Richard Cody
School Prinicpal
Greetings in our Savior's name! My name is Richard (Rick) E. Cody. I have been a principal and teacher for the last 31 years. I have served at St. John's, Lomira (5 years), Christ, West Salem (Christ-St. John's Lutheran School - 11 years), and St. John's, Juneau (15 years). I am enrolled in the graduate program at Martin Luther College, New Ulm, MN to get a Masters in Educational Leadership.
I grew up in Lake Mills, WI. I attended St. Paul's Lutheran Church and School in Lake Mills. For high school, I attended Lakeside Lutheran High School in Lake Mills. Dr. Martin Luther College in New Ulm, MN is where I spent four years and studied to become a teacher. In my school years, I enjoyed playing football, basketball, and baseball.
My wife, Lisa (nee Bonnell) and I were married June 8, 1996. My wife and I have five children that we are very blessed to have and love very much! Lisa and I became grandparents to a baby girl this summer (July 4, 2021). We are very excited for this next chapter! My wife and I enjoy spending time with our children (Sydney, Kylie, Maggie, Micah, and Grace), family, and friends. I enjoy the outdoors when I have the opportunity and treasure the moments when I can hunt and fish.
Welcome to St. John's and I would love to talk to you about Christian education here at St. John's and available through Luther Preparatory School (Watertown) and Lakeside Lutheran High School (Lake Mills).
