Jeff Guesman, Secretary



Jeff originally hails from Pittsburgh, Pennsylvania although his formative years were in the greater Chicago area gaining an appreciation of nature with the Boy Scouts.  His parents relocated to Maine in 1973 where his love for the outdoors was firmly established.  He enjoys camping, kayaking, snowshoeing and snowmobiling, but particularly hiking the vast network of trails through Maine’s forests to its numerous lakes and mountain peaks.  In the spring, you’ll find Jeff and his wife and family setting taps in trees around their home to make maple syrup.  He recently joined SRLT as a land steward after retiring in 2016 from the U.S. military and related contractors after 39 years combined service in aviation maintenance, aircraft manufacturing and Human Resources/Labor Relations.   Jeff and his wife, Gail, have three adult children and have called Newport home for 32+ years.

Deborah Dutton

Deb Dutton grew up in Waldo County and is currently a Unity resident.  She joined the Board of SRLT in 2009. Deb is interested in land conservation for the preservation of natural places as well as agricultural lands. “I like sitting in nature and watching it unfold around me.  It is the magic we miss if we allow ourselves to be distracted by the superficial.  If I can capture it with photography and bring awareness to the need to protect it, I can feel I have served a purpose.” Deb and her partner, Dave Smith, placed their land under conservation easement with the SRLT in 2007, keeping the land reserved for traditional activities like farming, responsibly managed forestry and recreation.  The Hills to Sea Trail, managed for public use by the Waldo County Trails Coalition, crosses the property.

Ellen Batchelder, Treasurer


Ellen is a Maine native who had plenty of access to the Maine outdoors growing up. After moving away from the state for college, graduate school, and post-doctoral research, she returned and was until recently an Associate Professor of Biology at Unity College, teaching courses in Introductory, Cell and Micro Biology.  As well as all the obvious benefits that diverse natural ecosystems have, Ellen appreciates the quietness of being in nature and hopes to help preserve that experience for others. She also enjoys being a connected part of the human community, and in addition to joining the SRLT Board in 2018,  she volunteers for several other local organizations.
