Investment Team

Joel R. Mangham,  Founding Partner, Co-Chief Investment Officer

Joel has over 30 years of experience in investment management, founding Mangham Associates in 1991, with prior experience at Cambridge Associates, Gemini Consulting, Monsanto Corporation and the petroleum industry. During his tenure leading Mangham Associates, the firm evolved from offering investment consulting to fully discretionary Outsourced Chief Investment Officer (OCIO) services.

Joel is experienced working with foundation boards, trustees and investment committees to integrate the investment process into each client's mission and financial circumstances. As Co-Chief Investment Officer, he works closely with Ed to lead the firm's strategic vision and implementation of investment research, asset allocation, manager evaluation and portfolio construction for client solutions. As our Founding Partner, Joel ensures the team adheres to our Core Values and culture, putting clients' needs first, in a collaborative and collegial environment. Joel has also served as chair of the investment committee for the St. Anne's-Belfield School and as treasurer and chair of the finance committee for the Miller School of Albemarle.
