William Amel “Bill” Oberg, a fixture of the Centralia, Illinois, community known for his resilient spirit and infectious sense of humor, passed away on Thursday, April 2, 2026. He was 75 years old.
Oberg died peacefully at his home in Centralia, leaving behind a legacy defined by a diverse professional journey and a deep devotion to his family. Those who knew him describe a man who viewed life through a lens of earthy wisdom, often attributing his perspective to a self-described degree from the “school of hard knocks.”
A lifelong learner of the practical and the profound, Oberg was recognized by friends and colleagues as a man of the people who never met a stranger. His presence was often marked by an “off the wall” humor that could shift the energy of a room, paired with a consistent readiness to assist anyone in demand.
Beyond his personality, Oberg was a passionate enthusiast of the blues. He spent much of his leisure time attending concerts and sharing his love for the genre with his children and grandchildren, viewing music as a vital connection to those he loved.
A Professional Journey Across Southern Illinois
Born on March 5, 1951, in Ann Arbor, Michigan, to Lloyd and Norma (Ashby) Oberg, Bill Oberg eventually made Southern Illinois his home. His professional life was characterized by versatility, spanning industrial work, specialized tributes, and entrepreneurship.
Oberg’s career included significant tenures at World Color Press in Salem, Illinois, and at Hi-Shots/Memorial Tributes. He later transitioned into small-business ownership, operating Bo’s Sales Center in Centralia, where he became a known figure in the local business community. In his final professional chapter, he contributed his skills to Prairie Built Buildings in Mt. Vernon, Illinois.
This trajectory from corporate roles to independent business ownership mirrored his personal philosophy of resilience. By navigating various vocations, Oberg embodied the grit and adaptability he frequently championed in his conversations with others.
Family and Personal Legacy
Oberg’s personal life was anchored by his marriage to Tonia Ganswind in 1997. Together, they built a family that spans several states, reflecting the broad reach of his influence.
He is survived by his wife, Tonia Oberg of Centralia, and three children: Shana Oberg of Toledo, Ohio; Bill Oberg, Jr. Of Milwaukee, Wisconsin; and Taylor Oberg of St. Louis, Missouri. He too leaves behind his step-daughter, Stephanie Anderson of Highland, Illinois.
As a grandfather, Oberg took immense pride in Audrey Oberg and Brody Oberg of St. Louis, Missouri, as well as Brendan Oberg of Albuquerque, New Mexico.
His passing follows the loss of several close family members, including his parents, his sister Jackie Gagnon and her husband Ray of Wayne, Michigan, his brother Gerald “Buck” Jannett of Taylor, Michigan, and his nephew Scott Gagnon of Wayne, Michigan.
