POYNETTE/ARLINGTON -- On Tuesday, October 21st, 2025, our family was devastated by the sudden loss of a son, life partner, father, brother, nephew, cousin, and friend, in a tragic car accident.
Gregory Dellmann was born on April 19th, 1978, in West Bend, WI, to Kathleen and Glenn Dellmann. The family moved to Poynette in 1986. Greg was a proud graduate of Poynette High School, where his lifelong love of music started. He then graduated from Madison Media Institute and followed his passion into sound, production, and performance, dedicating himself fully to his craft.
Greg shared his life with his beautiful partner, Desiree Tiffany, and his amazing children — Grayson, Rayne, Braelyn, Jordan, Lilith, and Trinity, who adored him. He had currently been working at Full Compass Systems where his professionalism and humor made the workplace brighter.
Greg was a pillar in the Wisconsin music scene. He was the heartbeat behind so many moments of magic. He believed in artists before they believed in themselves, opened doors for new voices, and promoted shows that gave bands their first break. Greg didn't care if your music didn't fit the mold-if it came from the heart he gave it a stage. He built a community of mutual respect and creativity and that generosity changed lives. Greg and Desiree owned 301 Productionz, Studio 301, and were creating music in their bands, avé Imperator and Grindge.
To his family, friends, and loved ones, words can hardly express the pain of this loss. Greg was the beloved partner and twin flame to Desiree, who shared his dream. His sudden passing is a tragedy that has shaken everyone who loved him; but his legacy will never fade. Every artist he lifted, every note that echoed from his venues, and every life he touched continues to carry his energy forward. Greg embodied what it means to live passionately and give selflessly. The music will play on, but there will forever be a silence where his laughter and light once stood. May his memory inspire us to keep creating, believing, and moving forward just as he always did.
Rest in peace Greg. Your sound will never fade.
Greg is survived by his parents; his twin flame; his children; his brothers, Dan and Jeff (Andrea); and his sister, Lissa. He also leaves behind many relatives and close friends.
He was preceded in death by his grandparents; his sister-in-law, Junko Dellmann; and his uncle and godfather, Michael Francois.
A celebration of life will be held on December 6th, 2025, at Studio 301.
Pflanz Mendrala Funeral Home, in Poynette, is assisting the family.
