Keith was born in Kansas City, Kansas and was baptized at Blessed Sacrament Catholic Church. He went to Blessed Sacrament elementary school, and then attended Saint Agnes when the family moved to Fairway, KS in 1970.
He graduated from Bishop Miege High School in 1975 and from Kansas State University in 1979. He worked in distribution at a number of different companies throughout his career, most often in a managerial role. Keith was a long time member of St. Elizabeth Catholic church, where he served the parish in his role as an usher at masses.
He was a thoughtful, kind man who was very generous to others. He maintained a vegetable garden in his back yard, with the main purpose of sharing his bounty with co-workers and neighbors. Keith enjoyed gardening, woodworking and finding treasures at garage sales.
He is survived by his brothers Eric Martincich (Mary Jo) and Carl Martincich (Diane), his sister Diane Schwartz (Bill), 8 nieces, 1 nephew, and some great nieces and nephews too.
