Avenir Corporation

Avenir Corporation

Avenir Corporation was founded in 1980 by Charles G. Mackall Jr. after seventeen years at NS&T Bank. Mackall initially ran the firm as a single-family office before accepting external accounts. The firm pursues concentrated equity portfolios using bottom-up analysis of long-term free cash flows. It holds positions across North America, Europe, and Asia. Investment types include direct co-investments, hedge fund allocations, and real estate. Confirmed holdings and strategies reference value-oriented names in enterprise software and healthcare services. Geographic reach extends to Africa and South America through opportunistic mandates. Avenir employs a team of eight professionals in Alexandria. James H. Rooney assumed day-to-day portfolio responsibility in May 2024 after twenty-six years at the firm. Adjacent vehicles include the Avenir Foundation and The Clifton Institute. The firm maintains membership in the CFA Society of Washington, D.C. Avenir operates with a hybrid structure that combines single-family discipline with multi-client separate accounts. This setup allows concentrated positions without external fund-raising cycles. Governance remains anchored by Mackall as chairman and Rooney as principal manager.
