Our Story

Third Sector Company has been a national pioneer in the study and advancement of strategic transitional leadership for nonprofit organizations with service to over 800 organizations, professional and trade associations as well as training and support to over 200 independent interim executives.

Starting in 2002, a group of about 40 nonprofit executives from leading organizations, both large and small, from throughout the Greater Los Angeles area gathered to talk about the growing amount of turnover occurring among their peers. At the same time, the funding community was realizing the nonprofit sector was ill-prepared for executive transitions complicated by few nonprofit organizations having directed activities aimed at succession planning, executive retention, and talent pipelines cultivating future staff and board leaders.

With a mission statement of “leadership continuity for the nonprofit sector,” the group formed a professional community, under the leadership of Jeffrey R. Wilcox, President & Chief Engagement Officer. Now serving the United States and Canada through online training programs, virtual community groups, and on-demand online consultations having helped over 700 nonprofits in two nations, Third Sector Company stands committed to further evolve its founding principals in unique and impactful ways that lift the nonprofit sector to higher ground in its service to others.
