Mr. Omar McMillan

I could not have chosen a better profession to enter.  18 years of teaching has been a great and rewarding experience for me.  I started my career in Minneapolis Public Schools at Armatage Community School. In 2003, Richfield brought me aboard and I have been teaching at RSTEM(RIS) ever since.  As a member of the community, as a resident, parent, teacher and a coach, I am super proud and honored to be a SPARTAN/SPARK.

Mr. Chris Olson

This is my 29th year teaching in the Richfield School District. Establishing positive relationships with children, providing a stimulating learning environment, and helping kids grow academically is my goal and life’s purpose.

I grew up in Minneapolis and graduated from Augsburg College. Later, I received my Master’s Degree in Elementary Education from the University of Minnesota. In addition to fourth grade, I have taught kindergarten, third grade and second grade. My wife works in the Eagan schools as a special education teacher. I have three children (15, 14, and 10) who use me as their unpaid Uber driver when I return home each night. I spend most of my free time watching my kids’ sporting events around the metro area.

Something interesting about me is the classroom I teach in is the same classroom I went to as a 5th Grader with one of my all time favorite teachers, Nel Swanson.
