Mrs. Mary Costello

I have taught 4k, 2nd grade, and Kindergarten. While I enjoyed each one of these grade levels, Kindergarten remains my very favorite!

Each year I strive to create a safe and nurturing environment that encourages self discovery and growth. My hopes and dreams for each one of my students is to learn how to play and work together. 

My husband and I live in Hartland, have three grown daughters, and a golden retriever. We love the Lake Country area and feel lucky to call this home.
