At age 16, I decided to undertake a plumbing apprenticeship, providing myself with the opportunity to work in the field with Streater Plumbing. A year later, at the age of 17, I embarked in the sport of Boxing as a hobby. Boxing and myself fit seamlessly and at the age of 18, on my birthday, I made his Amateur Boxing debut.While completing my plumbing apprenticeship, and enrolling in night classes to become a licensed plumber, my boxing ability developed immensely. At age 20, I won State titles and also turned Pro.At the age of 23, I forfeited my full-time employment, after receiving the opportunity to fight for a WBC (World Boxing Council) Youth World title.In 2015, my rapid success attracted Australia’s most renowned and respected figures in Boxing – Graham Shaw. Under Graham’s expert coaching, he advised Jack in his Round 4 Knockout match against the Chinese Champion. This match rewarded Jack with the WBC Youth and OPBF welterweight title. Fast forward to 2018, I have headlined three Johnny Lewis Fight Nights at The Star, Sydney and travelled, trained and fought around the world.I also completed my Personal Training Certification in 2016 and launched Brubaker Boxing, which is designed to assist, support, maintain and boost Jack’s career in Boxing.On the back of a huge win against Tyrone Nurse (35W-3L) in May 2018, I was approached by Mike Altamura who is an international consultant for MTK GLOBAL. MTK GLOBAL is the worlds foremost boxer management company and I have just signed a 3 year contract with MTK. This partnership will help take my career to the next level as MTK have connections with the right people who put on the big shows and big fights.
