Marc Green

I founded Green Divers Tulum (GDT) in 2015 - GDT is a small, professional dive operation with me as the main dive guide and instructor. Currently, I am training for my certification as a Full Cave Instructor. My goal is to show both new and experienced divers the beauty of the underwater world. I wish to share my experience and to give divers the knowledge needed to be self-sufficient and competent when diving. 

My first open water dive was in Vietnam in 2004. Since then, I have dived on four continents. I completed my Full Cave Diver in 2011. Besides diving and especially cave diving, I love to travel to far corners of the world and if the travels can be combined with hiking, then even better. I'm a bit of a football fan and enjoy watching a good crime drama with a proper cuppa of tea. I am originally from England but have lived in Mexico since 2009.

I started diving in 2003... A Discover Scuba in Australia. I did my open water course here in Tulum the next year and have continued recreational diving since then. I am originally from Denmark but do not dive there because it is too cold.
