Jeff launched Dinner Party in 2017, with the aim of bringing together a streamlined and connected team of veteran strategists, creators and doers to turn big ideas into effective solutions for clients. Since its birth, the agency has worked with Michelob ULTRA, Diageo, Bandsintown, Success Academy and Comedy Wire.  Jeff leads the agency’s focus on creating long-lasting brand platforms and product innovation that go beyond “campaigns”.

One of Jeff’s biggest success stories to date, is the creation of  the ULTRA Brewing Collective for Michelob ULTRA. An innovation platform where beer and fitness collide to create new products with the goal of maintaining ULTRA’s leadership position and shaping the future of  the category. Dinner Party designed and built a creative hub in Colorado as part of the Collective, where it has hosted camps gathering innovative lifestyle brands, brewers, and fitness influencers for three days of ideation and creation.

Prior to launching Dinner Party, Jeff served as Chief Creative Officer at Cornerstone Agency. He was one of the agency's original members and launched and led the agency's integrated marketing group. While there, he grew the team across three global offices in NY, London and LA.

While there he specialized in creating integrated platforms that form community and build brands. Throughout his career, he has crafted the story and strategic approach for several award-winning campaigns including Since Way Back for Bushmills, Rubber Tracks for Converse, Don’t Steal Possible for Families for Excellent Schools, Share the Sound of an AIDS Free Generation for Coca-Cola, and Entourage for Johnnie Walker.

Jeff has also developed pioneering music strategies for multiple brands that are credited with shifting 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 also worked on the launch of Converse’s Three Artists, One Song and executive produced its first original installment featuring Pharrell, Julian Casablancas & Santigold.

When not steering the Dinner Party ship you can usually find Jeff, hanging with his wife and kids, cooking, moonshining, surfing, on his bike or nerding out while standing on line for some beer release.
