John F. Muffler, M.S.

John Muffler, Principal of Aequitas Global Security, LLC, is an accomplished law enforcement professional with more than 28-years experience in the field with an emphasis on leadership and high-level security matters. John served the United States Marshals Service as the Administrator of the National Center for Judicial Security. In addition to his capacity with the U.S. Marshals Service, where he was tasked with protecting hundreds of personnel, facilities, and at-risk public officials, he has worked in the private sector to support the development of national-level protection plans, the development of physical security programs, and developing comprehensive risk-assessment tools for a variety of clients. 

Examples of his work include the development and use of multi-disciplinary threat assessment teams that advise hundreds of schools and workplaces on protective, prevention, and intervention approaches related to behavioral violence; the development of the Department of Homeland Security’s national-level Active Shooter Preparedness curriculum; and, ongoing counsel and advisement for clients on short and long-term threat case management strategies.

In addition to his professional services, John volunteers his expertise for victims of harassment, stalking and violence. After the Parkland, FL, mass-casualty event, he volunteered time for a family of one of the victims offering guidance; traveling to Washington, he met with various United States Senators and Congressmen with the goal of establishing national school safety and security standards. 

John received his Bachelor of Arts in Criminal Justice from Temple University, Master of Science in Criminal Justice from St. Joseph's University, and is a graduate of the Naval Postgraduate School Executive Leaders Program. He is a member of the International Association of Chiefs of Police and on the committee of the International Managers of Police Academy and College Training (IMPACT), the Association of Threat Assessment Professionals, and National Sheriffs’ Association. He proudly serves on the Advisory Board of Blue HELP, whose mission it is to stem law enforcement suicide and its stigma.
