David T. O'Brien passed away on December 28, 2022, too early at 67 years of age. He was preceded in death by his parents Robert T. O'Brien and Davida O'Brien. He retired as a Highway Operations Technician for the Arizona Department of Transportation. He was a lifelong Arizonan.

Dave (D.T. to his family) is survived by the love of his life; Rose Perry, with whom he has been inseparable since first meeting over 38 years ago. He is also survived by his sisters Dinneen Pollock and Dayna Nicholas as well as his nephew Dustin Nicholas. His family feels lucky to have had such a wonderful loving and caring brother and uncle.

Growing up in Arizona, he loved to spend time in the outdoors; fishing and riding his dirt bike. He also enjoyed playing golf and pool with Rose.

His big heart touched the lives of everyone he knew. Much of his life was devoted to helping others. He was a teacher and mentor to many around him.

There will be only a small private gathering to celebrate his life.
