board of directors

Atiba Mbiwan joined the ABC Board of Directors in 2008 after being a member and supporter for many years. His love for cycling began in 1970 when he started delivering newspapers on a bike in his hometown of Jamaica, Queens. For the past 14 years, “Coach Atiba” has led the Bike Ride Across Georgia Dream Team in the annual trek across the state, helping more than 125 middle school youth complete the ride with the assistance of adult mentors.

Atiba serves as the Associate Director of The Zeist Foundation, a family foundation based in Atlanta that supports nonprofits serving children and youth in the areas of Education, Arts & Culture and Health & Human Services. Prior to joining The Zeist Foundation, Atiba served as the Program Officer responsible for education grantmaking at the Arthur M. Blank Family Foundation from 2001-2005.

Dr. Jim Sandlin is a native of Atlanta, growing up in Clayton County. He's ridden his bike since childhood as a source of transportation and recreation. Jim helped form the Gwinnett Bicycle Users Group, BikeGwinnett, in 1997, and has since worked with the Gwinnett DOT in developing a comprehensive policy for bicycle accommodation. Jim also facilitated ABC's participation in Safe Routes to School as we developed the statewide program for the Georgia DOT.

Jim is currently a general dentist in Lawrenceville, and lives with his wife and children in Duluth. He often commutes to his office and volunteers for ABC as a League of American Cyclists certified League Cycling Instructor. Jim also enjoys working with Boy Scouts and combines his love of bicycling with a love of the outdoors during frequent self-contained tours.

Liz Wattenberg joined Zipcar (formerly Flexcar) in May of 2006 as General Manager for the Atlanta market. She brought with her a wide range of experience in marketing and sales, as well as business administration. Having always enjoyed working in a capacity to make a difference, for the four years prior, Liz promoted alternative commuting, as program manager of the Perimeter Transportation Coalition.

Liz continues to work closely with many community partners, such at the Atlanta Bicycle Campaign, to help make car-sharing a viable transportation option in Atlanta. In addition, as a League of American Cyclists certified League Cycling Instructor, she has taught a number of of our Confident City Cycling classes.

Rachael Spiewak directs Sopo Bicycle Cooperative, Atlanta's nonprofit community bicycle repair shop.

Rachael came to Atlanta in 1999 to pursue an education in cultural anthropology at Emory University. Assigned to study a local sustainable development project, she found herself as a researcher, and later, a volunteer and board member of Decatur Yellow Bikes. As the only volunteer without a bicycle, she was given Adopt-A-Bike number 10 (which appeared to be a 1970s Fuji Mixte). Later, she was awarded a University grant to research community bicycle programing in Copenhagen, Denmark.

After graduating from Emory, Rachael worked briefly as the Girls Bike Club Leader for the Atlanta Bicycle Campaign. She returned to school to pursue a master of social work degree at Georgia State University. During her graduate studies, she and her friends founded Sopo, which is where you can find her and get a little help with your bicycle repairs every Tuesday and Thursday night and Saturday and Sunday afternoon.
