These guys really love what they do, and it shows!

Leadership Team

Our Leadership Team — all of whom provide guidance, support, and encouragement to the Camp Walden Staff — is composed of camp professionals whose backgrounds and experiences enable them to deal with the daily complexities of “operating” camp. Camp Walden’s leadership team meets regularly throughout the year to plan and prepare for the summer ahead. The Leadership Team is assembled in hopes that each team member can bring a unique perspective and expertise to our group.

Together, our team makes every effort to ensure that campers, families, and staff are afforded the best possible Camp Walden experience! It’s a big job to keep the Walden community happy, content, creative and allowing for lots of fun! Our Leadership Team is up to this challenge and we cannot emphasize how fortunate we feel in having these Walden personalities return summer after summer.
