John Kenneth Kloster III

John Kenneth Kloster III, 71, passed away June 26, 2023, after a courageous battle with lung cancer.

He was preceded in death by his parents, John K. "Jack" and Maryellyn.

He is survived by his partner, Kitty Cayo; his children, John (Kelly) Kloster and Amanda (Will) Campbell; his grandchildren, Cameron, Charlie, Kendall, Willow and Charlotte; his sister, Susan Kloster; and his stepson, Durk Way.

He was born in Hinsdale and grew up in Downers Grove, graduating from Downers Grove North in 1969. He graduated from William and Mary in 1973. He was a proud member of Lambda Chi Alpha fraternity, where he met many lifelong friends. John had a long career in the travel industry and enjoyed traveling the world.

He had a great mind and the ability to do insane calculations in his head, solve crosswords in record time and intelligently discuss all of the questions of the world. Those who knew him will miss his endless stories, great taste in music, sage advice, guidance and thought-provoking questions. Mostly they will miss the way he made them all feel loved in their own way.

Visitation is from 3 to 5 p.m. Tuesday, Aug. 22, at Sullivan Funeral Home, 60 S. Grant St., Hinsdale.

A chapel service will be held at 5 p.m.

Internment is private.
