Why "The Mars Hill Group"?

In 2018 I had the opportunity to lead a team development session in Athens. My wife accompanied me on this trip and we extended our stay to explore Greece. It was incredible.

One of the highlights of the trip, outside of working with an amazing international team, was visiting the ancient ruins. One place of particular interest to me was the Areopogas, otherwise known as "Mars Hill".

Mars Hill has a significant history, it is where the King's advisors met, where great minds gathered to discourse and exchange ideas, and it is where the Apostle Paul met and reasoned with Greeks on his missionary journey (Acts 17). Geographically, it is an enormous rock outcropping adjacent to the Parthenon that overlooks the city of Athens.

Walking on Mars Hill is an experience I will never forget. Less than a year later when I was contemplating names for our consulting firm, Mars Hill seemed like a natural fit. I would like to bring the spirit of dialogue that took place on Mars Hill to the work I do.
