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.

Catherine Magruder, Instructor, teaches the Public Speaking series of LEAD courses.  She has been a member of Toastmasters International, District ONE for over 21 years.  She believes the benefits of learning public speaking skills builds self-confidence, improves clarity of thought, develops critiquing skills to name a few, and feels grateful to pass those benefits on.  She is the mother of two sons and one daughter, who is a past Youth Manager.  Catherine believes that youth truly are the future of the world and wants to help them accomplish their visions and goals.
