Sharon Jean (Windorski) Ostroski, age 63, entered eternal life with our Lord Jesus Christ on Sunday, Sept. 11, after a 6-year battle with cancer, her devoted husband Jeff, son Jeff Jr., and daughter-in-law Carrie at her side.

Sharon was born to Philip and Florence Windorski in Milwaukee, WI on Oct. 30, 1958, the eldest of 4 children. She attended elementary school at Our Lady of Good Hope Catholic school. The Windorski family moved to Schofield, WI in 1972. Sharon attended D.C. Everest High School where she met her high school sweetheart and prom date, Jeff Ostroski, graduating in 1976. Jeff and Sharon were united in marriage on Aug. 5, 1978, at St. Therese Catholic Church, Rothschild, WI.

Sharon earned her associates degree with honors in accounting from NCTI in Wausau, WI in 1978. She started her accounting career at Marathon Electric from 1978 to 1980. She was later employed at Zimpro in Rothschild, WI until the family moved to De Pere, WI in 1990 for Jeff's promotion. She was immediately hired by US Paper Mills Corp. as an accountant clerk. While working there she earned her bachelor's degree, attending classes online at night while still supporting her family. Later she worked for Sonoco Products Co. (the same company, US Paper Mills Corp. was sold to Sonoco) as an office manager until her retirement in April 2019.

Sharon and her family traveled throughout the country visiting national and state parks. Some favorite destinations included Branson, MO, Yellowstone, WY, & Glacier National Park, among many others. Later in life she enjoyed going to Holcombe which became their private campground and watching her grand kids grow. She was such a good sport, Jeff's sidekick, and always participating in any and all of his adventures. She maintained a positive attitude, courage, and determination throughout her long battle with cancer that eventually took her from us too soon.

Sharon was a beloved and devoted wife, "truly a gift from God" as quoted by her husband. She was a loving mother to their son Jeff Jr., and a generous grandmother to Casey, Brendan, and Eric. She loved spending time with her grandsons and was constantly sewing patches on their worn pants or crocheting them blankets that they will cherish. She was also a talented cook and gardener. Over the years Jeff and Sharon cared for their twelve Shelties.

Sharon will be deeply missed by her husband of 44 years, Jeffrey Ostroski Sr, their son Jeffrey Jr. (Carrie), De Pere, WI; grandsons Casey, Brendan, and Eric, her father Philip, Schofield, WI; brother David (Toni) Windorski, Milwaukee, WI, sister Sandy George, Eagle River, WI; mother-in-law Joan Ostroski, Schofield, WI; brother-in-law Gregory Ostroski, Saline, MI; sister-in-law Julie Dassler (Max), Shawano, WI; brother-in-law Mark Moreno, Chesapeake, VA and numerous nieces and nephews.
