A much-loved father, brother, grandfather, and friend, David (Dave) Jeffrey Schleis, 66, passed away the evening of August 2, 2015 at Langlade Hospital in Antigo with family present. He had bravely confronted and fought brain cancer since December 2014.

Dave is survived by his son, Jeffrey (Lindsay) Schleis; his daughter, Kelly Schleis; his sisters, Gale (Tom) Whitener and Donna (Skip) Evans; his brother, Larry (Kim) Schleis; his former wife of 23 years, Catherine; his grandchildren, Cole, Stella, and Isobel Schleis (children of Jeff and Lindsay Schleis); and his nieces and nephews.

He was preceded in death by his twin brother, Steven Schleis, and his mother and father, Daniel and Katheryn (Zirkle) Schleis.

Dave was born on July 17, 1949 in Antigo, WI and worked at his family’s feed mill when he was young. He graduated from Antigo High School and later received his Bachelor of Science degree from the University of Wisconsin Oshkosh. Dave began a successful career in pharmaceutical sales for Purdue Frederick and later retired from food service sales.

Our dad loved riding motorcycles and living an adventurous lifestyle. Throughout his life he enjoyed numerous hobbies such as water skiing, downhill skiing, golfing, fishing, and camping. He also liked hunting with his son, his brother Larry, and close friends by his side. He held many accomplishments such as qualifying as a Pro-Marksman in the National Rifle Association and earning his Solo Pilot certification. One of his many joys was having his Bareboat Charter license and sailing the Great Lakes with his friends. He was a great helmsman!

Dave enjoyed a relaxing, early retirement living on Post Lake spending much of his time boating and fishing at his “SPA”. He treasured spending time with his family, took great pride in his children, and relationships maintained with many close friends. He loved his dream trip to Costa Rica with his children in April and recently had a wonderful celebration of life with his dear friends and family for his 66th birthday held at his lake home. He will always be remembered for his unique and clever sense of humor, his strong will, and passions for nature and wildlife.

The family strongly encourages online condolences and welcomes friends and family to view the many pictures posted of special memories of Dave’s life. Per our father’s request, there will not be a memorial service.
