He was the beloved husband of 66 years to his high school sweetheart, Keville Parker, and the devoted father of David Parker (spouse Shelley Parker).

A graduate of Bellarmine College Preparatory in San Jose, California, Jack briefly served in the U.S. Army from 1956 to 1957 before beginning a long and successful career as a business owner in the print industry until his retirement. He was an active member of both the Pleasanton North Rotary and the Sons In Retirement (SIRS), where he built lifelong friendships and gave generously of his time and good humor.
