Jim “Doc” Amentler is a retired U.S. Navy Senior Chief Hospital Corpsman who served 22 years across multiple combat and overseas deployments, including Iraq, the Persian Gulf, and Africa. Earning the title of “Doc,” he was later given the nickname “Sensei” during his first deployment to Iraq for his uncanny ability to stay calm under high-pressure situations. He became known for his leadership and skill in keeping warriors alive under fire and in austere environments.

Today, as the founder of Alpha Safety Training, Doc carries that experience forward into civilian life. He is a certified firearms and trauma medical instructor specializing in Defensive Medicine, CPR/First Aid, Wilderness First Aid, and both California and multi-state CCW courses. His instruction combines tactical skill, real-world combat experience, and evidence-based medical practices, giving students the tools and confidence to act decisively when seconds matter.

Guided by his personal creed — “Don’t Die. Keep Them Alive.” — Doc empowers everyday people to step up in emergencies, bridging the gap between chaos and survival.
