Founder / Instructor

Terence L. Brister Sr.

Mr. Brister is currently a Certified Law Enforcement Officer who lives in Greenville SC. He is a Former State Trooper, USMC Sgt. , Former Federal Security Contractor, Former Professional Investigator, Author, and professional fitness coach/instructor. He is passionate about serving the community by providing the best self-defense and personal training instruction in the Upstate. He and his family/friends often volunteer and serve the marginalized and homeless populations in the city. Most importantly he wants to share his faith,  leading others to a personal and intimate relationship with Christ. 

Unified Self-Defense was created to keep people safe. Mr. Brister wanted a professional self-defense program that was unlike any other. It trains the mind, body and spirit to improve situational awareness and combat all types of violence. The teaching method is described as professional, informative, fun, and simple. This concept and passion for reality-based self-defense came from my experience and career that exposed me to  the harsh reality of abuse, neglect, violence towards women and criminal activity.

She learned reality-based self-defense, and strength training to improve her personal safety and fighting confidence. After doing so well, she decided that she wanted to invest her time, energy and resources in helping other women learn self-defense and enhance their quality of life. She often shares her story with others who have similar experiences and it creates camaraderie and allows the women to be vulnerable and relate to one another in and out of the classroom.
