Short Bio

John Marx is the Executive Director of the Law Enforcement Survival Institute (LESI) and author of the book Armor Your Self™: How To Survive A Career In Law Enforcement. He is Editor of the law enforcement wellness website www.CopsAlive.com.

John Marx served in law enforcement for twenty-three years in both a municipal police department and a county sheriff’s office. He served in patrol, investigations, community service and police administration. He was a hostage negotiator and team leader for 19 years and served his department as the administrator of their community policing project called Community Oriented Governance.

John founded The Law Enforcement Survival Institute (LESI) and started publishing CopsAlive.com after one of his friends, also a former sheriff’s deputy, completed suicide in 2007. The mission of both LESI and CopsAlive is to save the lives of the people who save lives!

As well as working with law enforcement agencies John also works as a private consultant providing training in the leadership development programs of Fortune 100 corporations like General Electric, Johnson & Johnson and Chevron.

Put simply, the mission of both LESI and CopsAlive is “Saving the Lives of Those Who Save Lives”.



When we say law enforcement professionals from around the world we mean anyone working in or around law enforcement — police officers, sheriff’s deputies, corrections officers, detectives, parole officers, probation officers, dispatchers, communications specialists, police supervisors, law enforcement managers, police wives, police mothers, police fathers, police children, police brothers, police sisters, police officer peers, and police officer partners.  This site is designed to share information to help ALL of us in the law enforcement profession.



We follow the same mission as CopsAlive.com, which was founded to provide information and strategies to help police officers successfully survive their careers.  We work to help law enforcement officers and their agencies prepare for the risks that threaten their existence.  We hope this information will help you and your agency create the kind of place that supports and protects officers so that they can do their jobs better, safer, longer and survive to tell their grand kids all about it.

Our Bottom Line:

We help law enforcement professionals plan for happy, healthy and successful lives on the job and beyond.
