Daniel A. Peterson handles a wide range of civil litigation matters, including personal injury and wrongful death claims, probate litigation, guardianships, breach of contract and other business disputes, trademark infringement matters and insurance coverage disputes. He also resolves land title issues for a national title insurance company and has worked extensively on major fraud and breach of fiduciary duty cases. 

Dan also assists clients dealing with environmental due diligence and real property remediation issues, putting to use his education and experience as a geologist.

Before pursuing a career in law, Dan earned two bachelors’ degrees—one in geology and the other in environmental studies--from Macalester College in St. Paul, Minnesota, followed by a master’s degree in geoscience from Pennsylvania State University. As a graduate teaching and research assistant at Penn State, Dan taught undergraduate geology courses and worked with a professor in designing and executing research projects. He also worked for the Pennsylvania Department of Conservation of Natural Resources, revising and updating geological maps, and later did field testing with a private sector environmental consulting firm working on brownfield redevelopment sites in New Jersey and New York.

Dan received a scholarship to the University of Minnesota Law School, graduating in 2012. During law school, Dan served as an advisor to first- and second-year law students participating in environmental moot court competition. He volunteered with the Minnesota Center for Environmental Advocacy monitoring and reporting on pending Minnesota environmental legislation. He also provided pro bono legal counseling through the Tubman organization for people facing family law and domestic violence crises.

After practicing immigration law at Mid-Minnesota Legal Aid and personal injury and worker’s compensation law at a small firm in Minneapolis, Dan joined McNally Peterson, S.C. in 2013.

Professional activities include participation in the Thomas E. Fairchild Inn of Court, the Milwaukee Bar Association and the Wisconsin Association for Justice. Dan continues to do community volunteer work with several organizations dedicated to urban renewal and neighborhood urban agriculture and food justice projects in Milwaukee.
