Louis John Alliano

It is with deep love and profound sadness that we share the passing of Louis John Alliano, a devoted husband, father and grandfather on March 24, 2026, surrounded by family at his home in Goodyear, AZ.

Lou had a deep love for New York, especially Brooklyn, where he spent his early years. His stories of working on Wall Street while going to school, watching the Brooklyn Dodgers, playing stickball with friends and spending time at Coney Island were stories he loved to share and became part of the fabric of his life. Though he later made California his home, those early experiences and memories stayed with him always.

Born December 13, 1938, in Brooklyn, New York, to the late Edward and Rae Alliano. He graduated from Midwood High School, joined the United States Army where he became an instructor. It was during this time that he was first introduced to computers that would shape the course of his life and career.

Lou built a pioneering career in the early computer industry, contributing to advancements at a time when technology was still in its infancy. He was involved in early supercomputing work at New York University’s Courant Institute, helping lay the groundwork for innovations that would shape the future. Throughout his career, he was known for his technical expertise, leadership and ability to build and guide high-performing teams.

A proud member of the Masonic fraternity, he became a Master Mason in 1964 and remained dedicated to its values for over 50 years, exemplifying integrity, loyalty and service.

Beyond his professional accomplishments, Lou will be remembered for the joy he brought to his family. A lifelong Chargers football fan with season tickets for over 50 years, he created lasting traditions by taking his family to games from the time his children were young. He instilled a love of football that continues, with his family planning to continue that in his honor.

He was also a true amusement park and roller coaster enthusiast at heart. Carrying cherished memories from his childhood in New York of Coney Island, Lou brought that same excitement and sense of wonder to his family even after moving to San Diego in 1974. He made it a family tradition to take his children, and later his grandchildren to Disneyland, Knott’s Berry Farm and Magic Mountain. He created countless memories filled with laughter, thrills and togetherness.

Lou loved the holidays, especially Christmas, a time when his generosity and joy shined brightly. He took time and pride in making the holidays magical, often going above and beyond to spoil those he loved, with gifts stacked high and a home filled with warmth and celebration.

A shared love of the Arts was a cornerstone of Lou and Annette’s life together. For more than 30 years, they were deeply involved with PowPAC, Poway’s Community Theatre, where he formed lasting friendships and made a meaningful impact. Lou generously dedicated countless hours working behind the scenes with a special knack for developing sound plots that brought productions to life. He earned multiple awards for his sound work, not only with PowPAC but several other theaters in the ACT family. In recognition for their unwavering dedication and service, Lou and Annette were honored with the PowPAC Lifetime Membership Award in 2023.

Lou is survived by his loving wife, Annette; children, Glenn and wife Heather Angoco Alliano; Suzanne and husband Peter Rossick; cherished grandchildren, Kaitlyn and husband Jesse Midgley, Kylie Downing, Connor Downing, Rae Alliano, Caden Grant, Jolie Grant, Nichole Lord; nephew Steven Alliano and wife Maura; nieces, Susan and husband Barry Richards, Christina and husband Jake Gleim; sister-in-law Michelle and husband Mark Schmidt; cousins and extended family members who will all miss him dearly.

Lou will always be remembered for his intelligence, quiet strength, and generosity. His legacy lives on in the lives he touched, the traditions he created and the love he gave so freely.

He will live forever in our hearts and will never be forgotten. May he rest in peace until we’re together again.
