Happy Mary Supple Day in Richfield! For the past 32 years, Mary Supple has molded the minds of generations of middle schoolers. She has taught both parents and their children. Today is her last day of teaching before retiring. Even though she has devoted the majority of her time to her students, she has also been active in various city organizations and commissions, eventually being elected Councilmember At-Large in 2018. At last night's city council meeting, the mayor declared June 9, 2021, to be Mary Supple Day. Read the proclamation in its entirety.
