Besides working full time helping students and teachers (and organizers) with various aches and pains all day Friday and Saturday, he can be found outdoors early in the morning for anyone who would like to join him for TaiChi practice.

Greg Postal

Kyu Kumite is something we learn as white belts, use to test for green and brown belts and then largely forget as black belts in favor of other, more “realistic” training. In fact, these (supposedly) simple exercises, practiced correctly can contribute more to self-defense readiness than many hours of sport oriented sparring. Learn ways to teach these often maligned drills in your dojo to minimize rote repetition and hone your students’ abilities to utilize Uechi techniques and principles in real world environments.

Saturday JuniorFest

Fred teaches Goju, Matayoshi Kobudo, and Feeding Crane at his dojo in Waltham, MA.

Mario Rizzo, Esq.
Personal defense is a prime reason that people study the martial arts.  Preparing to defend yourself requires more than the study of techniques and the physical training of one’s body.  It requires studying and understanding the principles of combat and preparing mentally to implement them.  Among these principles are decisive action, aggressive action, and speed.  The Uechi-ryu practitioner can achieve this goal within his usual course of study by incorporating changes in emphasis in the performance of kata, kumite, and exercises.  My session will explore these changes, primarily through the use of kata.

John Thurston
John ThurstonWe are very pleased to learn that John has agreed to teach at this year’s SummerFest. He will be working with new students who want an indept understanding of our primary kata, Sanchin.”The fighting Heart of Sanchin” . It would be for beginners. He will include “Rooting skills for Uechi Practitioners”.

David Kelley has been a practitioner of Uechi-Ryu Karate since 1974.  He is a senior student of Sensei Buzz Durkin and holds the rank of 8th Dan.  His presentation will focus on various practical applications of circular movements found in the Uechi-Ryu kata; specifically as they relate to locks, holds, joint manipulation, and the movement and control of an individual. 


Marjorie Swift 6th degree Black Belt

Marjorie Swift
6th degree Black Belt

Mention self-defense & the average martial artist reviews all the techniques he or she has practiced many times. Followed by the statement: This won’t happen to me.”
In this seminar, we will explore the statistics, starting with “Most crimes are committed by someone you know, not a stranger in a dark alley”.
The most important skill you can cultivate is “awareness”. Learn to trust your 6th sense. Learn the difference between assertive & aggressive. Most people do not recognize a comment or “come-on” as the test of your receptiveness.
We will act out some scenarios with a partner. Practicing a realistic response to a actual or perceived threat is much like practicing your karate moves.
We will conclude with the discussion of physical techniques.
