Sensei Mike Wall


Mike Wall took his first lesson in 1972 and in 1974 became a student of John Hutchcroft when he was in Waterloo, Iowa. He earned his shodan in Shuri Ryu in 1978.  

In 1979, Mr. Wall moved to Phoenix, Arizona to train with the "Father of Karate in America", Master Robert A. Trias.  Mr. Trias accepted Mike as a student and he became a staff instructor for the Trias dojo.  He trained with Mr. Trias until the Master died in July 1989.  Mr. Wall obtained the rank of roku dan.  In 1981,  he opened the Paradise Valley School of Karate, one of the oldest established karate dojo in Phoenix.

Mr. Wall was inducted into the United States Karate Alliance Hall of Fame in 1990 and has served as the President of the Hall of Fame.  He is also the Southwestern Regional Representative of the USKA and the founder of the Arizona State Karate Alliance


He earned his shodan in Shuri Ryu in 1978 under Mr. John Hutchcroft.  

In 1991, Mr. Wall asked Mr. Oyata if he could train with him and was accepted as Mr. Oyata's student.  He studied with him for the next 15 years, and obtained the rank of rokudan.  He also was awarded recognition as a member of Mr. Oyata's Shin Shu Ho, the highest recognition given by Hanshi Oyata in the Ryu Te system.

In 2006, Mr. Wall came full circle and once again became a student of Mr. Hutchcroft in Matsumura Seito Shorin Ryu.  He has attained the grade of 8th degree black belt or Hachidan.


Sensei Wall is a product of the old karate culture where you work hard and are respectful of those who have gone before you.  

He also believes in giving his students his all.  He regularly says that his greatest goal is to produce students better than him.  He says "It is the greatest compliment to me, to have a student work so hard that he surpasses his teacher."


Tom Robbins


Mr. Robbins started his Martial Arts career in 1972 studying Kyokushinkai under Sensei Katz.  Kyokushinkai emphasized realistic combat, physical toughness, and practicality in ints training curriculum.  These are attributes Mr. Robbins still applies in his Martial Arts training today.  After leaving Sensei Katz' tutelage, Mr. Robbins, over the course of the next three plus decades, studied other Martial Arts disciplines including Goju Ryu, Shori Ryu, Ryu Te, and Shorin Ryu.  In 1989, Mr. Robbins began training under Sensei Wall and received a Black Belt in Shuri Ryu in 1995.  Mr. Robbins now holds the rank of 6th degree Black Belt in Shorin Ryu.  Mr. Robbins was awarded the small double bladed axe insignia by Sensei John Hutchcroft in April 2008.  The double bladed axe is the personal insignia of Master Phillip Koeppel.

Cory Kahabka


Sensei Kahabka began taking Kempo Karate when he was 14 in Burlington, Vermont with Sensei David Quinlan.  Sensei Quinlan was a very eclectic martial artist and stressed to his students that they broaden their focus on learning from different styles, not solely focusing on Kempo.  While at this dojo for 14 years, he studied Ed Parker Kempo, Judo, Brazilian Jiu-Jutsu, Small Circle Jiu-Jitsu, and Wing Chun.  He received his 3rd Dan before moving to Phoenix in 2002.  Once in Phoenix, Sensei Kahabka started studying with Sensei Mike Wall at Paradise Valley School of Karate and has been a student as well as a teacher at the dojo ever since.  He received his 5th Dan in 2011.  Sensei Kahabka enjoys working with both beginner as well as advanced students.  His main focus is self-defense.  His goal is to make sure that all of this students are able to defend themselves on the street in real-life situations.  He also teaches the "Girls on Guard" women's self defense program all over the Valley.

Peter Sangiorgio


Mr. Sangiorgio was born in Brooklyn, New York.  He began his Self Defense training as an amateur boxer at a local boxing gym on Long Island where he boxed competitively for about 1 ½ years before switching to martial arts. His martial arts training began under the private tutelage of a Black Belt from a local Martial Arts School.  However after training for about 1 ½ years, life got in the way.  Mr. Sangiorgio and his wife re-located to Phoenix, Arizona in late 1986.  It was not until shortly after 9/11 that Peter once more began serious training.  In December 2001 Mr. Sangiorgio met his current Teacher Sensei Mike Wall.  At the time Sensei Wall was under the Ryu Te Ren Mei system of Taika Seiyu Oyata.

In October of 2005 Sensei Wall switched systems to the current system of Matsumura Seito Shorin Ryu under the direction of Sensei Phillip Koeppel.  Mr. Sangiorgio embraced the new system and has been promoted by Sensei Wall as follows:

  1. First Degree Black Belt – May 05
  2. Second Degree Black Belt – June 06
  3. Third Degree Black Belt – May 08
  4. Fourth Degree Black belt – May 11
  5. Fifth Degree Black Belt – December 2017

Peter teaches a cardio-kick boxing class every Saturday morning along with an adult basics class. The principles that are stressed in these classes are the importance of basics and fundamentals while placing an emphasis on training with intensity to improve both physical and mental toughness.  Mr. Sangiorgio consistently trains and continues his martial arts education by attending as many of Mr. Koeppel and Mr. John Hutchroft’s seminars as he can. 

Peter is a father of three. His two sons currently train at the Paradise Valley School of Karate.  Peter Jr. and Nicolas are both second degree brown belts respectively.

Mr. Cannada is still training and currently holds the rank of 3rd Degree.
