Jason Robert Brennan, born February 12, 1972 in Springfield, Illinois, passed away on December 31, 2025, in Burbank, California at the age of 53. He leaves behind a legacy of creativity, humor, and deep compassion.
Jason spent his formative years in Ohio, attending middle and high school in the Centerville area. It was during his early teenage years that he discovered what would become one of the great loves of his life: the guitar. Music remained a constant thread throughout his life, a source of joy, expression, and connection.
He built a distinguished career in sound editing/engineering for motion pictures and television, a field that perfectly blended his technical skill with his lifelong love of film and storytelling. His work behind the scenes helped bring countless projects to life, and he took great pride in contributing to an art form he cherished. Among the projects on his credit list were “Tracker,” “Avatar: The Last Airbender” and “How to Get Away With Murder.”
Those who knew Jason will remember his sharp wit, his generous laugh, and his ability to find humor in almost any situation. He loved movies, music, and history, and he could talk about all three with an enthusiasm that made conversations with him unforgettable.
Jason also had a profound love for animals, especially his dogs. His companions Frank and Teddy Van Halen (“Teddy”) were not just pets but family, and they brought him immense comfort and joy.
He was preceded in death by his father Patrick Brennan and mother Elizabeth “Buff ” Brennan. He is survived by his aunt Kathleen Cordero. Jason was a proud Army veteran.
Jason’s life was marked by curiosity, creativity, and kindness. He will be deeply missed by the family, friends, colleagues, and loved ones who were fortunate enough to share in his world.
Thanks to whoever put this out. I am a close and longtime friend of Jason for over 30 years. I feared that he had passed. He did not share with me that he was ill until the last time we communicated via text. It looks like this was 4 days before he passed. I am not sure why he chose not to tell me. I tried all the ways I could think of to find out what was going on. We first met while both working at Nordstrom’s in downtown Seattle and both of us loved creating music which started some of my fondest memories of us struggling and learning to record our songs, first with a 4 track cassette recorder, then a 8 track reel to reel and eventually with a PC. Jason had a room set up at the house he shared with his friend Andy, up on Queen Anne hill in Seattle. Many laughs and break through’s there. I even brought my Daughter over there many times while we
recorded. I am going to miss our conversations and emails and texts that we had over all these years. If anyone has any info on where the hard drives etc. might be with our recordings and photos on them, I would be grateful. Those memories are priceless to me. I know he did not have much family. I am heartbroken by this news. Jason was a great guy with a great sense of humor and very caring and generous. He definitely loved what he did.
