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. Jack has worked alongside his family to help grow their farming operation, which has evolved from a traditional dairy farm into a diversified agricultural business specializing in produce and floriculture. In April 2026, the farm expanded further with the planting of a 10-variety U-Pick apple orchard. Through his hands-on experience in agriculture and small business, Jack has firsthand knowledge of the challenges and opportunities facing local farmers, entrepreneurs, and working families.

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 extensive experience in higher education and mathematics instruction. Following graduate school, Jack joined the Department of Mathematical Sciences at the New Jersey Institute of Technology as an adjunct faculty member, teaching courses in mathematics and statistics. He also taught part-time at Rutgers University–Newark. In September 2026, Jack began serving as a full-time University Lecturer at NJIT, where he continues his work in higher education.

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 happily married to his wonderful wife, Andrea. Together, they share a deep commitment to family, faith, and community, and look forward to building their future in Sussex County.
