Hello! I'm Mary Hamstra and I have taught 2nd grade for many years. I graduated from Morningside College and began my teaching career in 1980. My husband, Lyle, and I live in Sioux City. We have 3 grown children. Some things we enjoy in our spare time are spending time with our grandchildren, watching sports, exercising, golfing, and cooking. I really enjoy working with the staff, students, and families here at Dakota Valley.
