Green Leader Brigade


​​Go Beyond Your Own Backyard

​​A special initiative of the Frederick County Office of Sustainability and Environmental Resources (OSER), it is a “go-to” group of volunteers, ages 16 and above, who help with yearly stream cleanups, tree plantings, and other environmental projects. ​

Become a Volunteer

As a Green Leader Brigade volunteer, you can participate in events,  receive trainings on various topics, and learn how to organize your own events. However, training workshop attendance is not a prerequisite to participate as a Green Leader Brigade volunteer.

Skill-building sessions and hands-on projects will provide Green Leader Brigade volunteers with the knowledge and experience needed to assist local organizations with environmental projects, as well as identify projects that can be done in their own communities. OSER can also work with you to help organize your event, generate volunteers, and provide materials such as storm drain stenciling kits.
