About Us

Founded in 2006, Amsterdam Group Public Relations Inc. was established to strike a delicate balance between contemporary world-wide-web branding and cutting-edge, next generation social media engagement with the established and highly accredited practice of media relations and traditional thought leadership promotion.

We secure bold positioning around the world, crafting an indelible imprint with prominent audiences for our clientele, which include and have included Georgian Prime Minister Bidzina Ivanishvili’s “Georgian Dream” campaign, former YUKOS head Mikhail Khordorkovsky, Zimbabwean Prime Minister Morgan Tsvangarai, former Nigerian Governor and oil shipping magnate Dr. Orji Uzor Kalu, the Arcadia Foundation, MYUTIQ, First International Bank, Families USA, Zimbabwean Sport and Education Minister David Coltart, and a range of other government officials and agencies.

Our practice carries weight at the highest levels of international governance. We have developed a unique reputation and subsequently, sterling relationships with the influencers of today that have enabled our company to work collaboratively with our clients well beyond the preset terms of any consultancy agreement.

Amsterdam Group boasts an unprecedented practice. Whereas most industry majors prioritize seeking new business over servicing clients, Amsterdam Group places a value on service.

Our team has further spoken around the world on the value of social media engagement and citizen journalism, ensuring concurrently that our clients regularly have the world-wide-web in focus while their voices resonate in established media outlets, such as the New York Times, Financial Times, Wall Street Journal, Sky News, the BBC, and the Economist.

Our public relations firm has a broad history of cooperation in Europe, North America, Eurasia, Latin America, Asia and Africa.

Our value-focused Social Media Public Relations approach leverages existing contacts throughout these regions while forging and cultivating new relationships with reporters, editors, think tank senior fellows, and policy makers on behalf of a clientele we are proud to consider an integral part of our team and its thought stewardship.
