The Thrash-Haliburton Team

Public Affairs


Business Development

Regulatory Affairs



With a combination of expertise, energy, time, resources, and effective relationships, our team makes up one of the strongest government affairs firms in the state. We represent many clients with unique and complicated legislative and business needs and have been very successful in achieving our clients’ objectives. This includes the areas of legislation, budget matters, business development, procurement, and other types of requests from clients. Mo has been named “Top Independent Small Firm Lobbyist” in Georgia by James Magazine, a highly respected and the most read magazine dedicated to Georgia politics and the Capitol, and Thrash-Haliburton continues to rank as one of the top lobbying firms every year. Voting on these honors is made by legislators and fellow lobbyists.

The team looks forward to many more positive developments and a strong future together. You will find no one more driven, hard working, well connected, focused, and prepared in the industry! That is a promise!
