In Memoriam: Dennis I. Williamson

It is with great sadness that we share the passing of Dennis I. Williamson, 75, of Anderson, Indiana, on October 13, 2026.

Dennis was a longtime friend and supporter of Indiana's convenience and petroleum industry. He served as a member of our Board of Directors when IFFA was known as the Indiana Petroleum Marketers and Convenience Store Association (IPCA). Dennis dedicated 30 years to Ricker Oil Company, retiring as General Manager. His leadership, friendship, and commitment to the industry will be fondly remembered by those who had the pleasure of knowing and working with him. He also proudly served in the United States Air Force and was actively involved in his community through the Knights of Columbus, American Legion, and Veterans of Foreign Wars.

We extend our heartfelt condolences to his wife, Nancy, his family, friends, and all who knew him.

Dennis will be remembered for his friendship, dedication, and the lasting contributions he made to our industry. He will be greatly missed.
