Sergeant Whitehead retired from the Maryland State Police in 2010, which then provided ample time to pursue his martial arts training – returning to his once-nemesis – Master Barry Smith. He trained with his loyal friend until Master Smith’s passing in 2019. Sensei Smith had taken his 50 years of Isshinryu training, combined it with 25 years in law enforcement, numerous street encounters, and developed a style of survival. It was mean – brutal - full of many tricks and deceit – and was downright nasty. Carrying on Master Smith’s tradition, Darron routinely trains defensive tactics to police academy cadets. He is also a certified Krav Maga instructor.

 

In his retirement, Darron has pursued his lifelong passions of entrepreneurialism and giving back to the community. He currently owns his own real estate firm, property management company, rental properties, and serves on numerous boards such as the Police Review Board, Emmanuel Weslyn Church Board, and Hebron Bank Board.

Darron Whitehead

 

Sensei Darron Whitehead is a 6th degree black-belt in Isshinryu and a 6th degree black-belt in Kenshido (The Humble Person’s Way), a style he founded by combining techniques from all of the styles he has studied throughout his 35 years in the martial arts. Darron founded the Salisbury School of Martial Arts, and actively serves as its primary instructor. He has also enlisted his sons to expose the class to Jiu-Jitsu training one class per month.


Sensei Whitehead began his martial arts training in Shorinji Kempo, where he earned a 2nd degree black-belt prior to pausing his training to attend the Maryland State Police Academy. While in the academy, Sensei Whitehead’s training took a turn – as his Defensive Tactics (DT) instructor was Master Barry Smith, a 9th degree Isshinryu black-belt under Master Toby Cooling. After becoming a trooper, Darron returned to his hometown. Having been inspired by his nemesis DT instructor, Darron pursued Isshinryu, and earned his black-belt in 1991.

 

Coming from a rural area, “everyone knew everyone,” especially in the police and martial arts worlds. It was during this time that Darron connected with Hal Chernoff, a professional boxing coach. Hal lead Darron through several amateur boxing matches. Through his amateur boxing fights, Darron connected with 3-time World Kickboxing Champion,
Roni Lewis out of Baltimore. Darron spent several years diligently training kickboxing with Roni, until ultimately Roni retired.

Scott Shamblin


Master Scott Shamblin Ku-dan (9th degree black belt) began his training in Isshinryu karate on November 17, 1973, under the instruction of Master J.C. Burris in Athens, Tennessee. His study continued with Master Angi Uezu, first in 1987 in Fredericksburg, Virginia, then in 1993 as Mr. Shamblin traveled to and trained in Okinawa, and again in 1994 in Cleveland, TN.

 

Mr. Shamblin was also a long-time student of the late Allen Wheeler of Powell, TN and was named by Master Wheeler, before his passing, as his successor. In competition he was the first person at the Isshinryu Hall of Fame Tournament to ever win first place in Weapons, Kata, and Kumite as well as Grand Champion in Kata, Weapons and Kumite.

 

Mr. Shamblin was the youngest black belt to win the Kata Grand Championship at the Battle of Nashville. He was the overall champion in weapons, Kata, and Kumite for the Tennessee Karate Circuit in 1990. At the 1999 A.A.U. Nationals, he received the bronze medal for Kata, silver for weapons, and brought home the gold for fighting. He was undefeated in fighting in 1999 at the state, regional, and national levels.

​​

Outside the competitive arena, Mr. Shamblin and wife Ruth Ann had the honor of participating in the Isshinryu Karate demonstration, lead by Master Angi Uezu, during the Restoration Festival of Shuri Castle in Shuri, Okinawa.

 

Mr. and Mrs. Shamblin taught the Cleveland State Karate Program (credit and non-credit classes) and owned and operated Shamblins’ School of Karate in Cleveland, TN from 1990 to 2009. During that time, they hosted the Cleveland Karate Challenge open tournament for several years.

 

As an instructor, Mr. Shamblin believes in strong Isshinryu basics and practical applications of kata movements. His other studies have included ToriteJitsu, Sport Jujitsu, Tae Kwon Do, and Tai Chi Chuan. Shamblin believes in being a student of the martial arts and studying them in depth to help with his understanding of Isshinryu, but never to replace it. It is his firm belief that Isshinryu Karate is a complete system of self-defense, and that if you truly understand it, you do not have to embellish it.

 

Shamblin currently serves as President of the International Isshinryu Karate Association (IIKA), secretary/treasurer for the Traditional Okinawan Karate Association (TOKA), and President of the Isshinryu Hall of Fame (IHOF). He also served as past President of the Okinawan Karate-do Union (OKU). To earn his rank, Mr. Shamblin provides lessons to advanced students, instructors, and dojo owners. He serves as advisor to the Bryan College Martial Arts Academy (BCMAA) karate program in Dayton, TN and teaches the Kobudo Instructor Certification courses for the IIKA.

 

Mr. Shamblin lives in Ocoee, Tennessee with his wife Ruth Ann (8th degree black belt).
