Reilly Mills

Administrative Assistant

Reilly Mills

Reilly Mills lives in Maple Grove with her parents and 2 adorable dogs, Dexter and Sabina. After 2 years at UW-Eau Claire, Reilly decided to take a break from school to explore some other options in 2018 and began working for Kathy Petersen as a nanny. As the president of Opus Music Academy, Kathy Petersen quickly identified additional untapped talents in Reilly and hired her on as an administrative assistant in February of 2019.

When she’s not working, Reilly plays on a co-ed soccer team and spends time working on volunteer projects that support children in need; specifically those in foster care and those fighting cancer. She’s also addicted to Sudoku. Reilly’s dream is to eventually move to a warmer climate and away from Minnesota winters. It’s a goal Kathy Petersen supports but is isn’t looking forward to when the day comes.
