Meet The Team

  • The Great Big Tree Climbing Company consists of a small and close knit management team.

    Mark Hawes: Managing Director

    A former estate agent, who gave up a successful career in the city to start a new life and adventure in the countryside. “My wife and I were looking to start a family and wanted to look at life from a different perspective. I am pleased to say we have never looked back. We’re delighted by the way the company has grown and the diversity of clients it attracts… from businesses looking for an unusual team-building activity and schools creating educational fun and adventure in the forest to outdoor event days and children’s parties.”



Suzannah Denness, Business and Development Manager

After many years living in Hong Kong and working as the Director of Development for the British International School there, Suzannah and her family relocated back to the UK.  She joined the company in October 2015 and is very proud and excited to have played a major part in its growth and development since then.
