About Us

At Vanguard Government Relations, we are experts at helping our clients navigate through the federal landscape in Washington by developing and implementing customized, creative and effective strategies that solve problems and create opportunities.


As one of the leading bipartisan government relations firms our team is consistently ranked among Washington’s best. We know how Washington policymakers make decisions because we’ve been there. We’ve assembled an exceptional team of Washington’s brightest professionals who fully engage across all government, building the kind of momentum that successfully penetrates through the clutter and chatter to achieve our clients’ goals and protect their interests.


Our clients are as diverse as high-tech entrepreneurs and groundbreaking start-ups to global brand names to national non-profits, universities and trade associations. Our professionals, both Republicans and Democrats, include former senior Congressional staff, Administration officials, retired military officers, scientists, and business executives. Cassidy professionals work as a team to ensure that all policy and political skills are made available to achieve our clients’ goals.


Our team readily adapts to an ever-changing landscape, regardless of the existing political environment, budgetary conditions or politics of the day. We know how government works, who makes it work, and how to make it work successfully on behalf of our clients.


We are strategic advisors and advocates who educate and empower federal decision makers with the facts, insights and strategies to make well-informed decisions that will advance and protect our clients’ business and institutional development goals.

From our multidisciplinary perspective—which brings together our unparalleled understanding of law, business and policy—to the deep connections we cultivate across the industries and communities you’re a part of, we have a unique ability to see the bigger picture: and serve you better for it.


These advantages, along with our tenacious, never-say-no style, are why we’re the go-to firm for your toughest matters. Because at Vanguard Government Relations, we’re relentlessly driven to deliver the results you deserve—and get the job done right.
