Kewesi went from a troubled youth to becoming a successful martial artist and entrepreneur. He overcame a chaotic adolescence, involvement with gangs, and a stint on the streets to find purpose in martial arts. He has trained in various styles, including Old Style Muay Thai, Military Muay Thai, Kali, Jujitsu, and Escrima, under renowned instructors like Dr. Nirmalya Bhowmick. Kewesi's journey has taken him from training in martial arts to working as a bouncer in Oakland for 15 years, where he honed his skills in self-defense and conflict resolution. He eventually opened his own school, KESFITNESS, and shifted his focus to mobility and corrective exercise, becoming certified in Tui Na and Reposturing.
