Bronwyn Mitchell 

Louisiana’s rich marshes, swamps and bayous fueled Bronwyn’s love for wetlands. After graduating with a B.S. in Environmental Management Systems, Bronwyn joined the Peace Corps and headed to Botswana to work as an environmental education specialist attached to Conservation International’s Okavango Delta Office. The Okavango Delta just happens to be the worldís largest inland delta and is designated as a Wetland of International Importance. While dodging hippos, Bronwyn managed to help create an interpretive trail system and nature center in a small education game park. When electricity and running water finally returned to Bronwyn’s life 2.5 years later, she Dallas for the South Pacific when she took the position of Territorial Wetland Specialist for American Samoa (2500 miles south southwest of HI). Bronwyn was instrumental in developing a wetland education program which included month long activities for Wetlands Month, teacher trainings, and community outreach. After achieving the perfect tan, the Pacific Ocean was traded for the Chesapeake Bay when Bronwyn took over as Director of Education for Environmental Concern Inc. where she was instrumental in creating a well-respected, quality-driven, national Wetland Education Program.
