Fire Chief Jeff Isaacs from the Moraga-Orinda Fire Protection District confirmed that paramedics responded to the scene, although he did not disclose further details surrounding the incident. Saint Mary’s College shared the news on social media, expressing profound sorrow and sending heartfelt condolences to Peterson’s family and friends. “This is heartbreaking for our community… Dominic’s smile was contagious and one that would brighten a room when he entered,” the college stated in their tribute.
Peterson was well-respected and admired among his peers and coaches. He had previously served as co-captain of an international rugby squad and played a pivotal role in the national Under-19 team that emerged victorious in the Rugby Americas North Championship. Tim O’Brien, head coach of the rugby team, reflected on Peterson’s remarkable potential and dedication to the sport, remarking, “He was an up-and-comer; he was hitting higher highs. How does a 19-year-old guy at the top of fitness all of a sudden die? It’s hard to describe.”

The local community turned out in large numbers to honour Peterson’s legacy at a memorial mass held at the college the Saturday following his death. O’Brien noted that attendees filled the venue “shoulder to shoulder,” illustrating the impact Peterson had on those around him.

In the wake of this tragic event, a fund has been established in Peterson’s memory to support the Saint Mary’s College rugby programme. The initiative aims to ensure that future student-athletes have access to opportunities and experiences similar to those enjoyed by Peterson. The college extended an invitation to all who knew him, including family, friends, and teammates, to contribute and pay tribute to his memory.
“This fund will support the ongoing needs of Men’s Rugby, helping provide opportunities for the student-athletes who make up Dominic’s rugby community,” the college’s announcement explained. It serves not only as a way to remember Peterson but also as a means to foster a lasting legacy within the rugby programme at Saint Mary’s.
The College Rugby Association of America has also expressed its condolences to Peterson’s family and friends. Paul Keeler, executive director of the association, acknowledged the profound loss felt throughout the rugby community, stating, “The loss of a young man and teammate in circumstances like these is difficult to comprehend.” He further emphasised the deep connections formed within the sport, highlighting that losing one member of the team resonates across the whole community.
As inquiries continue into the circumstances of Peterson’s collapse, both Saint Mary’s College and the Moraga-Orinda Fire Protection District have not provided additional comments. The college remains focused on supporting its students and honouring the memory of a young man whose promise and enthusiasm left a significant mark on those fortunate enough to know him.
The death of Dominic Peterson serves as a poignant reminder of the fragility of life and the tight-knit bonds shared within the sporting community. While his passing is a source of profound grief, his legacy is set to live on through the initiatives in his memory and the cherished memories held by all who had the pleasure of witnessing his journey both on and off the field.
