M.D. Sass is an independent asset management firm established in 1972. The firm manages equity, fixed income, and alternative strategies for institutional and individual clients, including public funds, corporations, Taft-Hartley funds, endowments, foundations, private banks, and registered investment advisors. In addition to portfolio management, M.D. Sass partners with early-stage managers to develop new investment strategies and provides seeding for investment businesses.
