ED GUERRA
Founder/CEO

With multiple deployments around the world and deep combat experience, he now leads Obsidian Spear Group—bringing hard-earned lessons to those who face danger head-on
"I started Obsidian Spear Group in 2024 to continue a calling that began in the Regiment—mentoring warriors. Some of my most rewarding moments in the military came from training new Rangers, helping them become more lethal, more decisive, and more resilient in chaos. I saw that same need in the law enforcement and civilian world. OSG was born to pass on not just what I learned from success, but also the hard lessons from failure—to equip today’s protectors with the mindset, skill, and heart to thrive in the fight." -- Ed Guerra
