Liz Appel

Elizabeth Appel
As an attorney, I recognize that laws are a necessary backbone of environmental protection, but I strongly believe that community-based initiatives are the key to proactively facing all types of environmental challenges—ranging from litter, to expanding landfills, to global warming. Since its establishment more than 36 years ago as a litter control agency, ACE has grown to help the Arlington community confront new challenges and promote sustainable living. I’m honored to have the opportunity to share both my urban planning and environmental law expertise to help ACE continue on this mission and make Arlington a model in sustainable communities.

Alex Brown

—As a student at Washington-Lee high school, I understand that my generation will soon inherit the world and its challenges. We need to start solving problems before it is too late, and the environment is one of the most important issues we face. I want to support the community and at the same time make a difference globally. I have volunteered for the Energy Masters and the Rain Barrel Programs with ACE, and I have found these experiences to be rewarding. My goal as a board member of ACE is to raise awareness of environmental issues among students and to help the environment.


Stephanie CliffordStephanie Dix Clifford
As ACE continues to expand our outreach and services and raise our profile in the community,  I am looking forward to having the opportunity to continue my role in the organization. I’ll use my background in environmental technology, community organizing, non-profit management, and communications to build our internal organizational strength and capacity to effectively serve the community. Working with the rest of our team, we will make ACE a go-to source for information on sustainable living and expand our outreach to those who are not typical environmentalists. We will reach out to more renters, homeowners, and businesses who could benefit from the services ACE specializes in. ACE will continue to grow and play a major role in larger community conversations and strategic plans on the future of Arlington as a model sustainable community

Bess Foley

—I have been an environmentalist since exploring the woods near my childhood home, and as a college student reading and taking to heart Buckminster Fuller’s description of our planet as the irreplaceable “spaceship earth.” As a resident of Arlington since the late 70s, and a long time member and supporter of ACE, I am honored to bring to the board my experience in nonprofit management and communications to promote ACE and its mission goals. To support ACE’s growth and impact, I hope that at least one person in each Arlington household will become a member of ACE.

Rick KellerRick Keller
My environmental awareness began in 1970 at a sparsely attended Earth Day event in State College, PA. Over the years I volunteered at various environmental events and contributed to organizations doing environmental work, but it was not until I retired from the Federal Government at the end of 2004 that I became a true activist. I was looking for something to do that had meaning and would benefit the future of my (now adult) children. I realized that for me the solution lay with environmental stewardship. It seems trite to say we only have one world so we better take care of it. Yet there are so many powerful voices that try and convince us otherwise. Through ACE I hope to continue to work toward overcoming those voices and support Arlington’s efforts to make this a sustainable place to live for future generations.

Don Masters
As a young resident of Arlington in the 1980’s, I watched the building of I-66 as it came through the neighborhood, bringing with it a multitude of changes. From those early days I have been involved continuously in the Arlington community through my community association, stream clean-ups, invasive plant removal actions, Christmas in April events, the reconstruction of the Reed School and Westover Library, and the East Falls Church redesign planning effort. I am honored to be a board member of ACE where I can continue to make a difference in the environmental quality of Arlington life for all its residents.  I have a great respect for the environment and will use my talents in support of ACE’s goal to provide a sustainable community that will be a shining example for other communities to follow. My interest is in bringing the environmental efficiencies and choices that are now being heavily implemented by businesses and real estate developers to all Arlington residents in ways that are cost effective and convenient to implement.

Joan McIntyre

—I am deeply concerned about the growing impact of climate change and general environment degradation and am convinced that grassroots actions are an important part of the solution.  ACE plays a key role in supporting community action to make Arlington more environmentally sustainable.  I have volunteered for ACE for the last few years and as I enter retirement from the federal government, I look forward to using my organizational and planning skills to assist ACE in furthering its mission.   I plan also to become a Master Gardener and blend my interest in sustainable landscaping with my work with ACE.

