William Koloseike, 92, founder of the Bill Kay Auto Group, died March 6 at his home in Naperville.
A veteran of the U.S. Marine Corps, Mr. Koloseike graduated from Loyola University and took a dealership sales position. He opened his first dealership in 1969 and expanded to nine stores in Illinois and Arizona before retiring in 2002.
Known as a tough but generous man, Mr. Koloseike volunteered for the Family Focus organization; and he worked with the Ignation Volunteer Corps, a Jesuit ministry. He was instrumental in the construction of St Aloysius Gonzaga Secondary School in Nairobi, Kenya. It is the world’s first high school for AIDS orphans.
A supporter of many charities and nonprofits, including Leo High School, Mr. Koloseike was honored by the school as a distinguished alumnus and Man of the Year in 2009.
Mr. Koloseike was a longtime member of Naperville Country Club. He was an avid traveler and active in many sports including golfing, skiing, scuba diving and hunting. His sense of adventure led him to actions ranging from riding motorcycles to zip lining to traveling across the country via RV.
Survivors include sons Mark and William; daughters Judy and Nina; 10 grandchildren; and five great-grandchildren. Memorials appreciated to JDRF.
