Mr. Esquilin served his country in the U.S. Navy for over 18 years before being affected by a physical disability.  In his various capacities of service – his last assignment was as a Navy Instructor (with over 1000 podium hours) tasked with travel throughout the U.S. and foreign countries, training both officers and senior non-commissioned officers on how to effectively convey information and training material as instructors themselves.  His interest in the physical security arena spawned from his military service – and developed into an after Navy career employment opportunity.  He accrued years of experience supporting in a Supervisory or Management office - commercial security services from retail establishments, to Section 8 Housing developments, and then as a Personal Protection Specialist and Private Investigator.  His background in the government security guard sector is as extensive, having worked his way from a post assigned officer to an Area Services Manager, leading to his return to his primary interest of Security Instruction.

   As the founder of EXCELSIOR Security Training Academy, Mr. Esquilin brings over thirty (30) years private sector Physical Security experience to each class he instructs. Running the gamut from serving as a Field Project Manager on numerous federal government General Services Administration (GSA) / Department of Homeland Security (DHS) contracts from Director of Housing Security to large and small Section 8 Housing projects, Mr. Esquilin has experienced every aspect of the physical security arena.

    He is a long time state certified armed/unarmed security officer training instructor in Maryland and Virginia; as well as being certified to train the various GSA/DHS Contract Guard/Physical Security Officer courses. As an Instructor in a number of subject areas including various types of firearms, CPR/First Aid/AED, Expandable Baton, and Private Investigations - Mr. Esquilin and his staff, impart a clear sense of the manner in which Physical Security Officers should carry out their assigned duties.  The result is trained officers that reflect the highest levels of Courtesy – Professionalism – and Responsibility to task assigned.

     To that end, Mr. Esquilin, and the staff of EXCELSIOR Services - Security Training believe that their most important function as Physical Security Officer Instructors is “Arming Students With Knowledge.
