The Stingray Allstars gym in Marietta is grieving, and the silence feels heavy. Shane Montgomery, a longtime tumbling coach known for his energy and heart, has died suddenly, leaving behind a community that is struggling to process the loss.
The program confirmed his passing in a message shared Tuesday, May 5. The tone was simple but deeply emotional. Staff and athletes described themselves as “deeply saddened,” calling Montgomery not just a coach, but a source of inspiration and guidance for so many young athletes who passed through the gym.

No cause of death has been made public. That uncertainty has only added to the shock. For many families, the news came out of nowhere. Parents, athletes, and fellow coaches quickly took to social media, trying to put into words what Montgomery meant to them.
To those who knew him, he was more than a coach running drills. He was the kind of mentor who gave everything he had. People say he poured his entire life into the athletes he trained. Long hours, constant encouragement, and a presence that made athletes feel seen and valued.
Inside the gym, his influence was easy to spot. Athletes didn’t just improve their skills. They built confidence. They learned discipline. They felt supported. Montgomery had a way of connecting, pushing athletes while still making them feel safe enough to grow.
The Stingray Allstars community made it clear that his impact will not fade. His love for tumbling and for the athletes themselves is expected to live on through every routine, every competition, and every young person he helped shape.
Right now, the focus is on remembering him the way he lived—full of passion, deeply committed, and always showing up for others. In a space built on teamwork and trust, his absence is deeply felt, but so is the legacy he leaves behind.
