Rodney Esser, fondly referred to as “Mr. Peanuts,” has been a cherished figure at Park Elementary School in Cross Plains since 1965. As the school was still under construction, Esser embarked on a journey that would span over six decades, starting when a carton of milk cost just 3 cents.
Throughout his extensive career, Esser has become a vital part of the school community, working with seven principals and impacting the lives of approximately 15,000 students. Known for his dedication, he has never taken a sick day and averages about 11,000 steps daily.
At the age of 86, Esser has decided to retire this summer, concluding his 61-year tenure. Reflecting on his career, Esser shared with WPR’s “Wisconsin Today.”, “I’m enjoying every minute of it…I know I’m going to miss it.”
The school district celebrated Esser’s retirement with a school-wide assembly on June 4. Students donned hats reminiscent of Esser’s iconic style, commemorated his accomplishments, and expressed gratitude through personalized notes. The assembly resonated with chants of “Mr. Peanuts, Mr. Peanuts, Mr. Peanuts!”

Esser’s journey with Park Elementary began when his family’s farm was sold to the district, leading to a job offer he hadn’t sought. Through the years, he has become a beloved figure, interacting with multiple generations of students.
Fourth grader Ethan Laabs noted, “When people think about it, he is a custodian; but he’s also like the king of Park School, like he owns it. And the fact that he shares it with everyone around him is just amazing.”
Esser’s impact extends beyond maintenance tasks. He supports students emotionally, creates playful environments, and contributes to local educational initiatives. This October, Esser plans to continue his involvement at the school as a volunteer, focusing on student support.
Esser emphasizes the importance of heartfelt connections, stating, “(My ways) come from the heart. If I can connect with the heart of a child and try to see the world through their eyes, that’s what made the connection with the kids and I.”
As Esser retires, school staff are preparing for the absence of a custodian who has been a constant presence. Nicole Kartman, a first-grade teacher who has worked with Esser for 17 years, highlighted his daily contributions, such as assisting young students with their outerwear.

Additionally, Esser has been a source of comfort for teachers, often adjusting room temperatures to their preferences. Kartman humorously remarked on this, saying, “I am going to have to learn to adjust better to temperature change.”
As the school community prepares for a new chapter, Esser’s legacy of kindness and service will undoubtedly leave a lasting impression.
