Welcome to the 2018-2019 school year at Riverdale High School. My name is Mike Walker and I am looking forward to teaching your child about Economics and Sociology. This marks my 25th year in education and 4th at Riverdale. One important resource that will benefit your child is communicating with me. Feel free to email me anytime concerning your child's progress. The link at the bottom will take you to iNow to check progress and grades.
