The global music community is in mourning following the death of Chad Gilbert, the foundational guitarist, songwriter, and co-founder of the influential pop-punk band New Found Glory. Gilbert passed away on the morning of September 20 at the age of 45, following a courageous, multi-year battle with an aggressive, rare form of cancer.
For nearly three decades, Gilbert was the creative engine behind New Found Glory, a band that helped define and shape the modern landscape of alternative rock and pop-punk. Diagnosed in 2021 with a rare adrenal gland malignancy that ultimately progressed to stage 4 adrenocortical carcinoma, Gilbert faced his diagnosis with immense resilience. He underwent numerous high-risk surgeries, intensive chemotherapy treatments, and continuous health setbacks. Yet, his public transparency throughout his medical journey served as a beacon of courage for millions of fans worldwide.
Gilbert is survived by his wife, Lisa Cimorelli; their five-year-old daughter, Lily; his mother, Jackie; and his brother, Brian. As tributes pour in from across the music industry—honoring his contributions not only to New Found Glory, but also to hardcore outfits like Shai Hulud and International Superheroes of Hardcore—his passing marks the close of a definitive chapter in 2000s rock history. His bandmates, family, and peers remember him as a musical pioneer, a fierce collaborator, and, above all, a devoted father and husband.
Detailed Chronology: A Battle Fought with Resilience
Chad Gilbert’s health struggles unfolded publicly over several years, marked by a series of grueling medical interventions, unexpected setbacks, and moments of hard-fought remission before the aggressive nature of his disease ultimately took over.
December 2021: The Initial Discovery
Gilbert’s medical journey began unexpectedly in late 2021 when he was found unresponsive in bed by his family. Emergency medical protocols were activated, leading to his hospitalization. Doctors discovered a rare cancerous tumor on his adrenal gland. He underwent immediate, high-stakes surgery to remove the mass. At the time, the operation was deemed successful, and Gilbert expressed optimism about returning to music and family life, though oncologists closely monitored his recovery due to the unpredictable behavior of adrenal malignancies.
August 2022: Spinal Complications and Secondary Surgery
Less than a year after his initial diagnosis, Gilbert announced that the cancer had returned. Medical imaging revealed a new tumor pressing against his spine, creating an urgent surgical imperative to prevent neurological damage. The successful spinal procedure required a rigorous physical rehabilitation process, testing Gilbert’s physical endurance. Despite the compounding health hurdles, he continued to write music, support his family, and maintain an active connection with his fanbase, who flooded social media with messages of encouragement.
February 2023: Intensive Chemotherapy and Rare Discoveries
By early 2023, the disease’s complexity deepened. Doctors discovered rare pheochromocytomas—catecholamine-secreting tumors—embedded in his lungs and back. This necessitated the commencement of heavy, targeted chemotherapy regimens. Pheochromocytomas are notoriously difficult to treat due to their hormonal side effects and aggressive cellular proliferation, but Gilbert approached the grueling treatment cycle with the same tenacity that characterized his decades-long career in punk rock.
2024–2025: Brain Surgery and Stage 4 Progression
Gilbert’s medical challenges escalated further as new scans revealed three additional tumors, this time located in his brain. This required yet another major surgical intervention. In April, following the brain surgery and subsequent staging assessments, Gilbert shared an updated prognosis with the public: his condition had advanced to stage 4. Despite the terminal classification, Gilbert remained focused on quality of life, spending precious moments with his wife, Lisa, and his young daughter, Lily.
September 20, 2025: Peaceful Passing
Gilbert passed away peacefully in his sleep on the morning of September 20. According to statements released by his family, he spent his final hours surrounded by a vast network of friends and loved ones who had rushed to the hospital. He took his final breaths with his wife and mother by his side, fulfilling his final wishes.

In lieu of traditional flowers, family representatives have indicated that memorial contributions and fan tributes are being channeled toward supporting pediatric cancer research and adrenal carcinoma awareness campaigns—causes that Gilbert passionately supported during his own battle. Furthermore, tributes are already being planned within the alternative festival circuit for the upcoming summer concert season, ensuring that the legacy of one of pop-punk’s defining architects will continue to inspire new generations of musicians and fans alike.
