The On and Off River Team


Alex Maier

Alex is an outdoor documentary filmmaker and thru-hiker. His first film and long hike was in 2015 on the Pacific Northwest Trail. That hike changed his whole outlook on life and he has been working towards a career in outdoor filmmaking ever since. He went on to produce two more documentaries, one about the North Country Trail and another about the Hayduke Trail. Now he’s working on a fourth on the Continental Divide Trail with his girlfriend Amy Robin. Alex is interested in using nature and his movies as a tool to explore human consciousness and personal growth. Dale first learned about Alex through his YouTube Channel, Wilderness Mindset, and after being interviewed for his new film Mind, Body and Soul. He is also Co-CEO/ Owner, of Wide Range Multimedia, LLC. Alex personifies excellence in nature and he was the biggest asset on the crew team.

Amy L. Robin

Amy is a photographer, videographer, and adventurer. She’s always been interested in cameras and nature. She seems to think they go hand in hand, and growing up in Montana gave her plenty of opportunities to put those two together with years of experience.

Amy has combined forces with her boyfriend, Alex Maier, to create Wilderness Mindset. They’re planning their next personal documentary called Mind, Body, and Soul: The Nature of Well-Being. Amy believes in the power of nature so much that she’s decided to be vulnerable to show how nature can help heal the mind, body, and soul through a personal and private perspective. You can follow both Wilderness Mindset and Mind Body Soul Film on Facebook and Instagram.

You will rarely meet Amy without her best friend Minnow being somewhere nearby. Where one goes, the other will follow. Together they are unstoppable and are ready for almost any adventure.

Amy doing her thing!


Zak Rivers

Zak is an award-winning Photographer, Filmmaker, and Musician from Mankato, MN. While his client base is largely from MN, he has adventured and shot in Zion Natl. Park, Mt. Hood, the MN Boundary Waters, Cambodia, Big Bear CA, and recently Nepal/Mt. Everest. A professional photographer like no other. As Zak put it: “With an interest in a source-to-sea paddle of the Mississippi, I was introduced to Dale Sanders, a world record holder and paddler from Memphis. The spark of Dales backstory, upcoming Source-To-Sea world record attempt as the oldest human to through-paddle the length of the Mississippi, and ever present charisma was enough to convince me that an award winning Documentary could potentially be made.”

Graphic Artist

Lauren Maier

Lauren grew up outside. The extreme seasons of Wisconsin lend themselves to a number of outdoor activities and she’s been recording that time outside through photography since she was ten. Since those early, Midwest days, she has lived in Colorado, Oregon, New Zealand, Australia, Montana, and currently, Alaska. With each move, she is met with a whole different set of creative challenges and endless rewards that have evolved both her photographic skills and have sparked interest in just about every other form of visual and written art. 

Art is all about storytelling and the best thing for any story is the meshing of art forms. Film meets writing meets digital art meets animation. It’s this combination and collaboration that makes an already great story beautiful.
