About Justin

I build businesses because I'm unemployable.

Today, I'm the CEO and founder of LeadMD, the world’s most trusted marketing operations agency. We focus on transforming marketing into a revenue center and specialize in Marketo, Engagio & to make it all work.

In addition to LeadMD, I also co-founded a SaaS payment technology provider,
and Greyson Organics, an organic farm in rural Missouri with my father.

That brings us to the present where I'm launching an edtech startup (still in private beta) to distribute the wealth of knowledge and best practices LeadMD has established over the years. We call it Six Bricks.

Finally, I love learning, the written word and talking to business leaders and practitioners alike. In 2008 I left my job as a VP of Marketing and Sales in a small niche industry with almost no personal platform. Today, I've become a recognized speaker and author published 400+ times in major publications. In 2017 I embarked on my own column, 'Tribal Leadership', in Inc. while maintaining features in Entrepreneur, TechCrunch and others. My wife Jennifer is a saint. We are expecting our first, a son, literally any day now.

Give us a shout

We would love to hear from you, just don't waste our time.
