Emil Costantino

February 12, 1940 - December 30, 2025

Emil John Costantino Jr. of Temple City passed away peacefully after a long battle with kidney disease.

Emil (Sonny) born in Glendale, California, was the son of Emil Costantino Sr. and Zita Marie Costantino.

He was a cherished husband of over sixty years to Mary Annette (Hamner) Costantino. He leaves behind a legacy of three sons: Brian (Michelle), Bruce, and Andrew (Julie), along with his six grandchildren, Jacob, Sarah, Kimberly, Anthony, Dominic, and Marco. He is remembered by his siblings, James (Marilyn) Costantino, Arleen (Bud) Nelson, and Richard (Peggy) Costantino.

Emil spent his entire career as the owner and operator of Induction Heat Treating, where he was celebrated for his dependability, dedication, and passion for his work. His family's ties to the heat-treating industry were strong, with his father, Emil Sr., who began the heat-treating business during WWII influencing Emil's career and work ethic. From 1963 to 1965, Emil proudly served in the United States Army.

Over the years, Emil discovered simple happiness in the things he cherished most: riding motorcycles, barbecuing, showering his dogs with love and care, and tinkering with his prized T-bird.

A funeral service will be held at Saint Luke's Church on Friday, January 30, 2026, at 10:30 a.m. The service will be held at 5605 Cloverly Ave, Temple City, CA with a reception to follow at Temple City Womens Club. 9704 Woodruff Avenue Temple City, CA.

In lieu of flowers, a donation to the San Gabriel Valley Humane Society (https://www.sgvhumane.org/memorial-honor-donations/) in Emil's memory would be a fitting tribute honoring his love of animals.
