He has so many funny stories about his experiences paddling rivers that he can keep you entertained for hours. If you have a chance to spend time with him, be sure to ask him about being chased by killer bees, getting lost in the jungle after losing his boat or having to hike out of the jungle because the water was too high to safely run.

He has an amazing family and two young boys who are full of energy and you’ll always find a smile on his face.

He knows the rivers of Costa Rica as well as anyone in the country and has guided hundreds of trips along the rivers of Costa Rica. He is an incredible teacher and loves working with newer kayakers to help them gain confidence on the river.

Trip Leader, Guide and Kayak Instructor

Deivis grew up on the outskirts of Turrialba and has been a top competitor in many national Triathlons including TicoMan. He loves the outdoors and also serves as a volunteer in the local fire department. He is an exceptional kayaker and river guide and has represented Costa Rica multiple times in the World Rafting Championships. He has completed ACA’s Swiftwater training and loves helping others learn to be more confident and safe on the river.

If you are kayaking behind Deivis, he will show you the best lines down difficult stretches of a river and is exactly the type of person you want to paddle with if you are looking to improve your skills.

And… he has great rescue skills. His favorite rescue happened when he was paddling on a Class V section of river and he saw a sloth that accidentally swam through an entire Class V rapid. It was stuck clinging to a rock in the rapids. Yes, that is a picture of the sloth that Deivis was able to save.

Unfortunately we aren’t aware of any life jackets made for sloths, but luckily after he helped paddle the sloth to safety, the sloth gave him a smile and slowly headed on its way, grateful to be back on dry land.
