In a rapidly shifting American political landscape, few debates ignite as much passion, misunderstanding and urgency as
firearms policy. At the intersection of that national conversation stands Dianna Muller, a retired law enforcement professional, elite competitive shooter and founder of Women for Gun Rights. Her story is one of discipline under pressure, competitive excellence and an unwavering commitment to education, empowerment and constitutional freedoms. At an early age, Muller’s father, a highway patrolman, taught her gun safety and started her shooting. When he took her to a United States Practical Shooting Association, or USPSA, match, she was intrigued by the running and gunning. While in high school she started competition shooting. For 18 years Muller also pursued horse shows and barrel racing.
After earning a Bachelor of Science degree in Criminal Justice and Psychology from the University of Central Missouri, Muller continued to hone her skills while serving in law-enforcement. She moved to Tulsa, Oklahoma, and began working as a police officer for the Tulsa Police Department. For 22 years, she worked assignments that ranged from patrol and street crimes to narcotics and gang units. Those decades on the front lines shaped not only her understanding of firearms as tools of public safety, but also her conviction that responsible ownership, consistent training and education (not prohibition) are the most effective means of reducing violence. A Council on Law Enforcement Education and Training-certified firearms instructor, Muller spent her law enforcement career immersed in both training environments and real-world application, experiences that would later anchor her advocacy work and distinguish her voice in policy discussions.
IT WAS DURING this period that she found her true competitive calling in multi-gun competition, and particularly 3-Gun, a demanding discipline requiring mastery of pistol, rifle and shotgun under intense physical and mental pressure. Her professional foundation seamlessly merged with a parallel passion: competitive shooting. Drawn to its complexity and precision, Muller made a bold and unconventional decision in 2009: She sold her farm and barrel racing horses and transitioned from police officer to professional shooter, committing fully to competition at the highest levels. It was a gamble few would take, but one that paid off decisively.
Muller’s competitive résumé places her among the elite of the shooting sports world. She is a two-time USPSA Ladies Open National Champion and also captured the 2015 NRA World Shooting Championship Ladies title, underscoring her versatility
across multiple platforms. On the international stage, she has represented the United States with distinction at the International Practical Shooting Confederation (IPSC) World Shotgun Championships, earning individual silver medals and contributing to team gold finishes against the world’s top competitors.
Her success has continued well into the current decade. In 2025, Muller once again stood on the world podium at the IPSC Pistol Caliber Carbine and Mini Rifle World Shoot in the Czech Republic, taking home individual and team silver medals in one of the most competitive international fields the sport has seen. Domestically, she claimed Hi-Lady honors at the Texas State 3-Gun Championship, reaffirming her reputation for excelling under the most demanding conditions. These achievements reflect not only technical mastery, but resilience competing at an elite level across decades in a sport that rewards precision, preparation and mental toughness.
YET MULLER’S INFLUENCE extends far beyond trophies and titles. After retiring from active law enforcement, she turned her experience toward advocacy, founding Women for Gun Rights, a nonpartisan organization dedicated to protecting the Second Amendment through education rather than restrictive legislation. WGR operates on three core pillars: education, preservation and advocacy. Its mission centers on informing communities and lawmakers about firearm safety and responsible ownership, protecting America’s hunting and shooting heritage, and elevating the voices of women – one of the fastest-growing demographics of gun owners in the United States.
Under Muller’s leadership, WGR has grown into a nationwide grassroots network with state directors and community leaders
actively engaged in the policy process. The organization regularly participates in legislative hearings, national conferences and public testimony at both the state and federal levels. In 2025, WGR delegates testified at the Massachusetts State House on proposed firearm legislation, representing everyday citizens: mothers, professionals and small-business owners who believe constitutional rights and public safety are not mutually exclusive.
Muller herself has become a prominent and frequently called upon voice in contemporary firearms policy debates. She has
testified before Congress, including appearances before the House Judiciary Subcommittee on Crime, where she has argued that enforcement of existing laws, combined with education and training initiatives, is far more effective than sweeping bans that disproportionately affect law-abiding citizens. Central to her mission is ensuring that women’s perspectives are not merely present, but influential in shaping the future of firearms policy.
Education remains a defining thread throughout Muller’s work. On the range, she continues to mentor shooters of all experience levels, emphasizing safety, accountability and confidence. Alongside her husband Ryan Muller, himself a decorated competitive shooter and instructor, she cofounded Ambassador Academy, an immersive program designed to develop informed, articulate
representatives for the shooting community. The academy focuses on media literacy, policy understanding and effective communication, preparing participants to engage responsibly in public discourse.
The Mullers’ commitment to responsible growth of the sport is further reflected in their roles as brand ambassadors for the NRA’s America’s Rifle Challenge, an initiative aimed at promoting safe handling, marksmanship and structured competition for AR-platform rifles. Through these efforts, Muller continues to bridge the gap between sport, safety and civic responsibility.
WHAT SETS MULLER apart is her comprehensive approach. She embodies a philosophy in which excellence, safety, discipline and civic engagement coexist. Whether she is strategizing on the firing line, mentoring first-time competitors, organizing grassroots advocates or addressing policymakers in Washington, DC, Muller represents a modern vision of the shooting sports – one defined not just by precision, but by purpose. As the national conversation around firearms continues to evolve, Muller and Women for Gun Rights remain focused on redefining what leadership in this space looks like: informed,
inclusive and unapologetically committed to individual liberty. Her journey from law enforcement officer to world-class competitor and national advocate stands as a testament to the power of experience, education and resolve in shaping both sport and policy on the world stage. Dianna Muller is an amazing person and women from around the world can look up to her for what she believes in and what she has accomplished. ★
