Casey Fryer

Casey brings his extensive background as a martial artist and survival teacher/trainer to our training team. His broad knowledge base in self-protection and self-reliance gives the everyday citizen a path to preparedness and survival in very challenging environments.

Casey’s training in martial arts began in 1998 under world renowned 5th generation master Gin Foon Mark where his focus was on kung fu techniques, feeling, timing, and Chi Kung. He expanded his training under the guidance of Joe McSorley in Philadelphia to study the more deliberate, defensive applications of the Southern Praying Mantis style of kung fu. He achieved a rank held by a total of five people, 6th Generation Closed Door Disciple, and later SiFu. 

Casey has received extensive wilderness survival training at The Tracker School under the direction of Tom Brown Jr where he was taught the ways of a Lipan Apache Scout/Shaman known as Stalking Wolf. After many courses and plenty of “dirt time” in training, he was offered a spot in a private group within The Tracker School. Upon acceptance, he became part of the Keepers of the Shadows, Scout division, and Wind Walker clan.

Casey is a USCCA certified Firearms Instructor and Range Safety Officer, a nationally certified Fitness Trainer, and Nutritional Coach, and a nationally certified Kundalini Yoga Teacher as taught by Yogi Bhajan.


C.T.A.C. is rooted in the two paramount principles for defending yourself with a firearm:

1. Identify and know what you are shooting at.

2. You need to hit it.

CTAC prioritizes mastery of pistol fundamentals to subconscious competence, moving and shooting, decision-making under stress, and primary trauma care for protecting yourself while armed.
