Lake Street Family Office

Lake Street Family Office

Lake Street Family Office was established in 2018 by Robert A. Goyette and Greg A. Van Slyke. The firm operates as a multi-family office offering investment and consulting services to clients. Focus Financial Partners acquired the business in 2017 ahead of the formal founding date. The firm allocates across buyout, distressed debt, growth equity, mezzanine, natural resources, secondaries and special situations. It maintains exposure to ESG mandates and holds a position in Grayscale Bitcoin Mini Trust. Geographic reach centers on Europe with additional activity in the United States. No specific co-investors or fund commitments appear in available records. Joseph Chase serves as Managing Partner and Buddy Webb as Chief Investment Officer. Greg A. Van Slyke retired at the end of 2024. The firm completed a merger with SCS Financial in March 2025. It maintains offices at 145 Maplewood Avenue in Portsmouth and 100 Federal Street in Boston. Lake Street belongs to the Family Office Exchange network and supports Catholic Charities New Hampshire, Life Science Cares and the New Hampshire Charitable Foundation. The structure reflects a hybrid model in which an independent multi-family office was integrated into a larger aggregator platform before a subsequent merger. This path distinguishes it from founder-led single-family offices that retain full operational independence.
