Ms. Cassi
My name is Cassi Williston. I have been teaching for the past 31 years. The past 19 years I have been teaching in District 200 in the Early Childhood Department. My husband and I are both Wheaton North graduates. We have two daughters that also graduated from Wheaton North. Our oldest attends Cherubim- a Developmental Day Program for adults with disabilities and our youngest is in her final year of Grad School at Carroll University.
I enjoy reading, kayaking and spending time with family and friends. This summer we welcomed Stein, a quarintine puppy to our family.
