Sensei Michael Wall

Mr. Michael Wall always wanted to do martial arts, but coming from a small town in Iowa there weren’t too many dojo’s around.  He finally got a chance to train while he was attending the University of Northern Iowa in 1972.  After 2 years of training, he received a brown belt in taekwondo under Mr. Mike Nelson. In 1974, he was working out at the University of Iowa gymnasium without a teacher.  He remembered seeing this big guy working out in the corner who looked really good.  He walked over and asked him if he could train with him.  The big guy (Mr. John Hutchcroft) said, “Sure, put on a white belt.”  This didn’t sound too unreasonable for Mr. Wall who then started training with Mr. Hutchcroft in the Shuri-Ryu system. Mr. Wall received his Shodan under Mr. Hutchcroft in 1978.  When Mr. Hutchcroft moved from the Cedar Falls area, Mr. Wall took over his club.  After a year he realized he needed another teacher, and being in the Shuri-Ryu system it seemed only logical to move to Phoenix, AZ in 1979 to train with the master of the system, Grand Master Robert Trias.  Mr. Wall trained with Mr. Trias until his death in 1989. During his years with Master Trias, Mr. Wall became one of the senior staff at the yearly Trias International seminars held in Phoenix. In 1981, Mr. Wall started Paradise Valley School of Karate in Phoenix, AZ.  Since its inception, Mr. Wall and his school has been extremely active in the tournament circuit.  Paradise Valley School of Karate has always been known for its strong tournament presence producing numerous State, National, and World champions.  Paradise Valley Karate has consistently placed in the top 3 slots in the U.S.K.A. (United States Karate Alliance) and the A.S.K.A. (Arizona State Karate Alliance) which he co-founded in 1994.  And in 1999, Paradise Valley School of Karate placed 1st in both the U.S.K.A. & A.S.K.A. point championships.

Bob McNulty

Mr. McNulty began Karate in January of 1982 and studied Shuri-Ryu until 1992, earning a 3rd Degree Black Belt early that year.  Late in 1992 he began to study Ryū-Te under Taika Seiyu Oyata.  In late 2000 he earned a 5th Degree Black Belt in Ryū-Te. In 2005 Mr. McNulty began his studies of Matsamura Seito Shorin Ryu, being accepted into the system as a 5th Degree Black Belt.

Tom Robbins

Mr. Robbins started his Martial Arts career in 1972 studying Kyokushinkai under Sensei Katz.  Kyokushinkai emphasizes realistic combat, physical toughness, and practicality in its 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 Shori Ryu in 1995.  Mr. Robbins now holds the rank of 6th degree Black Belt in Shorin Ryu. Mr. Robbins was award the small double bladed axe insignia by Sensei John Hutchcroft in April 2008. The double bladed axe is the personal insignia of Master 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 ecclectic 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-Jitsu, 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 for 13 years.  He received his 5th Dan in 2014. 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 his 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
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.

Scott Avery

Mr. Avery is an Arizona native and grew up in the Phoenix area.  He began his self defense training with Sensei Mike Wall at Paradise Valley Karate in Shuri-Ryu in the Spring of 1990.  In 1992 he began the transition, with Sensei Wall, to Ryu-Te Ren Mei under Taika Seiyu Oyata.  Scott has regularly competed in tournaments at all ranks on a local and national level over many years.  In the Fall of 2000 Scott achieved his First Degree Black Belt in Ryu-Ku Kempo under Sensei Wall.  A variety of personal distractions, including work and school and missionary service abroad, have kept him away from PV Karate for a number of years as he continued study of several other systems across the country including Judo, Kempo, Tai-Chi, Tae Kwon Do, and Jiu Jitsu.  He has always come “home” again to PV Karate where he is currently a FourthDegree Black Belt and is studying Matsumura Seito Shorin Ryu with Sensei Wall under Hanshi Phillip Koeppel.  Mr. Avery has been happily married since 2001 and he has 3 young children.  He enjoys reinforcing every day applications of Karate, especially with children, to help improve discipline, self esteem, physical fitness, and adjusting to adversity.

Jack Cannada

Mr. Cannada spent 18 years working with AT&T before starting a full time ministry with his wife in 1985. He & his wife traveled for 15 years across the US ministering to multiple denominations.  Then in 1999 he started The Father’s Fellowship Church in Phoenix, where he is still actively working on Sunday. He got his Real Estate license in 2011 and work with Coldwell Banker Residential Brokerage. Mr. Cannada had some health issues at the age of 65 where he needed to make some changes and working out was one of them. He said "Gym and Treadmill was something I just couldn’t stay with, just too boring." "I met with sensei Wall and asked him how much of the religious overtures do you incorporate with your workout? (As a pastor it was something I didn’t gravitate to). He basically said we do combat and conditioning. That works. My first night of workout was on a Monday, which was sparring night. I went home that night and sat in my pool for two hours. I told my wife I can hardly move, but I absolutely love the workout. I began working hard and my goal was to hopefully reach Black Belt before I was 70. I reached my goal five months after I turned 69." Received 2nd degree May 31, 2014.
