Gary J. Bosar

November 17, 1950 ~ March 16, 2021 (age 70)


Gary Joseph Bosar, age 70, Green Bay, passed away unexpectedly on Tuesday, March 16th, 2021. He was born on November 17, 1950 in Green Bay, the first child to Earl and Therese “Terry” (Holewinski) Bosar.

He met his wife Sheila at the Prom in De Pere on August 8, 1969. On August 19th, 1972, they were married at Assumption BVM Catholic Church in Pulaski, WI.

Gary will always be remembered for balancing his selfless work ethic with a jovial appreciation for life.  He provided his wife and children with both security and adventure.  He matched his considerable accomplishments with humility and generosity, always willing to volunteer his time, and never losing his appreciation for life’s simplest gifts.  All it took was unexpected spot of good weather or a cheap meal to bring a smile to his face and that joy was contagious. 

He was a beloved husband and father and loved nothing more than spending time with his family.  He enjoyed traveling and looked forward to family trips.  Upon his retirement in 2019, he took many trips to Door County, California, New Mexico, Michigan, and Florida.   When Gary wasn’t traveling or helping his family with projects you would find him working outside in the yard.  Gary was an avid gardener and took great pride in all of his flowers, especially his roses.  Gary became a grandpa for the first time in February 2021 and couldn’t wait to spend time with his grandson and was looking forward to watching him grow up.

Gary graduated Green Bay West High School in 1969,  and obtained his Bachelor of Science degree in Civil Engineering from Purdue University in 1973. He was a licensed Professional Engineer in Wisconsin and Ohio. Gary spent his professional career at Scott Paper Corp in Everett, WA, Philadelphia, PA, Box Hill, Australia, and San Jose, Costa Rica; and at Baisch Engineering in Kaukauna, WI, where he served until his retirement in 2019.

Gary is survived by his two sons, Justin W Bosar, 40, of San Francisco, CA, his fiancée Mei Kuen Liu and Trevor G. Bosar, 35, of Little Chute, WI, his wife Melanie, and their son Lucas C Bosar; siblings Curtiss (Patti) Bosar, Gail Rudnick, and Brian (Denise) Bosar; mother-in-law Elizabeth (Betty) O’Connor; in laws – Kelley O’Connor, Erin (O’Connor) Tisch and husband Ron, Megan O’Connor Heiman and husband Tom, Maureen O’Connor and husband Scott Liebl, Shawn O’Connor and fiancée Teri Miller, Brian O’Connor and wife Melissa, along with several nieces, nephews, and cousins, and special friend Cindy Vaness.

He was preceded in death by his wife Sheila, parents Earl & Therese (Terry) Bosar, father-in-law Lyle O’Connor, and brother-in-law David Rudnick.
