Liz AppelElizabeth 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.

Amni BibiAmna Bibi
Although I’ve been a longtime environmentalist, it was only until I worked on energy efficiency and water conservation projects as a college student, and began to quantify the energy and cost savings of these projects, that I realized the impact that hands-on, grassroots efforts can make. I’ve since found that ACE uses these same principles as its foundation, and even as environmental concerns have grown since ACE’s founding in 1978 and our responsibility to address these concerns has increased, there is an equally great opportunity to make a difference in the local community. To meet this ever-growing need, ACE will continue to be the leading organization in Arlington not only for those who are not entirely convinced of the urgency of environmental issues, but also for those who are and are looking for practical ways to become part of the solution. I’m always inspired by the passion and dedication of our staff and volunteers and am looking forward to helping build on ACE’s progress and expand ACE’s reach.

Alex BrownAlex 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 FoleyBess 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.


Al LarsenAl Larsen
I have been an attorney in private practice, in the areas of energy, environment and natural resources, concentrating on renewable energy resources. I left private practice to be a senior officer of a wind energy company. Now I am in the federal government, with EPA. So, I have seen energy and environmental policy from the private side and the government side, from creating policy to implementing policy. What draws me to ACE is that, while policy, laws and regulations are needed to protect our environment, making policy and legal changes can take a long time, and relies on bringing others along before those changes can happen. ACE is doing things now, things that anyone can choose to do, without waiting for a new statute to pass, or new rules to go into effect. If someone wants to clean up a river shore, or recycle their waste, or use sustainable building materials, or reduce energy use or…well, the point is that there are many, many choices we can make right now, without new laws, by ourselves without having to convince anyone else–and ACE is showing people what those choices are and how to exercise them. Here, and now, not pie in the sky in the future.

Don MastersDon 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 McIntyreJoan 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.

Sarah MenonSarah Menon
Serving as a Virginia Master Naturalist in Arlington for several years, I’ve studied the ecosystems that comprise our local environment and volunteered on projects to address some of the threats to those systems. At the same time, I’ve spent several years directing and/or serving as a Board member for a local science- and nature-based summer camp that focuses in part on cultivating a love of natural spaces in the next generation. I’m excited to bring my experiences working to enhance Arlington’s natural environment and managing nonprofit Boards to help further ACE’s strategic and operation goals.


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.

Joshua RichardsJoshua Richards
Coming of age in Northern Virginia, I witnessed firsthand both the many wonders of the natural world and the rapid development of this area ‘“ from pastures and small city centers to shopping malls, vineyards, and more single-family housing than you can shake a stick at! But with great development comes great responsibility. As a professional in the sustainability industry, I firmly believe in the power of the triple bottom line–people, planet, profit. By balancing these three elements across the suite of actions we take, I remain wildly optimistic at the potential for human innovation to address and correct the growing threats of climate change and environmental degradation. It is a true honor to be selected to serve the Greater Arlington community as a board member with ACE, and I look forward to helping advance some of the great programs and initiatives that will change this community for the better and ensure a healthy, productive future for my family and yours.

Carol RitzCarol Ritz
Over my two decades in Arlington, my concern for the environment has evolved from an interest to a passion. My husband and I joined ACE, which spurred us to experiment with vermiculture, install solar panels and a rain barrel, telecommute and/or bike to work, and purchase hybrid/fuel efficient cars as well as an energy efficient furnace and energy star appliances. Most recently, I’ve become certified in a sustainable food production system, permaculture, through George Mason University. When I started following environmental issues, the primary hurdle was awareness. Now, the key to success is motivating concerned citizens to action, and local organizations like ACE will be at the forefront. I’m honored and excited to devote my energy and skills as an author and filmmaker, as well as an attorney and financial professional to that effort.

Thomas SheldonThomas 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!


Helen TurveneHelen 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 WoolfordElizabeth 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.
