Passed away on January 25, 2019, age 63, at Aurora, West Allis Medical Center, after a short illness.  

Mark is survived by his loving wife Sandra, his father Arthur Olen, Sr. of Cudahy, his brother Arthur (Jodi) Olen, Jr. of Appleton, and his sister Susan (James) Cowel of Oak Creek. Beloved father of Marie Davis of Waukesha and  Matthew (Tammy) Olen, Sr. of Milwaukee and their children, Storm, Matthew, Jr., and Austin. Further loved by other relatives and friends. 

 Mark grew up in the Cudahy area and joined the US Army after high school, serving in Vietnam as a MP. He was proud of the time he spent serving his country.  

 Mark married Sandra Lisowski on September 28, 2008. The love and support they shared for one another was a highlight in his life.

 Cheering on The Green Bay Packers, Wisconsin Badgers, and the Milwaukee Brewers brought great joy and fun to Mark’s days. In his younger, healthier years he enjoyed going hunting and fishing with his friends and later in life enjoyed sharing the stories.

Sandra would like to express her hearth felt thank you and appreciation to the staff at St. Joseph Hospital (Milwaukee) and the Aurora West Allis Medical Center for their service and support during the difficult time of Mark’s illness.

Private services held on Monday, January 28, 2019, in Milwaukee.  A burial with Military Honors will be held at Southern Wisconsin Veteran Memorial Cemetery, Union Grove, Wisconsin at a later date.
