Calvary Cemetery.

Willie was born on January 11, 1966, in Dubuque, Iowa, son of Donald and Patricia (Hentges) Koster.

Willie attended school in Dubuque, and after that became the primary care taker for his mom.  After she passed away, Willie was employed at Eagle Window and Door, Steel Warehousing for several years and lastly for Liqui-Green.  He also helped his cousin, Donny Hentges, driving on the bread route, along with several other “side-hustles”.  He was united in marriage to Kimberly Doser on February 6, 1996, in Las Vegas, Nevada.  They were together for several years and had 2 beautiful daughters before taking separate paths in life.  Willie was a Harley Davidson enthusiast and loved getting out on the open road riding his bike.  He enjoyed being outside fishing and golfing as well as shooting pool in league for several years.  Willie was a die hard Hawkeyes fan, and everyone knew that if a gift needed to be purchased anything Hawkeye or Harley would be greatly appreciated.  Willie always put his family and friends first in his life.  He regularly got the family together for dinners and fun activities, making sure to send out his famous “chop-chop” reminder so no one would be tardy to the party.  Willie was adventurous and lived life to the fullest, something he always encouraged those around him to do.  He had the best sense of humor and was a great prankster, always providing a good laugh.  He was deeply loved and will be missed by everyone who knew him.
