On Tuesday, October 1st, 2019, Thomas William O'Brien Sr., loving husband and father of four children, passed away at the age of 77.

Thomas retired after 40 years of working at the Mobil Oil Refinery Plant in Chicago, IL, starting out as a maintenance tech, working on the boilers to maintain operations for Mobil Oil.  He also served over 40 years on the Crestwood Fire Department, retiring as an Assistant Chief.

Thomas is survived by his loving spouse of 58 years, Sandra O'Brien, nee Okon.  Thomas was the father of Thomas William Jr., Patrick Michael (Cindy, nee Kunkes), Joseph Alan (Tracey, nee Cowan),  and Kathryn (Jerry) Lannom.  Dear grandfather of 6:  Justin (Monica), Hayley (Nathan) Becker, Josephine (Taylor) Broderick, Kaitlynn, Kayla, and Destini.  Loving great-grandfather of 3: Nadia, Evelyn, and Lincoln.

Thomas was a stern, hard-working, and caring man who put his family above everything else.  His love for his wife and children, then later his grandchildren and great-grandchildren were easily expressed through everything he did.  No matter what was happening in life, Tom always put his family unconditionally first.  He had a great sense of humor and loved to be around his kids.  He laughed always, loved watching the Chicago Bears, and brought every room to life when he showed up.  He had an infectious smile and a compassionate spirit that radiated from his very essence.

A Memorial Service will be held on Saturday, October 5, 2019 from 2 P.M. until 6 P.M. at the Becvar & Son Funeral Home, 5539 W. 127th Street, Crestwood.  (708) 824-9000 or www.becvarfuneralhome.com
