Thomas Glenn Hess Sr.

October 1, 1939 – February 9, 2026

Resident of San Jose, California

Thomas Hess, a devoted husband, father, grandfather, and man of faith, passed away peacefully on February 9, 2026, at the age of 86.

Tom was born on October 1, 1939, in Coalinga, California, to Glenn and Rose Hess. He was raised in Coalinga, and on September 25, 1959, he married Jean Miller, beginning a partnership centered on family, faith, and service. Together they raised their children: Stephanie, Thomas II, and Kristin.

In 1959, Tom joined the United States Air Force and served his country with honor. In 1965, Tom and Jean moved to San Jose, where they built their home and raised their family after Tom began his career with IBM. He spent his professional life in the emerging computer industry and retired from IBM in 2012 after 47 years of dedication.

Tom and Jean were founding members of St. Julie Billiart Catholic Parish, where Tom remained an active and faithful member throughout his life. He enjoyed his retirement serving as the go-to person for all things “Building & Grounds” at the parish.

Tom was preceded in death by his parents; his siblings; his wife, Jean; his infant son Jeffrey; his daughter Stephanie; and his grandson Trevor. While we feel his absence deeply, we also hold firm to the promise that sustained his life - that he now dwells with his Lord in heaven.

He is survived by his son Thomas (Renee), daughter Kristin, and six grandchildren: Jaclyn (Erik), Danielle (Mike), Michael, Jacob, Katie, and Emily, who will remember him for his quiet strength and devotion to faith and family.

A funeral Mass will be held at St. Julie Billiart Catholic Parish on April 10, 2026, at 11:00 a.m., with a celebration of life immediately following.

Interment will take place on Saturday, April 11, 2026, at Gate of Heaven Cemetery 22555 Cristo Rey Dr. Los Altos CA.
