Master of Arts in Homeland Security, American Military University

Bachelor of Science in Public Health, American Public University


Hello from sunny San Diego, California. My name is DJ Phalen (aka Prof D), Program Director and Professor for the Homeland Security program at Waldorf College.

I earned my Master of Arts in Homeland Security with honors and a Bachelor of Science in Public Health with honors and am a lifetime member in several honor societies: Epsilon Pi Phi Emergency Management (Homeland Security Honor Society), Pi Gamma Mu International Honor Society in Social Sciences, Delta Epsilon Tau International Graduate Honor Society, Psi Chi - National Honor Society in Psychology, Golden Key International Honor Society, and the Order of the Sword & Shield National Honor Society (Omicron Sigma Sigma). I also hold the national Certified Homeland Protection Professional (CHPP) designation awarded by the National Domestic Preparedness Coalition and the Terrorism & Homeland Security Specialist designation awarded by the California Emergency Management Agency (CalEMA) and California Specialized Training Institute (CSTI).

My professional experience is in the fields of counterterrorism/homeland security, EMS/Special Operations EMS (rescue and tactical medicine), firefighting, and healthcare/ healthcare leadership. I am a member of a number of professional associations such as the International Association for Counterterrorism & Security Professionals (IACSP), International Association of Emergency Managers (IAEM), International Counter-Terrorism Officers Association (ICTOA), International Association of Interviewers (IAI), and the Special Operations Medical Association (SOMA).

I have a very eclectic background…but there is a method to the madness. I served in the United States Navy from 1991-1995 (the first Gulf war) aboard an amphibious assault ship. I have worked in healthcare since 1994 as an EMT, ER Technician, and as clinic/hospital executive staff. I also served as a Medic/Technical Rescue Specialist with the Sheriff’s department, as a medic with federal disaster medical team DMAT CA-4, as a firefighter/EMT, and as a member of the San Diego Medical Reserve Corp (MRC).

In addition to teaching at Waldorf College (and CSU), I also served as the Medical Terrorism Liaison Officer (TLO) Coordinator at the San Diego Law Enforcement Coordination Center (SD-LECC) Terrorism Unit / Regional Terrorism Threat Assessment Center (RTTAC) where I developed the Medical Terrorism Liaison Officer (TLO) program. Currently I serve as the Sector Chief of the Healthcare and Public Health Sector for San Diego InfraGard (an FBI-affiliated organization). Additionally, I am a contracted Consultant / Subject Matter Expert doing course review of new/existing FEMA/DHS training courses, serve as a Subject Matter Expert (Homeland Defense and Security and Medical) for the Homeland Defense and Security Information Analysis Center (HDIAC), serve as the Counter-Terrorism / Hospital Counter-Terrorism Advisor/Trainer for The Halo Corporation, and regularly contribute to several peer-reviewed professional journals, newsletters, and blogs in the terrorism/counterterrorism and emergency management communities.

On the personal side…in my free time (which is rare these days) I like to hike, bike, and go trail-running. I am also a Muay Thai instructor (I started the program at the University of California San Diego). I also co-hosted a show on with a physician buddy of mine (boonDocs Wilderness and Travel Medicine) and you can check that out…several episodes up (two dozen more to come soon…in editing), but you cannot make fun of my acting…not my forte.

Good luck everyone and STAY SAFE! Please feel free to contact me anytime at: e-mail @ or Cell at 619-569-3607
