Who We Are


Gabriela Arismendi

Gabriela Arismendi has been a member of the Working Bikes Board of Directors since December 2009. She currently works for the Chicago Public Schools and has a background in nonprofit management. Gabriela holds a Master’s degree from the University of Chicago School of Social Service Administration and a Bachelor’s in Secondary English Education from the University of Illinois at Chicago. She came to Working Bikes because of her interest in international aid and loves knowing that the work done from the warehouse in Chicago has an impact in communities across the globe. Gabriela was born and raised in Chicago but enjoys travelling and getting to bike in new places outside of the city.


Trevor Clarke

Trevor Clarke is the Secretary of Working Bikes.  He is a practicing attorney and often the only person in The Law Office of Trevor J. Clarke.  In addition to handling some of the organization’s legal issues, Trevor volunteers his non-professional mechanic skills, coordinates events, keeps the corporate records, and helps develop community programming. Trevor was introduced to Working Bikes during a stint interning in the Office of General Counsel at the MacArthur Foundation in 2011. He is an inaugural member of the Justice Entrepreneurs Project, a social justice minded law firm incubator, which has helped him build a practice focused on the needs of nonprofits and small businesses. He spent some time as an attorney in residence at The Law Project helping strengthen community organizations, both for- and non- profit, by providing pro bono transactional legal services.  Before becoming an attorney, Trevor held a slew of jobs. Some allowed him to play with fancy microscopes.  One gave him a great excuse to bike commute in Japan.


Amelia Jaffe

Amelia Jaffe has been a Working Bikes volunteer for over three years. After spending two years in Central America learning about sustainable building and living practices, Amelia came to Working Bikes to continue her involvement in international relief, sustainable transportation, and building and repair. Although Amelia began primarily as a volunteer mechanic, she is increasingly active in organizing Working Bikes volunteers and events. She is just beginning her career as an emergency room nurse, having recently completed a Master’s degree in nursing at Rush University. Amelia also holds a Bachelor’s degree from the University of Wisconsin – Madison in Spanish and Psychology, and worked previously in social work for non-profit mental health clinics.


Phil Kaplan 

Phil Kaplan is Vice-President of the Board and chair of the Staffing Committee. He worked for the U.S. Environmental Protection Agency for over 30 years, focusing on waste reduction. Phil first volunteered for Working Bikes in 2008 for a “shipping party” to Tanzania, which he had visited the previous year. He then began to work on events and bike repair, eventually becoming involved in all aspects of Working Bikes’ operations. Phil is particularly keen on increasing the quantity and quality of bikes donated over the upcoming years. When not volunteering his time at Working Bikes, he is an avid cross country skier and biker.


Jim Lindsey

Jim is a financial executive with TTX Company. He leads the company’s assurance function and advises management and the Board of Directors on matters of risk, control and governance. Prior to joining TTX, he was with the public accounting firm of Arthur Andersen. Jim has an MBA from the University of Chicago Graduate (Booth) School of Business and has been a CPA since 1984. He is a member of the American Institute of CPAs and served on the Accounting Principles Committee of the Illinois CPA Society for over ten years. Jim has served on various not-for-profit boards, is a volunteer with CPAs for the Public Interest and was a Grant Review Panelist for the City Arts Program of the Department of Cultural Affairs, City of Chicago. Jim became involved with Working Bikes through his daughter, who conducted bike drives in the Beverly neighborhood of Chicago during her high school years. After she went off to college, Jim learned that Working Bikes was looking for accounting assistance–and the rest is history. Jim is concentrating on implementing an accounting system, among other things, in order to produce high-quality financial information on a regular basis for decision-making and control.


Amy Little

Amy Little has been a volunteer at Working Bikes since its inception, and a board member for 6 years. She manages real estate for a living, while volunteering for groups with an environmental bent, including the League of Women Voters and Working Bikes. Amy has a BA in Economics from Wellesley College, and an MBA from Kellogg School of Management, Northwestern. She also spent two years in the US Peace Corps in Guatemala, and is fluent in Spanish. Amy is married to Lee Ravenscroft and the mother of one son, Magnus, who studies Engineering at Purdue.


Lee Ravenscroft

Working Bikes founder and Board President Lee Ravenscroft holds degrees in Elementary Education from the University of Wisconsin and Electrical Engineering from the University of Illinois (a Quadruple E Degree, you could say). As an engineer, Lee worked for Rockwell International, Contemporary Control Systems, and Commonwealth Edison. In the non-profit sector he worked with Tecnica and the Nicaragua Solidarity Committee. Lee was motivated to start Working Bikes in 1999, after he spotted a truck loaded with bikes on its way to the dump. He followed the truck and collected the bikes, returning most Mondays for the next five years. Looking to the work of Bikes Not Bombs, Pastors for Peace, and the American Friends Service Committee, Lee’s bike salvaging evolved into the organization that would become Working Bikes.


Pete Travnicek

Pete Travnicek is the Treasurer of Working Bikes. He joined the organization as a volunteer in the fall of 2009, following the pursuit of a used bike seat for his road bike, and has been a board member since 2010. Pete spent 8 years on Wall Street prior to obtaining his MBA at The University of Notre Dame and currently works in financial software sales. His goal within Working Bikes is to expand the organization’s footprint via sound and transparent financial decision making. Pete lives with his wife and two children in the East Ukranian Village neighborhood of Chicago.


Eric Wood

Eric Wood has been a volunteer at Working Bikes since 2003 and has helped grow the organization through his work with bike drives, acting as a community bike drop location in suburban Elmhurst, and serving as a board member for the past five years. Eric graduated from the University of Tennessee with a BA in Economics and has been in the IT industry for the past 27 years. He was attracted to Working Bikes by their international mission and their focus on rescuing bicycles before they become trash. Eric is an avid cyclist and self-taught bike mechanic.
