Tallwoods Partners

Tallwoods Partners was established in 2013 by Michael Resnick, who previously led the alternatives group at William Harris Investors from 2000 to 2013. The multi-family office was created to manage capital for multiple high-net-worth families alongside the principals’ own wealth. It maintains an independent structure that coordinates investment management with tax, legal, and estate advisory. The firm allocates across public equities, hedge funds, private equity, real estate, infrastructure, private credit, and commodities. It commits through fund investments, co-investments, and direct deals while seeding select alternative managers. Confirmed positions include the Long Island Smart Growth Project and the Syracuse Urban Partnership mixed-use development in New York. Geographic exposure centers on North America with additional commodity and infrastructure holdings. The team consists of three named principals and strategic partners. Michael Resnick serves as Co-Founder and Managing Director. Bennett Lavin acts as Director after investment banking experience at Baird. Stephen Siderow participates as Strategic Partner and previously co-founded BlueMountain Capital Management. No additional offices are disclosed. Michael Resnick sits on the Invest for Kids Advisory Board. Tallwoods maintains alignment by investing its principals’ capital alongside clients rather than relying on asset-gathering fees. This structure shapes mandate selection and manager relationships. The firm also participates in the Invest for Kids philanthropic network through Resnick’s advisory role.
