David Steffen

David Steffen (born October 12, 1971) is an American businessman and Republican politician from Green Bay, Wisconsin. He is a member of the Wisconsin State Assembly, representing Wisconsin's 4th Assembly district since 2015. He also played an important role in the 2001–2003 renovation of Lambeau Field.

Early life and career David Steffen was born on October 12, 1971, in Ashwaubenon, Wisconsin. During his teenage years he attended Ashwaubenon High School, graduating in 1990. Following his graduation from high school he attended the University of Wisconsin–Madison, where he obtained a bachelor of arts degree in political science, graduating in 1995. Following his graduation, Steffen did work in the private sector and acted as a lobbyist for several years.

In 2000, Steffen, then executive director of Team Lambeau–an organization founded to keep Lambeau Field open–was hired by the Green Bay Packers to help them attain a $295 million expansion of the field. The proposal, passed by the state legislature, involved implementing a 0.5% sales tax in Brown County, as well as additional fees on personal seat licenses on season ticket holders. The proposal was then ratified by voters in Brown County with a 53%-47% margin.

During his time in education and non-profit sectors, he served as Director of Operations for the Legislative Leadership Institute Academy of Foreign Affairs in partnership with the Irish American University located in Dublin, Ireland.

In 2020, Steffen proposed legislation that would dissolve the Lambeau Field Stadium District, which maintains the stadium at Lambeau Field. His proposal would additionally transfer ownership of the field to Green Bay, Wisconsin and see funds and assets redistributed to residents of the city and surrounding county. Steffen argued that the legislation would simplify the financial situation between the city and the Green Bay Packers and eliminate administrative costs. He also argued that the district had served its purpose and completed all of the objectives which had been assigned to it by the legislature upon its creation. To avoid a lawsuit, Steffen withdrew his proposal in exchange for further agreements regarding transparency and oversight of the board.

Following the defeat of Donald Trump in the 2020 presidential election, Steffen joined other Republicans in efforts to attempts to overturn the 2020 presidential election.

In 2024, Steffen faced vice chair of the Oconto County Republican Party Darwin Behnke, the father of fellow representative Elijah Behnke. During the campaign, Steffen criticized Behnke's campaign for financial issues. The campaign also proved to be divisive at the county level, as Steffen had the support of the Brown County Republicans whereas Behnke drew support from the Oconto County Republicans.
