Donna Rozar

Donna Mummau Rozar (née Mummau; born February 9, 1950) is an American businesswoman, nurse, and Republican politician from Marshfield, Wisconsin. She served two terms as a member of the Wisconsin State Assembly, representing Wisconsin's 69th Assembly district from 2021 to 2025. She is also a member of the board of supervisors of Wood County, Wisconsin, since 2000.

Early life and career Donna Rozar was born Donna Kay Mummau in Lancaster, Pennsylvania, and moved with her parents to Orange County, Virginia, where her father had purchased a farm. She grew up on the farm and graduated from Orange County High School in 1968. In 1971, she earned her nursing diploma from the Virginia Baptist Hospital School of Nursing, in Lynchburg, Virginia. She then worked a year as an emergency room nurse at the University of Virginia Hospital in Charlottesville, where she earned her nurse practitioner certificate. For the next five years, she worked as a nurse practitioner at Norfolk General Hospital, where she met her future husband, Dr. Ed Rozar. Her nursing license expired in Wisconsin in 2022 and she no longer holds an active nursing license. and moved with him to Knoxville, Tennessee. There she attended the University of Tennessee and earned her bachelor's degree in nursing in 1981. The couple moved frequently, living in Dallas, Texas, Pittsburgh, Pennsylvania, and Morgantown, West Virginia, over the next decade, adopting children along the way. They finally moved to Marshfield, Wisconsin, in 1988, where Ed was diagnosed with HIV/AIDS in 1989.

Less than four months later, in February 1995, Rozar jumped into another campaign, running in the special election in the 24th State Senate district to replace state senator David Helbach, who resigned unexpectedly at the beginning of the 1995–1996 term. Again, Rozar was defeated, taking just 43% of the vote in the May 1995 special election.

After 1996, Rozar took a brief pause from seeking elected office, but remained active politically as an officer in the Republican Party of Wood County and as president of the Marshfield Woman's Club. Additionally, Rozar served on state and local commissions by appointment. Governor Tommy Thompson appointed her to the state Examining Board of Architects, Landscape Architects, Professional Geologists, Professional Engineers, Designers, and Land Surveyors in 1996; the Marshfield City Council appointed her to the local Cable Committee in 1997. She also became associated with a local organization known as People Interested in Clean Air, which pressed the city of Marshfield for a ban on smoking in restaurants.

In April 2000, Rozar achieved her first elected office when she was elected to the Wood County Board of Supervisors, though she did not face an opponent in the race. A month later, at the Republican congressional district caucuses, Rozar was elected as a delegate supporting George W. Bush for the 2000 Republican National Convention. Rozar ran for a seat on the Marshfield Common Council in 2001, but fell 100 votes short of her opponent.

In 2003, the 24th senate district became vacant again when state senator Kevin Shibilski was appointed Secretary of Tourism in the newly inaugurated administration of Governor Jim Doyle. Rozar again sought the seat, but was once again defeated, this time receiving less than 30% in the April special election.

Following her loss in 2003, Rozar returned to nursing full time in 2003, working as a cardiac medical-surgical nurse at St. Joseph's Hospital in Chippewa Falls, Wisconsin, and then at Marshfield Medical Center. She also pursued her master's in nursing from Viterbo University, completing the degree program in 2008. In April 2020, after winning reelection to her 11th term on the Wood County Board, Rozar announced she would be a candidate for Wisconsin State Assembly in the 69th district. She faced a crowded Republican primary field, but prevailed over her three opponents with 53% of the primary vote. In the general election she faced Brian Giles, a truck driver and first-time candidate. In November, she won 65% of the vote and, on her fifth attempt, was elected to the Wisconsin Legislature.

After the 2024 redistricting, Rozar was drawn out of her 69th Assembly district seat. Under the new plan, she faced an incumbent-vs-incumbent primary election against John Spiros in the new 86th Assembly district. Spiros prevailed in the primary with 43% of the vote, with a third candidate, Trine Spindler, receiving 25%.

Personal life and family Donna Kay Mummau took the last name Rozar when she married Dr. Ed Rozar in 1993. Together they adopted five children who are now grown. Ed was a medical doctor and contracted HIV from a patient sometime in the mid 1980s. He died of AIDS-related complications in 1993.

She is a member of the Wisconsin Nursing Association, the American Nursing Association, the American Nurses Credentialing Center, and the Sigma Theta Tau nursing honor society.
