MASON CITY — Donald “Don” Nelson, 89, a longtime Mason City City Council member, former YMCA executive director and familiar figure in local government whose decades of public service touched generations of northern Iowans, passed away peacefully at his Mason City home on Tuesday, November 3, 2026, under the care of MercyOne North Iowa Hospice. Nelson, who represented Mason City’s Third Ward for 12 years, was known for his willingness to speak his mind, his commitment to local recreation and youth programs, and his dedication to the people he served.
A celebration of life will be held at 11 a.m. Wednesday, November 11, 2026, at Hogan-Bremer-Moore Colonial Chapel, 126 Third Street NE in Mason City, with Pastor Beverly Butler of Trinity Lutheran Church officiating. Visitation will begin at 10 a.m., one hour before the service. Burial will follow at Elmwood-St. Joseph Cemetery in Mason City.
For many longtime Mason City residents, Nelson was much more than a name on a City Council agenda. He was a familiar presence at City Hall, a former leader of the local YMCA, a supporter of athletics and recreation, and a man who believed that serving a community meant listening to the people who lived there.
His years in public office coincided with important debates over Mason City’s future, including downtown development, municipal spending, recreational facilities, neighborhood conditions and the direction of city government.
NorthIowaToday.com covered Nelson extensively during the final years of his council service, documenting a public official who was willing to ask questions, challenge proposals and occasionally disagree with his colleagues.
Nelson was elected to three terms representing the city’s Third Ward, serving approximately 1999 through 2011. His departure from elected office did not mark the end of his involvement in city affairs.
In October 2011, NIT reported that Nelson had decided to seek a seat on the Mason City Parks and Recreation Board as a write-in candidate. He had already spent years advocating for improvements to the city’s parks and recreational opportunities.
Among his accomplishments was helping establish the Volunteer Park Watch Program in 2006 alongside fellow Councilman Jeff Marsters. The initiative was designed to discourage vandalism and protect public parks while placing little financial burden on taxpayers.
In announcing his Parks Board candidacy, Nelson reflected on his 12 years on the council and said the experience had given him opportunities to make constructive contributions to the community.
His 2011 announcement, documented by NorthIowaToday.com, also offered a remarkable accounting of his community involvement.
In addition to 12 years on the City Council, Nelson listed 12 years on the Mason City Civil Service Commission, six years on the Good Shepherd Health Center Board of Directors, three years with the North Iowa Corridor economic development organization and nine years on the Iowa Games Board of Directors.
He also had served nearly two decades as executive director of the Mason City YMCA.
That lengthy record helps explain why Nelson considered community service such an important part of his identity. His family says he took particular pride in dedicating 37 years to civic involvement and service on various boards.
Nelson’s approach to city government could be seen in a November 2010 initiative that placed residents directly into the discussion over Mason City’s future.
Rather than simply relying on the annual City Council planning process, Nelson distributed his own questionnaire seeking public input ahead of the council’s goal-setting session.
He wanted residents to identify the city’s most important priorities, recommend additional services and policies, and consider the challenges and opportunities Mason City might face over the next five to ten years.
He also invited comments on downtown development, a possible multipurpose center, infrastructure, property maintenance, community amenities and taxes.
Residents were allowed to respond anonymously.
It was a practical reflection of Nelson’s belief that ordinary citizens deserved an opportunity to be heard before decisions were made on their behalf.
Nelson was particularly outspoken during discussions about a proposed multipurpose arena in Mason City.
In August 2011, NIT reported that Nelson called for a public referendum on the proposed arena, arguing that voters should have a direct say if the project moved forward.
He expressed concerns about the city’s declining youth population and questioned the financial assumptions behind the proposal.
Nelson and Marsters also raised questions about the consolidation of tax increment financing districts and whether the changes could help support a future arena project. Other council members disputed their interpretation, and the consolidation ultimately passed unanimously.
The episode reflected the sometimes contentious nature of Mason City government during that period. Nelson did not always agree with colleagues, but he was willing to put his concerns on the public record.
Another example came in April 2011, when Nelson sought an investigation into a possible conflict of interest involving fellow Councilman Scott Tornquist.
The dispute involved Tornquist’s business connections to companies that provided materials for the Mason City Public Library project and his participation in council votes on related expenditures.
Nelson wrote to City Attorney Tom Meyer requesting an examination of the matter and indicated that he intended to pursue his concerns with the Iowa Attorney General’s Office. Tornquist declined comment to NIT at the time.
It was another instance in which Nelson publicly questioned the conduct of city government, even when doing so placed him at odds with another elected official.
Not every disagreement involved a major development project.
In June 2011, Nelson challenged an inaccurate population-loss figure cited during a council discussion, pointing to census figures to correct the record.
For Nelson, the details mattered, whether the subject was a multimillion-dollar development proposal or the actual number of residents living in the community.
