Locust Street Group was founded in 2008 and is headquartered in Washington, DC. From its base in the nation's capital, the firm built an integrated strategic communications and public affairs practice serving corporations, trade associations, and nonprofits. Its early identity centered on helping clients navigate complex public policy and reputational challenges, combining research, narrative, and engagement. Over its first decade and a half, LSG expanded its geographic footprint beyond Washington, establishing offices in Boston, Denver, Houston, Portland, Louisiana, and New York. This expansion supported a growing client base that included leading brands and organizations seeking to navigate complexity and deliver results. The firm developed practices in strategic insights, stakeholder engagement, public relations, and community marketing, and it assembled a network of media operatives, advocacy professionals, and community outreach experts across all 50 states, in every state capital, and with reach in every congressional district. LSG's public affairs work has included large-scale coalition and advocacy campaigns. In one representative engagement, the firm supported a group of leading energy, petrochemical, and industrial companies organizing a large-scale carbon capture and storage (CCS) collaboration in a major U.S. market. LSG conducted message testing to gauge attitudes toward CCS and identify effective messaging, then launched a coalition of 12 leading energy, petrochemical, and power generation companies, increased awareness and opinion of CCS among target audiences, and developed a campaign website and digital advertising that generated earned media. By its 15th year, LSG described itself as an impact agency with a mission to solve the world's biggest challenges by amplifying, measuring, and harnessing the voices of people and communities. The firm continued to emphasize values of accountability, collaboration, quality, adaptability, and integrity, and it positioned its data-driven approach as central to delivering meaningful impact for clients and the communities they serve. In 2026, as America marked its 250th anniversary, LSG introduced The 250, a network of 250 Americans from every corner of the country, each with a story worth telling. The initiative reflected the firm's longstanding focus on stakeholder engagement and community voices. LSG remains a privately held agency with a broad service portfolio spanning corporate affairs, public affairs, brand communications, crisis management, digital services, and community marketing.
