James Eugene O'Brien, 81 of California, MD passed away peacefully on Wednesday, August 13th, at Hospice House of St. Mary's, surrounded by his loving family.

Jim was born in Philadelphia, PA as the youngest of four children to Irish immigrants, John and Sarah Cecilia O'Brien. He attended St. Joseph's Preparatory and went on to earn an electrical engineering degree from Drexel University.
