John Wilson O’Brien

May 09, 1958 ‒ August 05, 2020

Marengo, Ohio

John Wilson O’Brien, age 62, passed away way too young at OSU Medical Center in Columbus on Wednesday, August 5, 2020, surrounded by his wife and children.

John was retired from the USPS with over 30 years of service.  He had many lifelong friends from his time at the Post Office, working at Twin Rivers Drive, Georgesville Road, and The City Gate Plant.

John was born on May 9, 1958, in Steubenville, Ohio, to Wilson O’Brien and Lucille M. (Gescheider) O’Brien, both of whom preceded him in death.  He is survived by his loving wife of over 35 years, Cynthia Sue (Collmar) O’Brien; a daughter, Jessica Davis (Ryan Bardar) of Sunbury; two sons, Cory O’Brien of Marengo and Timothy (Kristi) O’Brien of Galena; three grandchildren, Dylan Seward, Teagan Bryant, and Benson O’Brien; two brothers, Michael (Karen) O’Brien of Sunbury and Patrick (Connie) O’Brien of Wintersville; and several nephews and nieces that lovingly knew his as “Uncle Big John.”

In addition to his parents, John was preceded in death by his grandparents, William L. “Money” and Leona O’Brien and Kenneth and Margaret Collmar; and John’s beloved brother, David Oller.

John was an enthusiast of his Harley Davidson motorcycle and learned to ride his bike on the ultimate trip to Sturgis with lifelong friends.  His children and grandchildren were his life and he was always on the sidelines watching basketball, baseball, football, softball, and gymnastics to support them.   John was also an avid coin collector and if you knew John, you knew he could quote any date in history when asked.  Cindy always wanted him to audition for Jeopardy.  John loved to travel and was able to visit 42 National Parks with his wife.

Memorial contributions can be made in John’s name to Lifecare Alliance of Ohio.  His corneas will live on helping a stranger regain their sight.

  • Please let me extend my deepest sympathy to John’s family. I attended and graduated high school with “OB” (as we called him back then). He was one of the good guys. A gentle giant. And always had an ornery way about him that made him so likeable and funny. Ironically, I too just retired from the USPS (38+ yrs) in our hometown. May God shed His mercy on his soul and let His perpetual light shine upon him. And may you, his family, find solace in the love and memories that you have shared with John help you get through these most difficult days ahead. God bless you all.

  • My deepest sympathy to the family of OB. I also graduated with him and remember his humor with a smile. RIP to a fellow postal worker,

  • Cindy,

    Sorry for your loss. John was in my wedding and we shared apartment in Columbus in 1981. Went to Grade School and High School together. I always wondered what became of him. Sounds like he shared a happy and fulfilling life with you.
    Praying for John, you and your family.

  • To the O’Brien family –
    I just learned from PJ of OB’s passing. We all went to St. Peter School together, and OB was a friend and classmate those years. I was deeply saddened to learn of his passing. His obit is right; he is gone way too early. The last I spoke with him was at Big Walnut High School during Jessica’s game there. He was larger than life, and full of life. The world is worse in his passing, but so much better for his being here. May Christ’s peace sustain you and comfort you all.
