Brandon Beach holds an undergraduate degree from Centenary College and a Master of Business Administration. He has held positions on the Alpharetta City Council and the Alpharetta Planning and Zoning Commission. Beach spent six years in the Georgia Senate, where he chaired the Transportation committee and served on multiple other committees. He has demonstrated leadership in both the private and public sectors, transitioning from managing institutional risk in high-finance to significant roles in state government.

Brandon Beach's political identity is marked by a blend of ideological rigidity and surprising policy alliances. He co-sponsored legislation to defund libraries affiliated with the American Library Association, yet his actions during the COVID-19 pandemic reveal a disregard for public health protocols. Beach's support for overturning the 2020 presidential election in Georgia, despite baseless fraud claims, demonstrates a commitment to election integrity that borders on the extreme. His endorsement of President Trump's signature on U.S. currency further highlights a distinctive alignment with controversial figures.
