AJ Koch

Retail Associate

I have been around water most of my life as a competitive swimmer, a lifeguard, and since 2014, a diver. I am a level 2 diver. The first time that I dove I was hooked because of the feeling of being free and the opportunity to explore new things.

Jamie Nieuwenhuis

Retail Associate

I have always been in love with water ever since I was a kid. My grandma always said I was a fish born in a human’s body. While traveling the world I completed my open water certification in Thailand. I can’t wait to see what the dive future holds for me.

JoAnn Haack

Project Manager
Advanced Open Water Instructor

I have always been drawn to the underwater world and the beauty I’ve seen in pictures and movies. Once I learned it’s possible to dive in Iowa, I never looked back. As a level 8 diver, I have helped many new divers take their first breaths underwater and have taught ages 10 to 66 since becoming a dive professional in 2008.

Marty Bunge

Store Manager

Marty’s love of diving began in 2015 when he traveled to Roatan after earning his open water certification. Since then he’s been to Hawaii and Cayman Brac. A level 3 diver, Marty hopes to eventually earn his instructor certification. When he’s not planning a dive trip, he’s either riding gravel roads on his bicycle, or off somewhere hiking or camping.

Nate Northup

Retail Associate

Growing up in the woods and waters of Wisconsin, I learned to love life in, on, and around water. From diving the Great Lakes to fishing, ice fishing, sailing, and canoeing – there’s not much I don’t enjoy when it comes to water! With a background in teaching, I completed open water certification in college and have been diving ever since. I’m a level 1 diver and always looking to further my experience. Let’s go diving!
