SERVING THOSE WHO SERVE

Alexander Leoni is a United States Marine Corps veteran with six years of honorable service, including deployments overseas where he specialized in aviation ordnance and embassy security. His time in the Marine Corps forged not only his physical toughness but also his unwavering resilience and leadership, both of which would later shape his future endeavors in private security and tactical operations. After his military service, Alexander transitioned into executive protection and private security, where he refined his skills in situational awareness, risk mitigation, and operational coordination.

​

However, it was a life-altering experience during his deployment—a real encounter with a wild lion—that left Alexander physically and psychologically scarred. That moment awakened a deeply primal instinct within him, one that refused to be silenced. This inner savagery, combined with the emotional weight of military trauma, led to the birth of Manganni Salvaticus and the creation of the Manganni Jungle.

​

The Manganni Jungle is more than an obstacle course—it's a sanctuary for transformation. Built to be a workshop for the soul, mind, and body, it features a continuous jungle of ropes, rings, tires, and natural terrain, designed to challenge both physical endurance and spiritual resilience. Within it, the sport of Jungle Athletics was born. Participants are required to move using specific primitive movements, and navigate a system that blends air-based components with lane-based ground progression—creating an experience unlike any other.

​

Alexander also envisioned the Manganni OpsVillage, a tactical training village within the Jungle, designed to simulate combat and security operations. It serves as a bridge between veterans and civilian participants, providing a healthy outlet for energy, competition, and camaraderie.

From this powerful foundation emerged the United Manganni Veterans project, an initiative focused on suicide prevention among veterans. The program offers amputee veterans a place where they can compete, thrive, and feel fully included through innovations like “The Claw”, a prosthetic arm specifically designed to enable hand-amputees to participate in Jungle Sports. For able-bodied veterans, it offers physical release and brotherhood through activities like airsoft battles, obstacle training, and team challenges.

​

In 2021, Alexander joined the Collier County Veterans Council as Vice President, continuing his service to the veteran community. In March 2025, he was appointed President of the Council, further expanding his leadership role and impact on veteran advocacy in Southwest Florida.

In 2024, Alexander accepted the calling to become the Youth Pastor at Genesis Church, where he now works directly with the next generation to influence their lives for a brighter future and a closer walk with God. Through mentorship, discipleship, and service, he helps guide young people toward purpose, identity, and strong spiritual foundations—empowering them to rise as leaders in faith and character.

​

Alexander’s mission is global. He plans to bring Manganni Jungles to every continent and eventually to the Olympics and Paralympics, establishing Jungle Sports as an international athletic discipline. For Alexander, this isn’t just sport—it’s purpose.
