With over 30 years of training experience and a lifelong dedication to fitness, I bring real-world knowledge and passion to every session. I’ve walked the walk — including stepping on stage and earning 2nd place in my first bodybuilding competition, the Australian ABF Championships at age 44.

As a father of two, I value being strong, healthy, and a positive role model. I hold Certificate III & IV in Fitness, and draw from a diverse career as a teacher, football coach, and teen counsellor, allowing me to support clients beyond just physical training.

I specialise in working with men over 30 to improve body composition, build strength, and take charge of their health. Whether you’re starting fresh or ready to level up, I create personalised, results-driven programs to help you thrive.
