Sharon Feigon
Executive Director


Sharon is a founder and the executive director of the Shared-Use Mobility Center, a non-profit public-interest organization working to foster collaboration in shared mobility and help connect the growing industry with transit agencies, cities and communities across the nation. As executive director, Sharon leads SUMC’s work, which includes conducting innovative research around the impacts of shared mobility, developing pilot projects to test shared mobility strategies, and providing advice and technical assistance to cities and regions in order to help extend the benefits of shared mobility for all. SUMC was also recently awarded a contract to develop the Innovation Knowledge Accelerator in partnership with the Federal Transit Administration to assist cities undertaking Mobility on Demand projects.

Sharon was previously the CEO of IGO Carsharing, the nonprofit organization that started carsharing in the Chicago region. Under Sharon’s leadership, IGO grew from a small pilot project into a successful operating company with 15,000 members in 45 neighborhoods. Sharon worked with the Chicago Transit Authority to create the only combined car-share/transit fare card in North America, which continues to serve as a model for the possibilities between shared-use companies and public transit. She led IGO’s expansion into underserved communities and also developed solar canopies and charging stations that helped introduce renewable charging and mobility hubs to the region.

Prior to taking the helm at IGO, Sharon was the Director of Research & Development at the Center for Neighborhood Technology for more than a decade. She was the Principal Investigator for Combating Global Warming Through Sustainable Surface Transportation and was the lead author of TCRP Report 93: Travel Matters: Mitigating Climate Change with Sustainable Surface Transportation. Before that, Sharon coordinated CNT’s Transit-Oriented Development Program and was one of the authors of The New Transit Town.

Sharon was a founder of the national Carsharing Association and has served as Co-Chair of the Transportation Research Board’s Shared Vehicle Committee and as a member of the U.S. Green Building Council’s LEED-ND Committee, which created LEED standards for neighborhood developments. She holds an MBA from DePaul University and a BA in Economics from Antioch College.

Creighton Randall
Program and Development Director


Creighton leads SUMC’s work with cities to develop pilot programs, funding and policy environments for shared-use mobility so that these systems can work better for everyone.

As the former Executive Director and Co-Founder of Buffalo CarShare, Creighton helped to grow the program from an idea to a successful non-profit organization providing carsharing and bikesharing services to over 1,000 members. Buffalo Carshare–acquired by Zipcar in 2015–led the industry in serving a diverse population, and the organization was also the first in North America to launch and maintain a flexible bikeshare network (now Reddy Bikeshare).

In addition to pilot program work at SUMC, Creighton advises regional transportation leaders on shared mobility policy and programs. These efforts are currently concentrated in Los Angeles, the Twin Cities, and Upstate New York. Creighton holds a B.S. in Mechanical Engineering and a Masters in Urban Planning from the University at Buffalo.
