BERRIEN SPRINGS — If there’s one constant in Bonnie Chadderdon’s four-decade career, it’s that she loves teaching and she loves reaching out to help students in whatever way she can.

During her 40-plus years with the Berrien Springs school district, she has taught migrant children, taught English as a Second Language (ESL) at Mars Elementary School and then English and Spanish at Berrien Springs High School. And, over the last decade, she has created and directed the Afterschool Rocks program at the high school.
