Jeff Tammes started at Cornerstone 15 years ago in its New York flagship office, as one of the original members, where he launched and continues to lead the 'Create' division. Today, that division has grown across the agency's four offices worldwide, which includes New York, Los Angeles, London and recently opened in the spring of 2015, Sao Paulo. Tammes is also instrumental in the agency's 'Amplify' division, which complements the agency's creative work with digital, experiential, social, and public relations.

Cornerstone first built its reputation in the music community where its integrated approach and understanding of emerging culture was relied on to support the careers of artists. Tammes has been instrumental in its evolution to a multi-discipline agency that is now relied on by blue-chip brands to shape their positioning and story. Supporting the music community remains a vital part of Cornerstone and as such, Tammes has led pioneering music strategies for multiple brands that have shifted the paradigm of how artists and brands can work together. In 2007, he worked to create Mountain Dew’s Green Label Sound platform that the New York Times credited with “filling the void in the beleaguered music industry” and Dave 1 of Chromeo said “totally sets the blueprint of how bands and brands should work together."
In 2006, he executive produced the Grammy-nominated original song “Classic (Better Than I’ve Ever Been)” featuring Kanye West, Nas, KRS-One & Rakim as part of a campaign celebrating the 25th Anniversary of Nike’s Air Force 1 sneaker. He then later worked on the launch of Converse’s Three Artists. One Song and executive produced its first original installment featuring Julian Casablancas, Pharrell & Santigold. In 2007, Tammes Was named Brand Marketer of the Year by PR News. Other awards garnered by Tammes’ campaigns include Gold W3 (Bushmills), Gold W3 (Johnnie Walker), Gold W3 (Converse), Gold Digiday (Coca-Cola), and more.
