Who We Are

Ambler EAC members initiate and sustain projects that improve Ambler’s ecological assets.  We also build awareness of environmental issues in the region.  We write proposals to obtain funding for projects and work with the Borough to fulfill grants when awarded.

Borough Council appoints residents who apply to serve a 3 year term as EAC Members.  Associate members, who are not appointed and may not live within borough limits, volunteer to help with these initiatives.

Matt has a B.A. in Political Science from Temple University, and an M.A. in Professional Communication from La Salle. Matt and his family have made a conscious decision to be as environmentally responsible as their budget will permit. They have solar panels on their roof; they drive a hybrid car; they compost, and they have a rain barrel; and their home is almost completely outfitted with energy-efficient, LED lighting. Matt does not enjoy referring to himself in the third person.

Mary Margaret MonserMary-Margaret Monser

Mary-Margaret’s interest in the outdoors and environment was instilled from a young age having spent summers in upstate New York with relatives who imparted a love and joy of the outdoors and being environmentally conscious. As a Girl Scout leader, with three daughters, she led an active troop that spent a lot time doing “outdoor things” at Ambler Borough Park,  volunteering for Plant Ambler, participating in Earth Day and WVWA creek clean up activities, among other things. Being a part of the EAC is a natural fit that allows stewardship in the community and environment we live in. As well, she has been a resident of Ambler Borough since 1980 and currently works in the healthcare industry.
