Working with political and nonprofit leaders from London to Cape Town and Medellín to Mumbai, he helped advance initiatives to preserve urban natural areas and restore ecological connectivity.

From 2009 to 2014, Jon helped extend the legacy of the renowned Murie family of conservationists and the Murie Ranch in Wyoming’s Grand Teton National Park, one of North America’s most influential centers for conservation leadership. After joining the organization as Programs Manager, he was named Executive Director of the Murie Center, serving in that role from 2011 to 2014.

Earlier in his career, Jon directed communications for the Chambers of Commerce in Jackson Hole, Wyoming, and Park City, Utah, where he contributed to community and economic development while promoting conservation values and responsible tourism.

David Nielsen

Director of Operations

David spent 35 years at the University of Nebraska at Omaha’s College of Business Administration, with his last role as Assistant Dean. Throughout his career, he played a key role in managing multi-million-dollar budgets, overseeing technology infrastructure and facility operations, and leading administrative and Operations staff for Mammel Hall. He also initiated efforts to enhance the student experience and increase the college’s community impact. Additionally, he served as project manager for several major construction projects, helping to turn new academic and research spaces from concept to completion.

Nisswa has been a part of David’s life for over four decades. Since 1981, he and his family have spent their summers at their cabin on the lake, creating countless memories and strengthening their love for the natural beauty of northern Minnesota. That lifelong bond made the move to the Brainerd Lakes area a natural next chapter.

David and his wife, Beanie, are now proud to call this community home. Beanie shares his passion for the outdoors and is an accomplished nature photographer. Together, they spend much of their free time exploring the lakes, capturing wildlife through the lens, and connecting with others who share their appreciation for Minnesota’s landscapes and wildlife. Their son, Steven, also loves spending time in the Lakes Area, where the family enjoys discovering the region’s unique restaurants, stores, craft breweries, and spending time on the water. In every season, David enjoys exploring nature year-round—running local trails, snowshoeing through winter landscapes, and ending many evenings with a paddle at sunset.

During her time in the North Woods, she has come to understand the ecological and cultural importance of loons and she is excited to become a part of an organization that emphasizes this importance. 

Maddi’s educational background in Environmental Studies has prepared her for the challenge of reaching out to the Crosslake community and beyond to advocate for the protection of local wildlife. Since joining the team in 2023 as a MN GreenCorps member, she has continued to share her passion for wildlife and the outdoors with the Crosslake area and beyond through outreach and NLC programs. Aside from loon-watching, Maddi can often be found off the grid with a canoe and fishing rod, or talking to trees and local squirrels.

Olivia Guenzel

Olivia grew up in the Twin Cities with a cabin up north that she would return to every summer with fond memories and a love for the ample nature and wildlife found in the northwoods. 

Olivia graduated from Ohio Wesleyan University in 2023 with a degree in Environmental Studies and Spanish. Her experience and love for working with animals grew even further through internships and a manager position at the Minnesota Wildlife Rehabilitation Center during her college years and after graduation. Olivia joined the National Loon Center in the spring of 2024 as a programs intern and in the fall became a part of the team full-time as the Visitor Services and Operations Coordinator.

In her free time she loves spending time with her 4 cats, gardening, hiking, exploring Minnesota state parks, birdwatching, and taking photos.

Baylee Bessingpas

Minnesota GreenCorps Member

Baylee grew up in the Brainerd Lakes area listening to loon songs, catching minnows and frogs, climbing trees, and devouring every book about animals she could get her hands on! A lifelong fascination with nature and desire to protect and share its wonders led to her pursuing a B.S degree in Fisheries, Wildlife, and Conservation Biology from the University of Minnesota – Twin Cities, where she graduated in 2019. She discovered her passion for education while teaching a zoology lab in college and interning at the International Wolf Center, and has developed a strong scientific background working on wildlife research projects around the country. Most recently, she was a technician for the Oregon Department of Fish and Wildlife working on a study of fisher and gray fox interactions. She is very interested in community ecology and bridging the gaps between science, management, and how the public perceives and interacts with nature. 

Baylee spent the summer of 2025 volunteering with the National Loon Center as a StewardShip guide, and had an absolute hoot sharing the joy of loons and freshwater ecology with the public! She is thrilled to join the NLC team as a GreenCorps member for the 2025-2026 term and continue to connect with the greater Crosslake community and advocate for the stewardship and conservation of loons and lakes. In her free time, you can usually find Baylee with binoculars in one hand and a camera in the other, observing wildlife and enjoying the fresh air! She loves reading fantasy novels, swimming and paddling, and learning new things.

Lucy Bock

Partnerships & Development Manager

Lucy graduated from St. Olaf College with a Bachelor of Arts in English, where she developed a passion for storytelling, communication, and connecting people through shared experiences. She brings those skills to her work every day, helping cultivate partnerships that inspire support for loon conservation, education, and research.

The Brainerd Lakes Area has held a special place in Lucy’s heart since childhood. She spent her summers at her grandparents’ cabin on the Whitefish Chain, creating lasting memories on the water and developing a deep appreciation for Minnesota’s lakes and natural landscapes. Those experiences fostered a lifelong connection to the area and a commitment to preserving its unique beauty for future generations.

Outside of work, Lucy enjoys spending as much time outdoors as possible. Whether hiking, exploring the lakes by boat, or simply taking in the natural beauty of northern Minnesota, she is happiest when immersed in nature. She also loves cooking, gathering with friends and family, and creating opportunities to connect with the people she cares about. Her love for the region, its wildlife, and its communities makes her especially proud to support the National Loon Center and its vision for the future.
