Marion Brunken, Executive Director 
Marion, a native of Germany and a social worker by trade, has been involved in the Washington, D.C. non-profit arena for over 17 years, working with communities, nonprofit and government agencies, and volunteers. As the Executive Director, at Volunteer Alexandria, she works with local municipal and community leaders to connect needs and people to further enhance the lives of Alexandria residents, visitors and businesses. Marion has served in this role since 2012 during which time she has significantly moved the organization forward to expand programs and increase visibility in the community.

Prior to her service at Volunteer Alexandria, Marion served for eight years as the Employee Engagement Manager at Freddie Mac where she created and oversaw volunteer opportunities in the Washington, D.C. metropolitan area for over 5,000 employees. During one of her Habitat for Humanity projects she created, she had the pleasure of working with President Jimmy Carter and his wife Rosalynn. In 2005, she received Freddie Mac’s Premium Achievement Award for her leadership in engaging employees in volunteering.

Marion began her career in volunteer service management as the Special Events Coordinator with the DC volunteer center, Greater DC Cares, from 1998 to 2002. She was responsible for creating service projects for 3,000 volunteers performing community service at more than 70 schools, and nonprofit and City agencies, and for creating an event for the Martin Luther King, Jr. Day of Service in 2001 involving community leaders within the City, as well as local government. During this event, she had the pleasure of working with President Bill Clinton.

She followed as Operations Manager from 2002 to 2004 at Volunteer Alexandria (then called the Alexandria Volunteer Bureau).

Marion is a graduate of Leadership Alexandria’s first class (2004) and has served as a Virginia Volunteer since 2009 for CASA (Court Appointed Special Advocates). Currently, she serves on several community committees including, the Alexandria Council for Human Service Organizations (ACHSO), Partnership for a Healthier Alexandria, the Alexandria LGBTQ+ Task Force, and the Program SubCcommitee for the Points of Light Foundation. 

In her spare time, she likes to spend time with her wife Susan, her friends, travel, ride her motorcycle, garden and read books.

 Theresa Kramer-Burgess, Social Media Coordinator

After picking up a volunteer opportunities flyer at an outdoor event, Theresa began doing social media for Volunteer Alexandria in September 2017. She thought it sounded like a good way to give back using her experience as a marketer for mission-driven organizations. More than four years later, she continues to be amazed at the positive power of social media.

Her favorite social media posts are the Volunteer Shout Outs which show the tremendous generosity of our community and the difference that one person can make. She credits her work with Volunteer Alexandria for helping her keep a healthy outlook on life, i.e., staying sane, while quarantining with her family during COVID.

A native of the DMV, Theresa puts an “r” in Washington, a “e” in Maryland, and her heart in Virginia. She enjoys Swings coffee, the Kennedy Center Millenium Stage, and fireworks, especially at the Alexandria Birthday Party. She lives with her husband, daughter, and a cat who likes to help with the social media posts.

Theresa donates 90% of her time to Volunteer Alexandria and we couldn't do what we do without her commitment, energy, skills, talents, and time she spends with us.
