Sean O'Reilly Obituary

O'Reilly, Sean

Sean O'Reilly, 43, of Chicago, transitioned peacefully and surrounded by love on February 26, 2021. Sean was born on January 6 in Oak Lawn to Francie (Hynes) and John O'Reilly both of Co. Mayo, Ireland. He grew up in Tinley Park. Sean was a 1996 graduate of Marian Catholic High School. He graduated Magna Cum Laude from Marquette University in 2000. Sean worked for the Federal Government for 20 years. He served as a Supervisory Officer within the Department of Homeland Security since 2011– working with a team whom he loved in a position he truly enjoyed. Sean was a man of deep faith. He served as a Eucharistic minister at Old St. Mary's, and previously served as a member of the parish council. Sean's most important role was being a good spouse to Shannon (Harrity), as well as, being a good father to their children, son Eamon and twin girls Madelyn and Vivian. Sean was an excellent dad, who loved playing soccer with Eamon and taking the girls on long walks. He was patient, loving, fun and lived life one day at a time. He was a kind man who touched so many lives. He was met in eternal life by his mother Frances. He is survived by his spouse and their three children; father John O'Reilly of Tinley Park; sister Deirdre of Mokena; sister Mary (Bienias) and Bryan of Tinley Park; friend Deric Jordan (Kimberly) of Chicago; two nieces and three nephews; and many loving in-laws in Kansas and Missouri. He leaves behind a host of aunts, uncles and cousins in Ireland and in the States, family of his heart and countless friends. Sean, as he did most weeks, would want to thank and acknowledge those working in the Cancer Center and all of his care team at Northwestern. The kindness, stories, care and friendship given to him over the years meant so much to him. Peace.
