Julia Broadbent - Educator/Counselor

Julia grew up in Upper Saddle River, NJ. When it came time for college, she knew that she wanted to accomplish something big and make an impact on the world.

While at school Julia works as a barista at a coffee shop, as well as at a small boutique. In May 2019, she joined the Weis team as an intern, and assisted with school field trips and summer camp. As someone who had babysat children of all ages while in high school, Julia was ready to jump in and work with the kids. While not initially focused on the education part of Environmental/Sustainability studies, Julia took to it quickly and it became something that she was passionate about. Throughout her internship, Julia demonstrated her initiative and leadership skills, and was promoted from an assistant to a full educator/counselor role. She returned as head counselor for our 2019 Winter Break Camp, and will rejoin the Weis team again for future nature day camps. ​

Stephen was inspired to join our team after reading about our educational programs that teach young people about the beauty of our natural environment. He believes these programs are vital for an environmentally responsible society, and feels if more youth were exposed to the natural world, then surely the next generation will cherish nature for the wonder that it is. As an Eagle Scout, he firmly believes in the principles of protecting and preserving our environment, and hopes to develop a career in property and environmental law, to help conserve our outdoor spaces. In his free time he is an avid hiker, and rears Eastern Hercules Beetles (Dynastes Tityus) which he finds fascinating.
