After nearly three years building the Fiber Broadband Association’s federal policy operation into one of Washington’s most recognized voices on connectivity infrastructure, Marissa Mitrovich has joined NextNav as Vice President of Government Affairs, where she will lead the company’s strategy and engagement with Capitol Hill, the Administration, and strategic advocacy partners.
Mitrovich brought two decades of government affairs and telecommunications experience to the Fiber Broadband Association when she joined in January 2023, and quickly established herself as one of the industry’s most effective advocates. The Hill named her one of Washington’s Top Lobbyists in 2023, 2024, and 2025, and Washingtonian recognized her among the capital’s most influential figures in the sector in both 2024 and 2025 – a back-to-back recognition that reflects the reach she built for the association during a pivotal period for broadband policy.
Named a Top Lobbyist by The Hill three years running, Mitrovich brought fiber broadband to the center of Washington’s connectivity debate – and now takes her advocacy playbook to the next frontier of positioning technology.
Before joining the Fiber Broadband Association, Mitrovich served as Vice President of Federal Legislative Affairs at Frontier Communications, and earlier as Vice President of Public Policy at Verizon, where she engaged with the administration on state government affairs and corporate responsibility. She also served as Vice President of Program Development at the Wireless Infrastructure Association, with a focus on workforce development and public-private partnerships.
At NextNav, she joins a company working at the intersection of spectrum, positioning technology, and national infrastructure – bringing the same policy firepower she applied to fiber broadband to a new set of challenges with significant implications for public safety, aviation, and the future of GPS resilience.
