Born in England in 1963, Richard Amos sensei began karate at age 11. Occasionally teaching from as young as 15 he was invited onto the KUGB Junior Karate Team at 18. By the age of 23 he had competed in England and Europe gaining many Gold, Silver and Bronze medals in numerous championships.

After a two-year sojourn in New York, he went to Japan to train at the headquarters of the Japan Karate Association and stayed 10 years. During that time he completed the 3-year instructor's program of the JKA (only the 2nd Westerner ever to do so in its 50-year history), placed second or third in the All-Japan Championships several times (no non-Japanese had ever reached the semi-finals before), taught many classes each week over a 6-year period in the headquarters of the JKA (another first) and opened his own school in the heart of Tokyo.

In 2000 Amos sensei moved to New York again, this time as an established professional karate instructor with an international reputation. He is currently the chief instructor of the World Traditional Karate Organization (WTKO) heading its instructor program and teaches everyday at the headquarters dojo on 71st Street and 1st Avenue in Manhattan.

Yanti Amos sensei was born in Australia in 1964 and began her martial arts journey with Taekwondo during her years studying at Monash University in Melbourne in the 1980s. She quickly rose to leadership roles, serving as club captain, and eventually President of the Monash University Taekwondo Club, while competing in tournaments across Australia.

A lifelong athlete, Yanti also competed in Badminton and tennis throughout high school & university and played polo at a global level for over a decade from the mid-90s during her time in Asia. She balanced these athletic pursuits with her 20-year career as a corporate lawyer, working in Australia, Indonesia and the UK. It was while working in London in 2003 that she transitioned to Shotokan karate, training under Ohta sensei at the Budokwai.

After marrying Richard in 2008, she joined him in New York City and founded Earth Yoga NYC, located in the same building as Richard's dojo. The studio flourished until its sale in 2019, allowing Yanti to focus on merging her extensive yoga practice with her deepening commitment to karate. Today, Yanti teaches both karate & yoga at the Honbu Dojo in NYC, and often partners with Richard to lead joint seminars worldwide.

Yanti sensei also serves as the Global Ambassador for the WTKO and heads its Women's Leadership Program, dedicated to fostering growth, mentorship, and empowerment for all, within the global karate community.
