During his 22 year career, David has held management and executive level positions at companies in telecommunications, computing and interactive media, from Fortune 500 companies to mid-sized corporations.
David founded Trellist in 1995 with Pat Toman to capitalize on the market shift where corporate IT, marketing, advertising and operations were becoming increasingly interdependent on each other. The company was built in response to these changes and to create efficiencies that came from the balance of marketing, design and technology.
David serves on numerous regional advisory boards and is a frequent speaker at industry events. He is at the forefront of providing the thinking that many of today’s most influential thought leaders are talking about.
