Rebecca Serna, Executive Director

Rebecca Serna has served as the Atlanta Bicycle Coalition's Executive Director since late 2007. She holds a Master’s degree from Georgia State's Andrew Young School of Policy Studies in Urban Policy, specializing in Planning and Nonprofit Management. Serna got involved in bicycle advocacy through an internship with the Georgia DOT’s Bicycle and Pedestrian program, where she helped write the Bicycle and Pedestrian Safety Action Plan and monitored state projects for compliance with local bike plans. She draws on her experience as a Fulbright scholar in Bogotá, Colombia, where she studied participatory planning practices and innovative public transportation projects. 

Prior to joining ABC, Serna served as President and co-founder of Citizens for Progressive Transit, and is currently Vice-President of Georgia Bikes. Awards include Advocate of the Year from the Alliance for Biking and Walking and the Longleaf from the Georgia Conservancy.

Serna lives in the Kirkwood neighborhood of SE Atlanta with her husband and two sons, enjoys gardening, dancing, reading and baking, and eagerly anticipates the day when her bike commute is unremarkable.


Leslie Caceda, Program Manager

Leslie Caceda began volunteering with the Atlanta Bicycle Coalition while a graduate student at Georgia Tech. In May 2012, she served as the volunteer coordinator for Atlanta Streets Alive, and in August 2012, she joined ABC full-time as Program Manager. Prior to her position at ABC, Leslie served as the Senior Community Planner for STAND-UP, a think-and-act tank for working families, and spent two years as an environmental analyst for Alpha Environmental Management Corporation. In 2011, Leslie also received her master’s degree in environmental planning from Georgia Tech. 

Since her graduate student days, bicycling has been her passion--especially once she crunched the numbers and realized that biking to and from class would yield a big penny saved on parking and time. Armed with her partner in crime, a yellow pup named Poppins, Leslie can be found on her porch in Cabbagetown envisioning and planning Atlanta’s future.   



Keisa Bruce, Events Manager

An Atlanta native, Keisa Bruce brings over eight years of project management experience to the 2014 Events Manager position. Prior to joining ABC, she managed a diverse portfolio of high profile, experiential campaigns at Team Epic and Next Marketing, based in Atlanta, while traveling all over North America.

A graduate of the University of Georgia, she has been a staunch supporter of all things that create sustainability in the city and, while vowing not to rely on a car for many years upon her return, Keisa fell in love with cycling immediately. You can find her biking around Decatur and East Atlanta en route to a volunteer project or meeting to discuss innovative ways to encourage physical activity at all ages. 

Adam Nguyen, Membership Coordinator

Zahra Alabanza, Earn a Bike

Zahra is the co-founder of the Atlanta chapter of Red, Bike and Green. She has planned and completed two long distance bike tours (one of which she pulled her then 5 year old along for the ride) as a founding member of the Spoke N' Heart Collective. Zahra hails from Hawaii and California with roots in Florida and Chicago.   

Zahra rides a bike named Pearl that moves her through space and time. She sees biking as a tool for communal and individual transformation as well as a means of building and rebuilding whole communities that are abundantly safe, confident, well(thy) and self determining.
