As a police officer and security professional, Instructor Landry has been attacked several times with weapons and empty hands, “I had to utilize m combatives training on many occasions.” Instructor Landry was involved in undercover and task force operations as well where he.“had to take care of myself by myself in some of those assignments.”

    Hello, Dr. Landry. You encouraged me to pursue my dissertation, “Minimizing Injuries Related to Interpersonal Violence,” back at the beginning of my research in 2014. And it is going well, so thank you for your encouragement! I discovered SDTS while researching systems to be used for higher education self defense training, and am I happy that I did! This system is more flexible and available in a semester format than the Model Mugging, IMPACT or Rape Aggression Defense programs. I am in the data collection phase, and anticipate being done around May 2019. Thank you again, and welcome to SDTS! Bernie McPherson, Hawaii.
