Barb graduated from St. Scholastica High School and went on to earn a degree in elementary education from DePaul University (where her father graduated from in 1938 and both of her children earned master's degrees). She started her career as a teacher at St. Henry's in Chicago and then moved to St. James in Arlington Heights where she taught 1st grade for 27.5 years.
Barb married James "Jim" O'Brien on June 12, 1971, at St. Henry's. She is survived by her devoted husband Jim, of Arlington Heights, two adoring children Kate (Dave) of Chicago and Kevin (Kim) of Rolling Meadows, two grandchildren she adored Sabrina and Adam Knoll, a loving sister-in-law Andrea (late John) Sullivan of Port Charlotte, FL, the Cowe Family of Worth, IL, cousins Susan Larkin and Nick Berenz, and many loyal and caring friends. Barb is preceded in death by her parents, John and Emma, brother John, cousin Brother Joachim A. Sullivan, OSA and nephew James Cowe.
Barb was best known for going anywhere, anytime to watch her grandchildren Sabrina and Adam in all their activities. She never missed a basketball game that Kevin played in, was a frequent fan at DePaul Athletics competitions and proofread Kate's dissertation way too many times. She loved outings with her "Retirees and Wannabees" and "Birthday" clubs and was the proud recipient of the Heart of the School award at St. James. She also was an avid precious moment collector and had over 100 figurines. Anytime she hung up the phone with her husband or children, the call ended with love you, kiss, cross, knock.
