Executive Staff

The Capital Metro Executive Staff is comprised of leaders in operations and planning, safety, customer experience and diversity and inclusion. Read about the members of our leadership team below. 


President and CEO - Prior to joining Capital Metro, Randy Clarke held key leadership positions in public transportation in both Boston and Washington, D.C., and earned a master's degree in public policy from the University of Southern Maine.

Since he joined Capital Metro and following the 2018 redesign of its bus network, transit ridership has been on the rise in the Austin area. Clarke sees the operation through the eyes of his customer by using the service every day, giving him insight that's fueled his challenge to “do more” in providing quality transportation options to the growing region. That familiarity with the service led Clarke to put in place multimillion dollar investments to the system and a renewed focus on improving customer experience
