Mountain Hill Investment Partners

Andrew J. Kaiser established Mountain Hill Investment Partners in 2006 following a 20-year Wall Street career. His personal investment gains form the disclosed capital base. The firm operates as a privately owned SEC-registered investment advisor serving a limited roster of families, charitable organizations, corporations, and 401(k) plans. The firm allocates across public equities and hedge funds while avoiding private equity commitments. It constructs portfolios through internal fundamental research and direct trading rather than fund-of-funds vehicles or external managers. Geographic exposure centers on North America. No specific portfolio holdings or co-investors appear in public materials. The team includes three named partners who handle client relationships, trading, and 401(k) advisory. Andrew J. Kaiser serves as managing partner. Michael H. Meyers joined in 2007 and co-manages the core equity strategy. Lauren G. Siewert joined in 2019 and leads the 401(k) services group. The firm maintains one office in Atlantic Highlands, New Jersey, and supports the Ryan Andrew Kaiser Memorial Foundation through profit donations. Kaiser personally oversees all client relationships and maintains direct trading-desk access without layers of internal meetings. This structure keeps decision-making concentrated with the founder rather than delegated to separate investment committees or external sub-advisors.
