    Biography

    Kristen J. Hassebrook initially joined Mueller Robak in November of 2022. She brings a distinctive skillset of membership and trade association lobbying to the firm. Building and coordinating coalitions to effect strategic policy initiatives and a reputation for providing results driven advocacy are at the core of Kristen's work experience. Most recently Kristen served as Associate Vice President for Government Relations for the University of Nebraska where she led a team that advocated on behalf of the interests of the University at the capitol in Lincoln, in Washington, D.C., and across the state. This experience gave Kristen expertise in understanding the state and federal financial needs of higher education. In addition, this role required Kristen to work to support the success of Nebraska students, faculty, researchers, and constituents on a variety of policy issues impacting higher education at the state and national level. As the Executive Vice President for Legislation and Policy for the Nebraska Chamber of Commerce & Industry, she lobbied for four years at both the state and federal level and engaged in issues management with regulatory agencies on behalf of Nebraska businesses. During this time Kristen developed an expertise in taxation, business incentives, labor and employment law, as well as issues facing manufacturing. She also spent five and a half years as Vice President of Legal and Regulatory Affairs for the Nebraska Cattlemen where she lobbied and provided regulatory assistance on behalf of beef producers. This experience helped Kristen develop a deep understanding of the regulatory and legal world surrounding agriculture, natural resources, and the environment.
