WISCASSET — Chewonki, an environmental education organization based in Wiscasset, recently announced the addition of two new staff members to lead its Outdoor Classroom and Wilderness Trip programs.

Chewonki’s Outdoor Classroom program offers day, overnight and wilderness trip programs for school groups from across Maine and New England.

Lisa Packard joins Chewonki’s Outdoor Classroom from a permaculture farm and education center in Brooks, Maine, where she was executive director. Previously, Packard spent six years at the Highlands Center for Natural History in Prescott, Ariz., where she worked closely with public school administrators and teachers to develop an award-winning outdoor science program for thousands of students at six participating public schools.

Packard has taught science, languages, and environmental subjects at Prescott College, Skyview School in Prescott, and Southern Regional High School in Manahwkin, N.J. She completed her undergraduate degree at UC Davis and a master’s in environmental education at Prescott College.

“We are thrilled to have Lisa join us at Chewonki,” said Willard Morgan, Chewonki’s president. “Lisa brings deep experience in environmental education for school groups. Furthermore, she has specific expertise with the teaching of natural history in a manner that dovetails well with the rapidly changing world of the Common Core and STEM initiatives in public education.”

Emma Mabel Carlson of Wiscasset joins Chewonki’s Wilderness Trip program from St. Lawrence University, where she was assistant director of the Adirondack Semester. Carlson is a 2008 graduate of Colby College, where she majored in and wrote an independent major titled “Environmental Education.”

Carlson worked on Chewonki’s year-round staff from 2008-11 in the Outdoor Classroom program and as a wilderness trip leader. She led Chewonki’s Maine Coast Kayak, Boat Builders Expedition and the Wilderness Leadership Expedition.

“We are particularly excited about Emma’s personal expedition experience (including a thru-paddle of the Northern Forest Canoe Trail in 2012), her experience in multiple trip elements (canoe, sea kayak, hiking and winter travel), her professional outdoor leadership training, and the genuine enthusiasm that she brings to the team,” said Greg Shute, director of Outdoor Programs, in announcing her hiring.
