Florida’s The Southern Group Rapidly Scales Washington Presence Under Trump-Era Opportunity
New federal arm TSG Advocates DC signs major clients and posts strong growth amid shifting U.S. investment climate
Florida-based government-relations firm The Southern Group has swiftly expanded into Washington, D.C., launching its federal lobbying arm, TSG Advocates DC, in January 2025 and claiming rapid growth and major mandates in its early months.
The firm says it signed dozens of clients—including major names such as American Airlines Group Inc., Volkswagen and Axon Enterprise Inc.—as it capitalises on what it sees as a “new, business-friendly era” under the administration of President Donald J. Trump.
TSG Advocates DC’s growth is reflected in publicly-disclosed filings: OpenSecrets reports the firm reported roughly US$1.46 million in federal-lobbying spending so far this year through 2025. Its Florida parent describes third-quarter revenues as having surged by nearly 450 per cent compared with the first quarter, though full figures remain tight.
The expansion builds on The Southern Group’s more than two decades operating in Florida, where it became the state’s largest lobbying practice, and now aims to leverage its deep Sunshine State network at the federal level.
According to the firm’s own materials, its new D.C. office is led by industry veterans Daniel Diaz-Balart and Chase Kroll, whose experience covers defence, financial services, emerging technologies and foreign-affairs advocacy.
The timing of the launch coincides with the resurgence of Florida-linked figures into senior roles in the Trump administration, making the firm’s regional-to-federal transition particularly strategic.
In promoting itself, the firm emphasised that its Florida influence offers a “bridge” to national-level policy and regulation.
While the firm’s precise growth numbers and client list remain partially self-reported, the broader context of 2025 shows major lobbying houses benefitting from accelerating policy change in areas such as infrastructure, technology and trade.
For instance, other firms reported record-or-near-record third-quarter lobbying revenues in line with heightened corporate engagement with the Trump administration’s agenda.
Clients of The Southern Group and its new D.C. arm appear to draw from sectors such as aerospace & defence, emerging technology, financial services and cross-border trade.
The firm states it will increasingly focus on cutting-edge areas such as artificial intelligence, crypto and federal-contracting strategy, signalling an ambition to ride the next wave of regulatory and investment-policy activity.
As The Southern Group deepens its federal presence, the lobbying landscape in Washington is seeing intensified competition for access and influence.
The firm’s rapid move from state-level powerhouse to national player illustrates how advisory networks are adapting to the shifting dynamics of policy, investment and regulatory priorities in the early Trump years.
For TSG Advocates, converting early-stage growth into sustained mandates and visibility will be the next test of its federal strategy.
