Docent Volunteers Wanted!


Volunteers for the 2016 docent class for the Thielke/Glen Rock Arboretum, at 460 Doremus Avenue in Glen Rock, are now being recruited.  Docents give educational talks, and act as tour guides for both children and adults at the Arboretum. 

Whether conducting a tour for adults, or sharing educational knowledge with children’s groups, docents share their love and knowledge of this beautiful natural environment and heighten awareness and importance of the need to conserve nature with others. 

Docent applicants must be 18 or older and participate in an ongoing free training program instructed by the Arboretum Education Team.  Docents do not need a background in biology, science or teaching.  You just need a love of nature, a desire to give back and help others, and an enjoyment in being with other like-minded individuals. 

If you are interested, please contact the docent coordinator, Lucy Malka at 201-410-9620, For further information about the Arboretum and its programs, visit, or check us out on Facebook.
