As the investment office for our clients, we strive to be an integrated partner. We design portfolios around specific goals and constraints, including risk tolerances, liquidity requirements, and strategic plans. But we also look to build a deeper foundation of trust and rapport, standing ready to collaborate on a broad range of financial and organizational matters as if we were an embedded member of the team.

The resources and expertise of a leading investment office
We proudly serve a select group of mission-driven nonprofits and long-term investors.
We aim to translate our clients’ return goals, spending needs, and risk tolerance into an appropriate portfolio structure, then leverage our extensive networks and endowment experience to source and underwrite compelling manager and investment opportunities across asset classes. We use diversified custom and commingled structures to help ensure efficiency, fairness, and alignment across our clients. Both multi-asset and asset class–specific portfolios are built using a single, rigorous investment process.3
