About

I’m a public policy, communications and external affairs executive with more than two decades of experience working on technology, digital infrastructure, energy and government. I’m now Vice President of Policy and External Affairs at Cologix, one of North America’s leading data center and interconnection providers, where I lead government relations, stakeholder engagement and external affairs strategy across key markets and growth regions.

Before Cologix, I led U.S. Policy Communications at Amazon, shaping national and hyperlocal communications on data center infrastructure, artificial intelligence, cybersecurity, energy policy and economic development, at the federal, state and local level.

Earlier I founded Stonewall Strategies and served as Executive Director of TechSC, South Carolina’s first statewide technology industry association. Before that came more than a decade on Capitol Hill, as Communications Director to Rep. Mike Turner and senior advisor to Rep. Joe Wilson.

Technology has always been home base. I started writing programs in the third grade, hold CompTIA A+ and Network+ certifications, and today build iOS apps in Swift alongside my policy work. Two of them are live on the App Store, DC Metro and College Football 2026, with more in the pipeline.
