Transforming Women into Skilled Confident Protectors
When former MMA fighter Gemma Sheehan hung up her gloves, she knew her journey with martial arts was far from over. What began as a career in competitive fighting — where she earned a 5–1 record and became Ontario, Canada’s top-ranked female MMA Fighter — evolved into something far more profound.
Gemma had discovered the real fight wasn’t inside the cage. It was giving women and girls the confidence and tools to protect themselves in real life.
In 2017, Gemma founded Girls Who Fight, a training center dedicated exclusively to women’s and girls’ self-defense. The mission was simple yet revolutionary: create a safe, empowering space where women could learn practical, effective skills from mixed martial arts — without the intimidation or competition-driven focus of traditional martial arts gyms.
“Martial arts changed my life,” Gemma said. “It gave me confidence that I could succeed and overcome anything. That’s what I wanted to pass on — skills that build not just physical strength, but self-belief.”
Redefining Women’s Self-Defense
What sets Girls Who Fight apart is its laser focus on women’s safety. While most martial arts programs are designed for men and competitive athletes, Gemma’s approach is built entirely around the real-world situations women face. FBI data shows that 89% of sexual assault victims are female and that women are disproportionately targeted for violence.
At Girls Who Fight, the curriculum tackles those realities head-on. The Women’s Self Defense Beginner Course, the studio’s most popular program, is a 6-week series teaching defenses for common attacks and how to use awareness, boundary-setting, and verbal strategies.
Each class is taught in a positive and supportive environment — where beginners feel welcomed from day one. “Every class feels like having fun with your best friends,” Gemma shares. “The energy, the friendships, the laughter—it’s not just training. It’s community and transformation.”
Safe Space for Growth & Connection
What Gemma treasures most about her work isn’t just the skills her students master — it’s the community that forms within the walls of Girls Who Fight.
“We’ve created a culture where every woman who walks in feels seen and supported,” she explains. “There are no cliques, no egos, no intimidation—just women lifting each other up.”
That sense of connection often leads to profound personal breakthroughs. Students have shared how their training gave them the courage to set boundaries, speak up in uncomfortable situations, and even feel safer walking alone at night. “You see it in their posture, their tone, their energy,” Gemma said. “They carry themselves differently — like they finally believe in their own strength.”
One of Gemma’s most memorable stories comes from a recent Beginner course graduate named Courtney, who survived an abduction before joining the program.
“Girls Who Fight has truly been life-changing for me. After experiencing a situation where my safety was seriously threatened, I struggled with confidence, trust in myself, and a lingering sense of powerlessness that kept me feeling stuck. From the very first class of the beginner course, Gemma created an incredibly empowering and safe space to grow. She is not only knowledgeable and skilled but also deeply supportive, making sure everyone feels strong, capable, and in control. Her teaching goes beyond physical techniques, it’s about rebuilding confidence, trust, and a sense of personal power. With every lesson, I feel more empowered, more capable, and more excited for life again after an event that left me feeling pretty helpless.”
Courtney is still training one year later, pursuing mastery of women’s self defense and safety skills that she can one day teach others.
A Mission That Grows with the Community
Over the years, Girls Who Fight has grown into one of the largest women’s-only self-defense programs in the world, surpassing 100 active students. The studio recently launched a Leadership Program, helping girls develop character, confidence, and leadership skills alongside their self-defense training.
Their youth programs — Girls (6-14) and Teens (14-17) — focus on building “superhero-level confidence” through self defense and character development training. Beyond the physical benefits, the lessons instill self-discipline, respect, focus, resilience, and the belief that strength and kindness can coexist.
Gemma’s impact has not gone unnoticed—she was recently honored with a State of Texas Resolution from the House of Representatives recognizing her dedication to the safety and wellbeing of women and girls across the region.
Empowering a Global Movement
Girls Who Fight’s influence extends far beyond the studio. After one of Gemma’s videos demonstrating a hair-grab defense went viral — earning over 18 million views — the studio’s online presence exploded, reaching 330,000 followers on Instagram and 165,000 on TikTok. Through social media, Gemma has been able to inspire women around the world to take self-defense into their own hands.
She’s equally proud of her students’ everyday victories—like one teen who overcame her fear of performing in front of a crowd, another who earned a spot on the state band team, and a third who finally stood tall giving a class presentation. All of which credited their training at Girls Who Fight to “Stand Like A Champion.”
“Those are the moments that matter most,” Gemma said. “It’s not just about defending yourself physically — it’s about knowing you can handle anything life throws your way.”
From local classes to global impact, Girls Who Fight continues to redefine what empowerment looks like. It’s more than a studio — it’s a movement that turns fear into strength, and uncertainty into confidence.
Gemma puts it best: “We’re not just teaching self-defense—we’re transforming women into skilled, confident protectors.”
