Meet Jack DeGroot

Jack DeGroot was elected to the Sussex County Board of County Commissioners on November 7, 2023 and sworn in on January 1, 2024. Raised on his family’s dairy farm in Wantage, Jack brings a lifelong connection to agriculture, small business, and the rural character that defines Sussex County. He continues to work on and help expand his family’s farming operation, which has grown from a traditional dairy farm into a produce, floriculture farm that is introducing an apple orchard coming Spring of 2026. Jack has firsthand experience with the challenges facing local farmers and entrepreneurs.

Jack began his public service and leadership journey at an early age through more than a decade of involvement with Sussex County 4-H, where he developed a strong foundation of community service, stewardship, and leadership. A 2017 graduate of High Point Regional High School, Jack distinguished himself both academically and athletically, becoming the school’s first 1,000-point basketball scorer in over a decade.

Jack earned a Bachelor of Science degree in Mathematics and Finance from Marywood University in 2021, followed by a Master’s degree in Statistics from the University of New Hampshire in September 2023. While at UNH, he served as a full-time Teaching Assistant and later as an Instructor, gaining valuable experience in higher education. Jack currently serves as an adjunct faculty member in the Department of Mathematical Sciences at the New Jersey Institute of Technology, where he teaches statistics & calculus, and also teaches part time at Rutgers University–Newark.

Before being elected to county office, Jack worked in the Office of New Hampshire Governor Christopher T. Sununu, where he conducted policy research, analyzed pending legislation, and performed statistical and data analysis for state departments. In this role, he worked closely with executive staff and agency leadership, gaining insight into responsible budgeting, data-driven policy decisions, and effective government operations under one of the nation’s most fiscally disciplined administrations.

As a County Commissioner, Jack has focused on farmland preservation, agricultural innovation, education, and responsible fiscal stewardship. He has worked collaboratively with fellow commissioners, municipal leaders, and regional partners such as North Jersey Transportation Planning Authority to strengthen Sussex County’s agricultural economy, support local businesses, and protect the county’s rural character for future generations. His work has earned statewide recognition, including consecutive placements on New Jersey’s Insider 100: Rising Generations list.

Inspired by his devotion to Jesus Christ, Jack approaches leadership and life with a commitment to integrity, humility, and faithfully serving those around him. He resides in Wantage and is engaged to his wonderful fiancée, Andrea. Together, they share a deep commitment to family, faith, and community, and look forward to building their future in Sussex County.