When his final council term ended in December 2011, Nelson thanked the people of Mason City for electing him three times. During his farewell remarks, he described public service as both educational and rewarding and expressed appreciation for city employees who had responded to his many requests and memoranda.
He subsequently continued his involvement through the Parks and Recreation Board, where discussions about neighborhood recreational facilities and public improvements remained part of his community work.
Long before Nelson became a familiar face at City Hall, however, he had built a career around another form of community service: giving children and families a place to belong.
Born November 13, 1936, Nelson was the son of Harry and Fern (Bowers) Nelson of Eagle Grove, Iowa.
His family encouraged an appreciation for wrestling at an early age, and the sport became a lifelong passion.
After graduating from Eagle Grove High School, Nelson attended Iowa State University, where he earned a varsity letter in wrestling.
Despite his Iowa State education and athletic accomplishments, he remained a devoted fan of the University of Iowa Hawkeyes.
His professional career eventually took him well beyond Iowa.
Nelson served as an executive director at YMCA locations in Cleveland and Akron, Ohio, and Elgin, Illinois, before returning to Mason City, where he spent approximately 19 years leading the local YMCA.
His family remembers those years as an especially meaningful chapter of his life.
Nelson believed every child should have an opportunity to participate in YMCA activities, regardless of the difficulties or circumstances a youngster might face at home.
He worked to make those opportunities available and believed in treating people with dignity and respect.
The YMCA was more than a recreational facility to him. It was a place where children could build confidence, develop friendships, stay active and find encouragement.
That commitment also shaped his later work in public office.
His interest in parks, youth recreation and community facilities was consistent with the values he had promoted throughout his YMCA career.
Nelson remained a source of institutional knowledge about the organization after his retirement.
In an August 2012 NIT report involving concerns about supervision at the YMCA, the former director emphasized the importance of protecting young people in facilities shared by adults and children.
“I think all facilities where you have children and adults have to be supervised,” Nelson told NorthIowaToday.com.
It was a straightforward statement from someone who had spent much of his working life responsible for the well-being of children and families.
Beyond his public responsibilities, Nelson was remembered as a thoughtful man who made an effort to recognize the achievements of others.
His family recalled his habit of sending congratulatory letters to people who reached important milestones.
A young athlete competing at a state tournament, an employee receiving a promotion or someone celebrating a personal accomplishment could find a letter from Nelson acknowledging the occasion.
Those gestures, often made without fanfare, reflected his appreciation for hard work and individual achievement.
Sports remained an important part of his personal life.
Nelson enjoyed football and baseball and was particularly devoted to the Cleveland Browns and the Cleveland Indians, loyalties that reflected his years living and working in Ohio.
He also enjoyed the excitement of March Madness, with annual family gatherings in Las Vegas becoming a cherished tradition.
An occasional casino visit was another pleasure, although his family recalled that he generally knew when to leave before losing too much money.
His loved ones acknowledged that Don could be stubborn, a characteristic that those familiar with his years at City Hall might recognize.
But they also remembered the warmth beneath that determination: a man who cared deeply about others, offered help when it was needed and valued the relationships he built throughout his life.
On October 11, 1996, Nelson married Mary Beth Larson after the couple had already been together for eight years. Their relationship spanned 38 years, filled with family, companionship and shared experiences.
Nelson is survived by his wife, Mary Beth Nelson; his children, Todd Nelson, Kim Brown, Sean (Robin Hulshizer) Nelson, Ben (Melissa) Swyter and Casey (Katie) Swyter; 12 grandchildren; and six great-grandchildren.
Other survivors include his brother-in-law, Phil Elrod, along with extended family members and friends.
He was preceded in death by his parents, Harry and Fern Nelson, and his siblings, Phyllis Wobbeking, Nada Mattie, Harry Nelson, Bill Nelson, Dale Nelson and Mary Ann Elrod.
The YMCA staff and board have already expressed sympathy to Nelson’s family through memorial tributes, a reflection of the ties he maintained with the organization he served for so many years.

Mason City’s history is shaped not only by its mayors and major development projects, but also by people who dedicate years of their lives to the everyday work of making a community function.
Don Nelson was one of those people.
He served on committees and boards, attended meetings, questioned decisions, advocated for recreational opportunities and encouraged residents to participate in local government.
He devoted years to helping children through the YMCA and continued that commitment through parks and public service. He recognized the accomplishments of others with a personal letter and remained an enthusiastic sports fan throughout his life.
And for those who followed Mason City government during his years in office, his name remains part of the city’s political history, including the debates and decisions that helped shape the community.
His service extended beyond any one council vote, board appointment or public disagreement.
The lasting measure of Don Nelson’s life can also be found in the children who benefited from the YMCA, the neighbors who enjoyed the city’s parks, the people whose accomplishments he took time to recognize and the family and friends who knew the man behind the public office.
