“If we don’t take care of OUR PEOPLE, they won’t be able to take care of THE PEOPLE!”
Those words describe John Marx’s legacy of working with law-enforcement professionals and other first responders.
Sadly John Marx passed away on Oct. 16 after a long battle with pancreatic cancer.
His voice may be silenced but his impact, his passion and commitment to helping bring wellness and resilience to law-enforcement professionals will continue.
His legacy is the Law Enforcement Survival Institute (LESI), an assessment, consulting and training organization. In addition to this work, John also created Cops Alive (copsalive.com) and authored Armor Yourself: How to Survive a Career in Law Enforcement.
As a former law enforcement officer for twenty-three years and a hostage negotiator for nineteen of those years, John lost a good friend, also a former police officer to suicide. John created CopsAlive.com to save the lives of the people who save lives.
His body of work over the years has been used by law enforcement agencies all over the United States and Internationally.
While John will be missed by the thousands of people he worked with over the years, his work will continue. Please visit our websites for updates in the near future.
