Our Staff

Gail Church, Executive Director, was present for the founding of TREE MUSKETEERS, and left an airline management career to become its CEO. Years of volunteer service to youth and graduate studies in nonprofit organizational management allow her to skillfully mentor youth leaders. Due to a small staff running a large organization, Gail’s Executive Director duties include development and program direction. Under her leadership, the group grew from local tree planting project to an international scope.
