Bonnie Halvorsen, Campus Farm Partnerships Manager

Bonnie officially joined the Office of Sustainability as the Campus Farm Partnership Manager in 2016, although she has collaborated with the Office on sustainable food systems projects for years prior. Currently she is directing a complex partnership between UWM, Milwaukee Public Schools, Milwaukee Area Technical College, Cream City Conservation Corps, Institute of Urban Agriculture & Nutrition, Boys & Girls Clubs of Milwaukee, Groundwork Milwaukee, Milwaukee County Parks Department, and American Red Cross.

Bonnie is a card-carrying foodie and gardener. She believes not only in the therapeutic aspects of eating good food, but also in growing and sharing good food. The Campus Farm Partnership is the fourth start-up project she has managed at UW-Milwaukee. Other start-ups include the Institute for Urban Agriculture & Nutrition, the School of Freshwater Science and the Zilber School of Public Health, for which she was recognized with a 2009 Women of Influence Award.

, Surplus Manager

Andrew joined the Office of Sustainability in November of 2016 as manager of the Surplus program.

Adrian Robar – Truck Operator

Adrian joined the Office of Sustainability in 2019 as a truck operator after working previously in manufacturing for 20 years as a heavy equipment and forklift operator. He started working at the office because of how dangerous his job in manufacturing was and because he wanted to work for a company that not only was better for him, but also helped the people around him. His job as the OOS includes collecting recycling, putting it into the right receptacles, having it taken away, and more. Adrian hopes that people will see recycling more as a norm in the future as it has made a big impact on him since joining the office.
