Meet the 2021 NPS Seasonal Rangers!

Seasonal Rangers at Mississippi National River and Recreation Area preform a variety of interpretive services including encouraging people at visitor centers to develop of sense of stewardship for park resources. They also lead bicycling tours, canoeing programs and other interpretive programs spending the majority of their time outdoors.

This is my first season with the National Park Service! I am originally from Green Bay, WI and graduated from University of Wisconsin-Eau Claire with a degree in Ecology & Environmental Biology. Since graduating, I've worked various jobs in the outdoor education field including Conservation Corps, Wilderness Inquiry, Long Lake Conservation Center in northern Minnesota, and the Center for Alaskan Coastal Studies in Homer, AK. My most recent position was working as a park ranger with the state park system in western Colorado. Outside of work I love to hike, bike, kayak and travel :)

I’m back for my third season with the park! As a local who grew up in the Twin Cities, this park is very much home to me and contains many of the sites that I am familiar with from my youth. The park is big enough though that there are still some unexplored corners left, but that list is getting smaller. I enjoy sharing the things that I have learned over the years and meeting the people who are just now exploring the park the way I did as a youth.

This year I’m going to be focused on our habitat restoration events. We have a lot of natural spaces within our urban park and it takes a lot of people to keep those natural spaces healthy. I will be one of the people providing guidance to our volunteers to help them with their efforts.


Brad Johnson has been a seasonal ranger twice with the park! He is out on a river in a kayak with other volunteers. He is also wearing his ranger uniform.

I am returning for a second season here at Mississippi National River and Recreation Area (MNRRA). I worked for a brief period at Olympic National Park in 2016. I also retired in 2016 after a 29-year career in law enforcement as a Conservation Officer with the Minnesota DNR. I had patrol assignments here in the Twin Cities that included parts of MNRRA, and St. Croix Scenic River. I also worked along the north shore of Lake Superior, which included the Superior National Forest and Boundary Waters Canoe Area Wilderness. While living on the north shore I served as a guest instructor/naturalist at Wolf Ridge Environmental Learning Center. I currently volunteer with two organizations here in the Twin Cities: The Raptor Center, and The Wildlife Rehabilitation Center.
