Briar Hall Management LLC is an investment management firm headquartered in Chicago, Illinois. The firm manages several billion in assets and primarily serves as an investment office for the Crown family, a prominent Chicago-based family. It has a minimal staff—typical of single family offices or dedicated investment entities—and manages the family's multi-generational wealth mainly through large, concentrated equity positions. Founded around 2017 or earlier, the firm primarily invests and oversees holdings in public securities.

This conservative, highly concentrated, and generational wealth management approach prioritizes capital preservation and steady growth through core equity holdings.
