MORE about Jackie

Jackie Randle’s experience with trails has spanned many years. She has been employed by the Bruce Trail Conservancy since 2002 and has been hiking her entire life.  Jackie is a strategic thinker who leads with great gratitude and appreciation for all who work hard and enjoy the trails around the world and locally on the Bruce Trail. Jackie has been fortunate to travel to many different trail locations to explore all they have to offer and hopes to continue those explorations throughout her life. During her career with the Bruce Trail Conservancy, Jackie has taken on progressively increasing amounts of responsibility in Human Resources, shaping and building an organizational culture that is based on the ideals of communication, collegiality, and collaboration. She can happily say that the Bruce Trail Conservancy is the best place that she and her co-workers have had the pleasure to work for.

Jackie’s work with the World Trails Network goes back to the very beginning. She has been very involved in the Friendship Trail program, creating connections between the Bruce Trail and nine other trails around the globe. A result of the Friendship Trail program is the opportunity for Bruce Trail volunteers to travel and give their time and skills to other trails around the globe.
