Ms. Cassi

 My name is Cassi Williston.  I have been teaching for the past 30 years.  The last 18 years I have been in District 200 in the Early Childhood Department.  My husband and I are both Wheaton North graduates. Both our daughters also graduated from Wheaton North.  Our oldest attends Cherubim- a Developmental Day Program for adults with disabilities and our youngest is in Grad School at Carroll University. 
I enjoy reading, kayaking, photography and spending time with family and friends.
