Early Life and French-Canadian Roots
Sylvain Desaulniers comes from a Franco-Manitoban background, meaning his family roots are connected to the French-speaking community in Manitoba, Canada. This is a relatively small but culturally rich community in Canada, where French is the main language of the home and community life.
His parents were Aurèle Desaulniers and Gabrielle Marie-Therese (Chatelain) Desaulniers, who were French-Canadians from Winnipeg. His mother, Gabrielle, passed away in December 2015.
This French-Canadian heritage had a direct effect on his daughter Brie. French was actually Brie Larson’s first language, which is a fun fact many fans do not know. Growing up in a bilingual household was part of what made Brie’s childhood unique.
Because of her father’s nationality, Brie Larson holds dual citizenship in both Canada and the United States. This is something she inherited directly from Sylvain’s Canadian background.

Education and Career as a Chiropractor
Sylvain Desaulniers chose a career in health and wellness. He attended Life West Chiropractic College in 1983 and graduated with his Doctor of Chiropractic in 1986.
What pushed him toward chiropractic care? Interestingly, the reason goes back to a personal experience. Sylvain was hit by a car, and this accident left him with a spine that was more susceptible to dysfunction and back issues. He received his first chiropractic adjustment shortly after the accident and has been receiving them ever since. This personal experience with chiropractic healing inspired him to make it his life’s work.
He graduated with honors from Life Chiropractic College West in 1986 and has since built more than 39 years of diverse experience, especially in chiropractic care.
After graduating, he began working for Danville Chiropractic in Danville, California, where he provided quality chiropractic adjustments as well as nutrition counseling and rehabilitation. He later opened his own practice called HealthQuest in Sacramento, California in 1990, where he also incorporated nutrition and functional medicine.
Over the years, his career continued to grow. He later practiced at Capitol Chiropractic until it closed in February 2017. He now owns his own practice, Zero Limits Chiropractic, located at 451 Park Fair Drive, Suite 4 in Sacramento, California.
His healthcare provider registration in the NPI registry was assigned in May 2007, and his practice specializes in helping patients with problems of the neuromusculoskeletal system, which includes nerves, bones, muscles, ligaments, and tendons.
Marriage to Heather Desaulniers
Sylvain met Heather Edwards, who would later become Heather Desaulniers, and the two built a life together in Sacramento. Both Sylvain and Heather were homeopathic chiropractors who ran a practice together. It was a true partnership, both at home and at work.
Together, they had two daughters: Brianne Sidonie Desaulniers, born October 1, 1989, in Sacramento, California, and another daughter, Milaine.
However, the marriage did not last. Larson’s parents divorced when she was aged seven. This was a turning point not just for the family, but especially for young Brie, who was still a child when things fell apart.
His Relationship With Brie Larson
This is perhaps the most talked-about part of Sylvain’s life, and it is not a happy story. After the divorce, the relationship between Sylvain and his daughters became very distant, particularly with Brie.
Brie Larson had a difficult relationship with her father, saying: “As a kid I tried to understand him and understand the situation. But he didn’t do himself any favors. I don’t think he ever really wanted to be a parent.”
These are strong words, and they paint a picture of a father-daughter relationship that was broken and painful. Brie has spoken about this topic more than once in interviews over the years, always being honest about the hurt she felt growing up without a close relationship with her dad.
After the separation, Heather relocated to Los Angeles with her two daughters to support Brie’s acting ambitions. They had limited financial means and lived in a small apartment near Hollywood studio lots in Burbank.
Even though life was hard financially, Brie has always praised her mother for being strong and supportive. Her father, on the other hand, remained a painful and largely absent figure in her life.
It is worth noting that Brie has shown in her work a deep interest in complex parent-child relationships and the theme of forgiveness. Many of her most powerful movie roles deal with these exact topics. In some ways, her personal experience with her father seems to have shaped the kind of stories she is drawn to as an actress.
The Name “Desaulniers” and Why Brie Changed It
One of the most direct reminders of Sylvain’s influence on Brie’s life is actually the stage name she chose to leave behind. Brie was born Brianne Sidonie Desaulniers, which is her father’s family name.
After a considerable period of frustration correcting people who consistently mispronounced her birth name “Desaulniers,” Brie changed it to Larson after her Kirsten Larson doll that she owned as a youngster.
She chose “Larson” as her stage name from her great-grandmother’s maiden name, as her surname was too difficult to pronounce. Her maternal great-grandmother was of Swedish descent, and the name Larson felt easier and more natural for an acting career in Hollywood.
So while Sylvain’s family name no longer appears on movie posters or award plaques, it is still a part of who Brie Larson is at her core.
Sylvain Desaulniers Today

While Brie Larson became a household name around the world, her father has continued living a quiet, professional life. He is not active on social media or in public life, and he rarely, if ever, speaks to the press about his famous daughter.

Sylvain is a piece of that puzzle. His French-Canadian heritage, his career as a chiropractor, his failed marriage, and his strained relationship with his daughter are all parts of the larger story of who Brie Larson is as a person.
At the same time, Sylvain’s story is also interesting on its own terms. He is a man who built a healthcare career from personal hardship, who came from a French-speaking community in Canada, and who eventually settled in California. His life, though less glamorous than his daughter’s, is still worth knowing about.
