Barb Trader

(CEMWG Co-chair, AFL sub-group member, liaison to PAO sub-group)

Barb Trader retired to Frederick in 2016, with her husband, Mark Gregory, after a 40 year career in disability services and federal advocacy. Her masters and undergraduate degrees span two main interests – the enjoyment and preservation of wilderness areas and life satisfaction for people with significant disabilities. Barb’s environmental activism started at a young age and she was named the 1972 Youth Environmentalist of the Year by her Congressman, the Honorable Les Aspin. She’s a co-founder of the Multifaith Alliance of Climate Stewards of Frederick County, a member of the Sierra Club Catoctin Group and the Smarter Growth Alliance, and a board member of Envision Frederick County and SHIP of Frederick County (the Student Homelessness Initiative Partnership).  In 2019, Barb founded Healthy Soils Frederick, which has already achieved some legislative success toward the advancement of regenerative land management practices. Barb co-authored the Climate Emergency Resolution and was a leading advocate toward its adoption. She now serves as the Co-Chair of the Climate Emergency Mobilization Workgroup. In her spare time, Barb loves to hike, run, read, travel, play table games and have friends over for dinner and conversation.
