Colby grew up in Nolensville, Tenn., and attended public schools before graduating from Middle Tennessee State University and beginning his Nashville life at The Tennessean, where he covered crime, politics and higher education.
After five months as a missionary in Sao Paulo, Brazil, Colby returned to Nashville to become press secretary for the Tennessee Senate Democratic Caucus, where he directed successful public awareness efforts to maintain student-teacher ratios, preserve higher education access and increase benefits for military families.
During this time, Colby was elected co-chair of South Nashville Action People, a nonprofit that serves the Wedgewood-Houston neighborhood, where Colby and his wife Lindsey Harris bought a 90-year-old house in 2010. As co-chair, Colby successfully negotiated the first-ever protective noise restrictions at the Fairgrounds Speedway, oversaw the opening of a new community center, strengthened SNAP’s affordable housing arm, and grew cash holdings 500 percent. He completed these initiatives and more as part of the inaugural master's class at Lipscomb University’s Andrews Institute for Civic Leadership.
Colby runs his own public relations company, Sledge Strategies, and has more than a decade of experience in communications. He was lead consultant for the award-winning community outreach efforts for NashvilleNext, the countywide planning process for Nashville’s next 25 years. He has worked on topics ranging from after-school programming to comprehensive immigration reform, and co-chaired Wedgewood-Houston's Neighborhood Council on Affordable Living, which produced a guiding document for residents and developers regarding housing affordability, small business support and improved infrastructure.
Colby has been recognized in the Nashville Business Journal’s Power 100, and has been named as one of the Best Current Metro Councilmembers in the Nashville Scene’s Best of Nashville Readers Poll for three straight years.
Colby, Lindsey, their son Arthur and their dog Bandit live in Wedgewood-Houston, where they are committed to a diverse, welcoming District 17. They enjoy writing, organizing community events and taking in the vibrant arts and music scene led by many of their talented neighbors and friends.