Mike MurthaMichael Murtha
I have a vested interest in preserving Arlington’s environment as a resident of the county since 1945, a past chair of the Arlington Planning Commission and a current member of the county’s Environment and Energy Conservation Commission, and through my efforts as a co-chair of the Task Force on the Physical Environment for the Commission on Arlington’s Future, a member of the Task Force on Arlington’s Future: A Vison for the 21st Century, and co-founder of the Arlington Community Sustainability Roundtable. In addition, I have parallel professional interests as vice president and co-founder of the Community Sustainability Resource Institute and my past work with the National Institute of Building Sciences, the National Building Museum, and the Association for the Study of Man-Environment Relations. I am currently working on a book, tentatively titled “Sidewalks Are For People: How Your Neighborhood Can Become a Sustainable Village,” which contains many of the elements of ACE’s Green Living Challenge.

Linh OngLinh Ong
“Think Globally, Act Locally” is where it all starts. Arlington is my home and I believe that protecting and preserving this awesome community and its natural environment must have priority. When I established my sign and graphics company Pure Media Sign Studio, I learned not only to offer my clients greener alternatives but found the greater impact to be in educating other businesses in the sign industry about how to grow a greener clientele. As a member of the Board, I would focus on working with Arlington’s business community to be more involved in traveling on ACE’s path towards a clean and sustainable community.

Julie Scarengella

—As an Arlington resident who works in the environmental industry, I am excited to bring my knowledge, skills, and passion for the environment to support ACE’s mission and my local community.   As a recent graduate of the 2013-2014 Energy Master’s Program, a member of the ACE Board and Development Committee, and a participant on the Energy Masters and ACE Communication Task Forces I have had the opportunity to engage with ACE.  As part of the ACE Board I bring my communication and outreach experience, specifically within the environmental domain, to ACE to help guide us in innovative and powerful ways.

Thomas Sheldon

—I’m so pleased to be a part of ACE, the only organization of its kind in Arlington focusing on local action to keep our streams clean, enhance our urban tree canopy, make affordable housing in Arlington more energy and water efficient, and educate citizens about sustainable living.  ACE offers so many programs and opportunities for environmentally conscious, civic-minded Arlingtonians– come volunteer at an ACE event to learn more about us!

Patrick TallaricoPatrick Tallarico
I have been working in the environmental field for my entire career – over 25 years. I have been fortunate to be part of the evolution of the environmental field from an early focus on regulations to the more recent emphasis on long-term sustainability. I now spend my career helping bring individuals and organizations together in productive dialogue to solve their environmental, organizational, and programmatic challenges.  I moved to Arlington in 1998 – at the beginning of a redevelopment boom that continues today. Growth across the County has meant increases in amenities, but it has also put obvious stresses on our infrastructure and environment. I joined the ACE Board because ACE fills the gap in environmental protection between federal, state, and local programs and on-the-ground results. Its focus on mobilizing citizens to action is key to keeping Arlington clean and helping preserve our local environment for future generations.

Helen Turvene

—I am a student at Washington-Lee High School and have been in the Arlington Public School system all my life. My interest in environmental issues goes back to being a recycling ranger at Long Branch Elementary School. I recently became an ACE Energy Master. In this program, I have appreciated learning new energy conservation techniques and interacting with the tenants. When I graduate I plan to study environmental science or environmental engineering.

Elizabeth Woolford

—Ever since I was little, nature and the great outdoors have been an important part of my life. My family and Girl Scout troop emphasize the outdoors, and the threat our urban community places on the environment. I am currently pursuing a Girl Scout Gold Award project centered on green roofs and the positive impact they have. As a lifelong Arlingtonian, and someone who makes preserving the environment a priority, I have experienced the positive impact ACE has in Arlington. As a Board Member, I am excited to find ways to broaden ACE’s youth participation, and provide a unique student perspective that can contribute to its programs and decisions.
