Master Randolph started his Martial Arts training as a gift for his 11th birthday. He soon discovered a passion for it.

Master Randolph received his 1st Degree Black Belt at the age of 15, and continues his training under 10th Degree Black Belt, Grandmaster Jim Brassard, who has achieved countless awards, including one from President Obama himself. Master Randolph has been a leading competitor in tournaments since 1997, and in 2007 he achieved the coveted “Tournament Champion” – 1st Place in all three advanced Black Belt Instructor events: Kata, Weapons, and Sparring. In 2009, Master Randolph won 1st Place in the Black Belt Instructor Fitness Competition, beating over 20 black belt head instructors from around Colorado.

On March 2nd, 2013, he was inducted into the USA Martial Arts Hall of Fame as Martial Arts Master of the Year. On March 18th, 2017, he was inducted again as Master Instructor of the Year. He has been Head Instructor of Boulder Karate since 2003, loving every minute of it!

The father of two wonderful young boys, Master Randolph understands parents’ needs for their children through the martial arts. He also enjoys training weekly with his lovely wife, Nikole Randolph, who is also a Black Belt with over 10 years of training.

When he’s not practicing Kempo Karate, Master Randolph enjoys testing his grit and appreciating Colorado’s beautiful mountains. He has climbed all of Colorado’s 14ers (mountains over 14,000′), scaling over 1/3 of them in calendar winter. He also leads Boulder Karate’s yearly Climbing For Cancer hikes, bringing dozens of Boulder Karate students and parents to the summit of eight 14ers so far, having raised over $32,000 for cancer research. Master Randolph applies the discipline he has learned through the martial arts to physical challenges, pushing himself in pursuit of the highest achievements, having run two Spartan Ultra Beasts and recently completed the 48-hour GORUCK HTL (endurance event led by Special Forces).

Today, Master Randolph holds the rank of 6th Degree Black Belt, and is committed to helping the community of Boulder experience how the martial arts can change their lives, inside and outside the dojo!



Sensei Kaley has been studying the Martial Arts since she was a child. She first achieved her Black Belt in Tae Kwon Do, then switched to Kempo over 10 years ago. She has been continuing her study of Kempo ever since. Sensei Kaley currently holds the rank of 4th Degree Black Belt in Kempo, under Master Randolph and Grandmaster Brassard.

As far as competition and demonstrations go, Sensei Kaley is a veteran. She has won trophies in state-wide and national tournaments, and has performed Martial Arts demonstrations at countless events, including a Denver Nuggets game.

Everyone loves Sensei Kaley. Her passion for the Martial Arts never seems to relent, whether she’s training or teaching. She is one of the most creative instructors around, and enjoys challenging students of all ages with her new drills to keep training fun year-round.

Parents also appreciate Sensei Kaley because she intuitively knows how to lovingly deal with whiny kids. If a child is trying to get out of doing their Karate class, Sensei Kaley is often able to work her magic and inspire the child to want to hop in, and they love her for it in the end!

Kids, teens, and adults of all ranks respect Sensei Kaley because she is knowledgeable, sincere, friendly and fun! It’s no surprise she has won multiple Instructor of the Year awards.




Sensei Jerry started studying martial arts as child and fondly recalls those days as both difficult and invaluable. “I was smaller than most children my age, so traditional sports were difficult for me. When my parents enrolled me in Tae Kwon Do, we found that I had some aptitude for it despite my size. I enjoyed the practice, despite how tough it could be at times, which developed my confidence both inside and outside of the school.” Since then, Sensei Jerry has studied kung fu styles, Tang Soo Do, and a variety of weapons.

We asked him for a quick example of a challenging training story and Jerry chuckled. “One day as a boy I had accidentally stepped on a bee. It stung me, leaving my foot a bit swollen, but I still went to Tae Kwon Do class. The master of the school found out why I was limping a bit and decided to make that day focus on running jump side kicks to a hanging bag and footwork drills. I had to adapt how I moved to keep up with the class and that taught me to be more flexible with how I approach challenge.”

When asked what he likes most about martial arts as an adult, Jerry said he finds teaching students quite satisfying. “I remember what it’s like to have a teacher who encouraged me to push myself and the surprise I felt when I found that I could overcome limitations I previously had. Now, I find myself making sure to challenge and encourage students that I teach, so they feel that same sense of growth and accomplishment.”
