Gregory Mark Koshak, age 63, of Larsen, Wisconsin, joined his heavenly Father on Friday, July 7, 2023. He was born on November 27, 1959, in Rhinelander, WI to Ray and Lois (Cook) Koshak.

Greg graduated from Rhinelander High School in 1978. He then went to UW-Stevens Point where he met his wife, Wanda (Doenier). He graduated in 1983 with a BS in Paper Science and a minor in Chemistry, started at Kimberly-Clark and moved to Neenah, WI. He did go back to school and get his Masters in Career and Technical Education from UW-Stout in 2003.

Greg's love for animals was reflected in the constant presence of a family dog and even a cat (Sandi). Roxy and Rudy miss him and his schedule of treats. Roxy made it her job to keep track of Dad and would sometimes remind him of that very important treat schedule.

Greg is survived by his loving wife of 40 years, Wanda (Doenier), three children: Cara of West Bend, Alexandria (Deon) Birschbach of Menasha, Nathan (Jasmine) Koshak of Appleton; three grandchildren, and his brothers: Evan (Judy) Koshak, Rodney Koshak, Denis (Diane) Koshak.

He was preceded in death by his parents; and sister, Sue Bramann.
