Cornelio (Jun) Domingo Julian Jr., 55, passed away at 8:55 a.m. on September 5, 2025 in Fullerton, CA.

Jun was born on August 10, 1970 in Quezon City, Philippines to Cornelio Sr. and Lutgarda. As the youngest of three older brothers, he followed them to Southern California and graduated from DeVry University with a bachelor's degree in Computer Information Systems. He spent over 25 hardworking years specializing in integration architecture & solutions and proudly climbed to the role of a Technology Architecture Manager at Accenture.

On Christmas Eve, he married Joanne, a nurse who he fell in love with at first sight. On June 2, 2000; September 13, 2004; and November 10, 2012 respectively, he welcomed his children and his greatest joys: Jojo, Jesse, and Jacob. His family settled into Rancho Santa Margarita, CA in 2011 and happily lived there ever since.

Cornelio loved golfing and spent his last active moments doing so. He was an avid fan of the Dodgers, Lakers, and WWE. He enjoyed vacationing with his family around the US, and often planned them out by watching travel previews or tourist reviews to hype the family up. He proudly acquired a Tesla, which he happily drove everywhere. He cherished their weekend hotpot adventures. Throughout his time with us, he made sure to take plenty of photos in every moment, big or small.

Jun was an intelligent & knowledgeable man, constantly challenging himself to learn as much as he could without complaint. He led his loved ones through life with constant care. As a dedicated father & husband, he showed his love through providing acts of service—whether it was grabbing tea for Joanne in the morning, bringing Jacob to school and sports, or constantly reminding Jojo and Jesse of their adulthood to-do list. All who knew him will miss his delightful humor, comforting reliability, and authentic wisdom.

Jun was preceded in death by his parents and his eldest brother, Crizaldy (CJ). He is survived by his wife, his three children, two older brothers, Nathaniel and Jon, and a large & loving extended family.
