Jay began her study of Goju Karate in 1983 achieving Shodan under Sensei Ray Flores in 1995. After Sensei Flores dojo closed in 1997, Jay began to train under Sensei Mulholland at Daigaku's Westminster Dojo in Central London.

"Goju, like life itself, doesn't come easy and the time spent studying and training should be worth your whole spirit. I have dabbled with Judo and Aikido but have found all these things already within the goju system and there is always more to be found."

Jay was badged Shodan by the Daigaku Karate Kai in 1999. She successfully completed her Nidan Grading in June 2002 and was awarded her Sandan instructor's grade in 2008.
