A thought leader and coauthor of Legacy in the Making: Building a Long-Term Brand to Stand Out in a Short-Term World, Mark founded Team One’s award-winning brand consultancy, The Legacy Lab, in 2012 to inspire ambitious leaders of enduring brands. In 2023, the Legacy in the Making docuseries was released, exploring stories of companies that found their key to ongoing success.

Mark introduced The Legacy Lab’s annual index, The Legacy Makers 100, which identifies brands striving to shape a better future while delivering high-caliber products––an objective that is at times at odds with itself and is increasingly falling by the wayside in today's business landscape.

Mark's commitment to encouraging future leaders to pursue their passions and to make a lasting impact is a prominent source of Team One's culture. The agency has received numerous accolades that recognize its exceptional culture, including Ad Age's "Best Places to Work" in 2024.
