Green Ambassadors

Dream Green

Cathleen Stone Island Outward Bound’s Green Ambassador Program offers Boston high school students paid summer employment in the green job sector. Green Ambassadors is a three-year program combining paid employment and structured outdoor learning. Green Ambassadors work for six weeks on Cathleen Stone Island, performing much of the work needed to maintain and preserve the trails and ecosystems of Cathleen Stone Island and other Harbor Islands.

Green Ambassadors gain hands-on experience in natural resource management and environmental conservation, engage in carpentry and citizen science, learn about climate change and environmental justice, and explore career opportunities in the green jobs sector.


Green Ambassadors are required to complete the following activities during their employment:

  • Work outdoors in all weather conditions with six to nine other employees
  • Practice trail maintenance, habitat preservation and invasive species removal
  • Perform scientific monitoring and data collection
  • Participate in at least one multi-night camping expedition in the Harbor Islands
  • Interact with marine scientists, educators, National Park staff and other natural resource departments in the Boston Harbor
  • Learn about urban agriculture
  • Engage in community outreach projects
  • Explore career opportunities within the Harbor Islands and green industries


Applicants must be residents of the City of Boston, be 15-18 years of age, possess an interest in working outdoors, developing leadership skills and learning about environmental stewardship. They must also demonstrate a strong work ethic and a commitment to complete the entire program. Preference is given to Boston Public School students.

J'Saun Bastien

“I always tell people, I’m not good with names, but I remember everyone I met in Green Ambassadors because it was a family. It was just that special. Even when we didn’t agree, we could always find a way to work together. The program really helped me a lot in developing as a person and becoming who I am today.”

JSaun was a GA from 2014-2016, after which he studied environmental science at Boston College. After graduating college in 2020 he came back to Cathleen Stone Island as a full-time Course Director, where he helped shape the experience of future Green Ambassadors. While J’Saun is no longer directly involved in the program, he encourages anyone considering the program to apply, because he believes that everyone can learn something from being a GA.
