I am very excited to be teaching 6th grade math.  This will be my fifth year at Mahtomedi teaching 6th grade math.  I received my bachelors in education from The University of Wisconsin River Falls.  I live in Forest Lake with my husband Nathan, son Leo and daughter Lennon.  We have two very energetic dogs, Annie who is a chocolate lab, and Noodle who is a golden retriever.  In my free time I love to take my dogs to state parks, go camping, read great books and spend time with my family.

Feel free to contact me, email will be the best and easiest way to get ahold of me.
