, Italy. The team includes President Alan L. Rivera, who sits on all portfolio company boards. Additional offices operate in Palm Beach, Florida. The Dyson Foundation functions as the family's primary philanthropic vehicle. No operational events from the last twenty-four months appear in public records. The office operates with an integrated ownership model that combines family capital, employee co-investment, and direct operational oversight. This structure eliminates external fund cycles and aligns decision-making across the Dyson family, management, and portfolio companies.
