When it comes to finding someone to explore a new river or jump on board for anything adventurous, Dave is the first in line and the best partner you could choose.

Working during the summers as he earned his degree from Brown University, Dave’s passion for the river never subsided.

Matt started rafting and kayaking in Colorado at the age of eighteen. Since that first summer on the rivers of the southwest, Matt has pursued his passion for running rivers around the globe. He has worked as a guide and led expeditions in numerous locations and can never seem to get enough. When not working on the river, you can find Matt looking for a ride to the put-in or tirelessly looking for new destinations for Global Descents. Matt and his wife Wendy call Embudo, New Mexico home and enjoys the rivers of the Southwest as much as possible.



Andrew "Sven" Bolton - Global Descents GuideAndrew “Sven” Bolton

Sven is yet another legendary guide that we are lucky to have running trips for Global Descents. If you have ever paddled in Zambia, Switzerland or Austria, chances are you’ve heard of Sven and he probably had something to do with the logistics of your trip. He is a magician when it comes to making things happen. With more than 20 years of river running experience and 15 of those on the Zambezi, Sven is an incredible addition to any trip we run. If you join us on the Zambezi, you’re sure to meet Sven and have the trip of a lifetime. Sven is also a budding politician whom we expect to make a run for Parliament sometime soon. When he’s not on the river or managing rafting operations, Sven enjoys exploring the Alps with his girlfriend, Andie.
