Rex Gerald (Jerry) Raiza, born March 4, 1938, passed away Friday September, 17th, 2021 at the age of 83 after complications of aortic aneurysm repair surgery. Rex was born in El Paso to Elizabeth (Libby) and John Rex Raiza, raised in the small town of Woodson, and relocated to Dallas, Texas in 1958. A true Texan through and through. Rex is preceded in death by his wife of 60 years, Maebelle, in September, 2019, and son, Gary, in July of 2020. There is much comfort imagining them together! He is survived by his daughters Janna Fjerstad and Rebecca Raiza. Son in law, Paul Fjerstad , daughter in law, Tracy Holden-Raiza and four granddaughters who considered him the greatest Grandaddy ever: Lauren Raiza, Lena, Thea and Mia Fjerstad. Rex had a long, successful career as an HVAC mechanical engineer with Blum Consulting Engineers, Inc, in Dallas. Starting March 1, 1960, after his studies at Texas Tech, in Lubbock, he never retired. At 83, he remained a central figure in the company and an expert on special projects. He was a true trailblazer and highly respected in his business. He was known as Rex professionally, but family and friends called him Jerry. He loved his family, animals, fixing things, country music of his era like Bob Wills, sharing stories about his life in West Texas and telling a good joke. His soft, sweet, modest demeanor was a true gem and a gift to the world. He will be forever missed and remembered with love. A celebration of life will be on Sunday, October 10th, 2pm at Royal Lane Baptist Church, with a reception following.
