Born and raised in Southern California, Troy is both a personal and professional survivor of multiple incidents of interpersonal gun and criminal violence. His firsthand experiences have given him deep insight into the necessity of self-defense.

​

For years, he has worked directly with communities as a mentor, coach, and advocate, addressing violent crime through community education, outreach, suicide prevention, trauma-informed behavioral health education, and legislative advocacy. A major focus of his work is reducing victimization by educating and training individuals in self-defense laws, situational awareness, body language and pre-assault indicators, communication skills, crisis and conflict de-escalation, lawful use of force (both lethal and non-lethal), firearms tactics, improvised weapons, and empty-hand defense.

​

Troy specializes in trauma-informed training, recognizing that every individual brings a unique life experience to personal survival. He believes that self-defense education must honor each person’s background, including the way they learn to protect themselves and others.

In 2018, Troy combined his knowledge, skills, personal experiences, education, and certifications with his passion for training others in psychological fitness, personal survival, physical fitness, tactical fitness, and personal defense and founded Time 4 Change, LLC. In 2020, he expanded his mission by launching Core Concepts Tactical Defense to further empower individuals in self-defense and personal protection.
