With more than a decade of experience in domestic and international security services, Chief Gavin Montgomery has established himself as a strategic leader and founder of Liongate Security, a firm delivering tailored executive protection and event security for high-profile clients across the United States. Based in Atlanta, Georgia, Liongate Security has built a reputation for professionalism and discretion, serving public figures, entertainers, and executives with a high degree of tactical coordination.
Chief Montgomery, a graduate of the University of Arkansas at Pine Bluff with a Bachelor of Science in Communication, began his professional career with an understanding of public interaction and message control—skills that later became instrumental in de-escalation and leadership in high-stakes security environments. Over the past decade, he has advanced from providing protection services to managing large-scale security operations, eventually founding Liongate Security in January 2016. Under his leadership, the company has grown to manage multimillion-dollar accounts and staff over 20 major event venues across the Atlanta metropolitan area.
The operational capacity of Liongate Security extends beyond conventional event staffing. The firm has successfully organized and executed protection plans for events exceeding 700 attendees and has consistently collaborated with law enforcement to ensure compliance, safety, and order. Montgomery personally oversees payroll, scheduling, and daily administrative duties, maintaining a hands-on approach to business management that aligns with the high standards of the clientele the company serves.
In the arena of executive protection, Chief Montgomery has provided services to several prominent figures in entertainment and corporate leadership. While details of individual clients remain confidential due to nondisclosure agreements, his experience spans a wide range of assignments, from high-profile event protection to 24-hour home surveillance and residential safety planning.
The scope and consistency of these engagements underscore the reliability and tactical expertise that clients have come to associate with both Montgomery and his team. The firm’s approach emphasizes advance planning, coordinated movements, and scenario-specific protocols that meet the unique needs of each client and situation. Montgomery’s ability to direct operations in diverse and dynamic environments demonstrates a rare blend of leadership, strategy, and responsiveness under pressure.
In addition to his practical credentials, Montgomery holds several advanced qualifications, including a Georgia Pistol and Rifle Certification at the Expert level and licensure as a Private Investigator in Atlanta. He is also trained in Brazilian Jiu-Jitsu, boxing, and close quarter combat, bringing a physical readiness that complements his strategic acumen. A former Division I basketball athlete, he credits sports with developing the discipline and resilience necessary for high-performance roles in the private security industry.
Montgomery advocates for the involvement of former athletes in the security field, citing shared values of teamwork, commitment, and tactical execution. He is also the host of The Doormen Podcast on YouTube, where topics range from professional security techniques to industry trends—reflecting his broader commitment to professional development and thought leadership within the executive protection space.
While Liongate Security continues to expand its operations and service offerings, its reputation in Atlanta remains rooted in trust, preparedness, and unwavering professionalism. Montgomery’s direct involvement in each aspect of the company—from frontline operations to strategic planning—has contributed to its continued relevance among discerning clients who require discretion, control, and comprehensive protection.
