Over the past two months, several teachers and administrators in the Pella School District have been granted early retirement. This week it was announced that one more teacher will be added to the list, 6th grade math teacher Gifford Graham. Graham has been with the school district for 32 years and Superintendent Mark Wittmer says that he will be greatly missed. Wittmer adds that Graham provides a lot of experience and is great at what he does. Graham is expected to retire at the end of the school year.
