He has been a lead coordinator for numerous watershed surveys and regularly works with municipal planning boards and staff to review large and small projects. He has coordinated GPS photo inventories of many of the nearby lakes and created the official shoreland zoning maps for six surrounding towns.

Mary Jewett, teacher/naturalist, graduated from Unity College with a bachelor’s degree in science ecology in 2006. Mary’s early career at LEA began in high school when she volunteered to help with the water testing program during one summer. Since then, her volunteer work has led her to focus on diverse environmental topics. Mary worked for a summer at Avian Haven in Freedom, Maine where she helped in the rehabilitation of wild birds. She also completed a prior term of AmeriCorps service in Cherokee, North Carolina where she used field research to determine the fire risk on the Cherokee reservation. Mary has a passion for education and believes that her own feelings about the natural world inspire others to care about it too.

Alanna headshotAlanna Doughty, educator, received her Bachelor’s degree in Ecology and Environmental Science in 2005 from the University of Maine in Orono after attending Alaska Pacific University and College of the Atlantic.  Years later when she realized she was taking books out of the library simply to take notes on them, she decided to return to school at USM for a Masters in Education and finished in 2011, just shy of her daughter’s second birthday.  She cannot remember this time of her life due to sleep deprivation. She also spent time in there working for Outward Bound, Ocean Classroom, Winter Journeys, and loves being outside.  She graduated from the Lake Region School District and is excited to inspire students in learning about our local ecology. She brings her enthusiasm for the outdoors in general, and wetland plants in particular, to the table and loves being a part of the education crew at LEA.

Their three children have since become enchanted with Pleasant Mountain and the shores of Long Lake. Wells graduated from Middlebury College and Hahnemann Medical College.
