Meet Our Instructors


Michael Capurso

Sensei Mike Capurso has been with the RKA family for 18+ years, starting his martial arts journey when he was 6 years old. He studied under his wonderful teachers and former owners of RKA, Shihan Ken Domney (6th dan) and Renshi Pat Domney (5th dan) who taught Shukokai Karate developed by Soke Shigeru Kimura (10th dan). At the age of 13 he was invited to join the Leadership Team to assist the
instructors. In 2010 at age 15, Sensei Mike earned his black belt alongside his younger brother,
Sensei John. At that time, he was offered the position of Joshu (assistant instructor). In 2015, Sensei Mike was promoted to Deshi (teacher-in-training). In 2016,
Shihan Ken and Renshi Pat had promoted him to Sensei before they retired. Renshi and Shihan had
passed the school on to Master Lau, who helped us continue our traditions and goals of teaching
children, teens and adults self-defense while instilling self-confidence in a fun, family friendly
environment. From 2016 to 2020, Sensei Mike would train under Master Steve Smyer (5th dan) and learn many new techniques and styles along the way. Today Sensei Mike is one of the head instructors at Ridgewood Karate Academy and is currently working on earning his 4th dan.

Sensei Roosevelt Gonzalez began his martial arts journey at the age of 5 years old. He has attained his black belt in karate at the age of 13 years old. He holds a strong background in standup Muay thai and MMA as well as a blue belt in jiu jitsu. Roosevelt has been teaching classes for over seven years and excels at balancing between teaching, training and managing our facility. Roosevelt's main goal is to make sure all his students progress and strive towards black belt excellence. Keeping everything running smoothly behind the scenes as well as instructing students in the children's martial arts programs, Roosevelt is known for his high enthusiasm and passion towards martial arts.


Arnold Lau

Master Arnold Lau trains and competes internationally for over 35 years. With championships along the US East Coast, Europe, and Asia, Master Lau trained and developed his skills in many martial arts disciplines. He was the captain of the Rutgers Martial Arts team from 1988 til 1992 and served as head instructor at Rutgers from 1993 until 2004.  Master Lau remains active with the Rutgers community by funding college scholarships and teaching as a part-time lecturer in Computer Science.

Master Lau saw an opportunity in Ridgewood Karate Academy to continue a tradition of developing the martial artists of the future. Teaching at RKA is an opportunity to instill some of the attributes that helped Master Lau achieve his personal development goals.
