A veteran campaign and policy analyst with more than a decade of high-level experience, Don Johnson leads SRG's extensive research and reporting efforts. In this role, Don provides clients with unmatched insights into policy debates, state and national political campaigns, and other public affairs intelligence to help inform business and legislative objectives.

Don launched his career as the Executive Director of the Republican Party of Shelby County where he recruited and trained volunteers for campaigns, helped to organize record-breaking fundraising events, dramatically grew e-mail advocacy reach, and put his organization at the forefront of emerging technology.

After leaving the Republican Party of Shelby County, Don was tapped to join the district staff of then-U.S. Representative Marsha Blackburn (TN-07), helping constituents navigate the complexities of federal agencies. He moved to Nashville in 2012 to join the Haslam Administration, climbing the ranks to become the governor's head of constituent services and community relations, a role that allowed Don to leverage his knowledge of the breadth of state agencies and services to provide referrals and support to constituents.

In 2019, Don was asked to continue leading the Constituent Services office for Governor Bill Lee, solidifying his reputation as one of the country's longest-serving constituent services directors who has been routinely called upon to give presentations and offer guidance to gubernatorial administrations in other states.
