Colleen A. O'Brien

Colleen (Ventetuolo) O'Brien, 72, of Plainfield, passed away Tuesday, March 17, 2026, peacefully at William W. Backus Hospital, surrounded by her children and husband. She was the loving wife of Patrick O'Brien. Born in Providence, RI, she was the daughter of the late John and Barbara (McMehan) Ventetuolo.

Mrs. O'Brien was raised in Chepachet, Rhode Island, alongside her brothers. She attended and graduated from Ponaganset High School. She went on to marry her husband, Patrick. They spent 46 years together raising their 4 children and enjoying time together as a family. Colleen loved gardening, cooking, nature, camping, and water skiing (even backwards sometimes) on the back of her father John's boat. But most importantly, her favorite times were spent around a table with lots of good food and her loved ones. Everyone that knew her would describe her as a regular fireball. She was full of personality, love, and fun times.

In addition to her husband, Patrick, Colleen is survived by her children, David O'Brien of Eastford, CT, Jeremiah O'Brien of Rochester, NH, and Colleen Middleton of Norton, MA; along with her 9 grandchildren, Nicholas O'Brien, Leah Hooker, MaKayla O'Brien, Angelina Middleton, Isaac Middleton, Graycee O'Brien, Matthew Middleton, Jeremiah Middleton, and Abigail Middleton. She is also survived by her two great grandchildren, Ivory and Damian Hooker. She is predeceased by her son, Sean Patrick O'Brien.
