Loving husband of Bette Gillis (née MacKenzie); devoted father of Laura (Brian) Seifert and Michael (Lauren) Gillis; cherished grandfather of Emma, John, Molly, Aiden, Claire, Gwendolyn, and Alasdair; beloved brother of Barb (Allen) Callstrom, the late Bea Conner, the late Jack (the late Joan) Gillis, the late Jerome "Dutch" (the late Judy) Gillis, the late Mary (the late Jerry) Smuda, and the late Terry (the late Rudy) Dorweiler.
Born in Faribault, Minnesota, he was the middle of seven children in a loving family that instilled in him a deep sense of pride in his roots, a strong work ethic, and an ambition that guided him throughout his life.
He attended South Dakota State University, where he earned his degree in pharmacy in 1961. Soon afterward, he proudly served his country in the U.S. Army as a captain while stationed in Korea. He began his professional career as a pharmacist with Osco and remained with the company for 38 years. Throughout his career, he served in many roles, demonstrating exceptional leadership and dedication, ultimately retiring as Vice President of Operations for Jewel-Osco in 1999.
Retirement began a new chapter of service and involvement. He devoted his time to the Barrington Historical Society, the South Barrington Zoning Commission, and the Glen landscape committee. His retirement found him doing some magnificent travel, and above all else cherishing the time he spent with his children, grandchildren, and countless nieces and nephews. Family was the center of his life always. He took great joy in celebrating their accomplishments, sharing their milestones, and creating lasting memories together.
He will be remembered for his unwavering loyalty, quick wit, wonderful sense of humor, love of music, endless curiosity, and genuine interest in meeting new people and learning new things. He approached every day with enthusiasm and gratitude, embracing every opportunity and experience that came his way.
He loved life and truly lived it to the fullest. His legacy of kindness, integrity, laughter, and love will continue to inspire all who were fortunate enough to know him.
