The martial arts community in Rochester, Minnesota, is reeling from the sudden and heartbreaking loss of Jason “Dingo” Mulholland, a deeply respected Brazilian Jiu-Jitsu instructor at Mario Roberto Jiu-Jitsu Academy.
Jason passed away unexpectedly, leaving behind not only his students and teammates but also a legacy of kindness, humility, and unmatched dedication to the craft and the people around him.
Jason was more than a coach—he was a mentor, a motivator, and a pillar within the gym family. Known affectionately by all as “Dingo,” his energy was unmistakable.
He brought laughter to the toughest rolls, offered wisdom with no judgment, and always made time for others, whether they were seasoned competitors or brand-new white belts walking onto the mat for the first time. His loss is being felt deeply across the entire community.
In a heartfelt statement shared by the gym, his team expressed their sorrow:
“Today, our gym lost more than a coach—we lost a great friend, a trusted training partner, and a mentor to many. His presence on the mats, his unwavering kindness, and his constant willingness to help others made our community stronger, better, and more united.”
Jason had a rare gift for teaching. His approach to Brazilian Jiu-Jitsu was rooted not only in technical excellence but also in his ability to connect with people. He understood that Jiu-Jitsu was as much about personal growth as it was about physical skill, and he embodied that principle every day.
His classes were known for being challenging but fun, disciplined yet filled with laughter—an extension of his own unique personality. Outside of the gym, Jason was a beloved friend to many. His sense of humor, loyalty, and laid-back nature made him a joy to be around.
He had a way of putting people at ease, often using his quick wit to brighten someone’s day or diffuse a tough situation. To know Dingo was to know someone who lived fully, cared deeply, and brought light wherever he went.
The news of his passing has brought an outpouring of love and grief from across the local and regional martial arts community. Teammates, students, and fellow instructors have all shared memories of Jason’s generosity, his encouragement, and the indelible mark he left on their lives.
“He believed in us, even when we didn’t believe in ourselves,” one student shared. “That’s the kind of coach he was. That’s the kind of person he was.”
Details surrounding the cause of Jason’s death have not been made public, as his family and friends continue to process this devastating loss. In this time of mourning, the community has come together to support one another, honoring Jason by carrying forward the lessons he taught—on and off the mats.
Plans for a memorial service or celebration of life are expected to be announced soon. The academy has also indicated they will be organizing a tribute event in Jason’s memory, inviting all who were touched by his life to come together in reflection and gratitude.
Jason “Dingo” Mulholland was not only an instructor but a foundational presence within his community. His impact cannot be measured solely by belts and titles, but by the confidence he instilled, the bonds he helped create, and the laughter he sparked during even the toughest days.
He will be remembered with love, missed beyond measure, and honored in the spirit he gave to all.
Rest in peace, Coach Dingo. Your legacy rolls on with every mat we step onto.
