Rebecca A. "Becky" Klostermann (née Priestley), age 77, of Breese, passed away on March 5, 2026, at her home in Highland. Born on October 28, 1948, in Red Bud, Illinois, she was the daughter of the late Harry and Elizabeth (née Sieberg) Priestley.

A dedicated reading teacher, Becky retired from Hinchcliffe Elementary School in O'Fallon after many years in education.
