Denzel Marthinussen

BSc, MClinAud.

From a young age, I knew I wanted to make a meaningful difference in people’s lives within the medical field. My fascination with physiology—particularly the sound and balance organs—grew out of my deep connection to music, a constant presence in my life. Realising how much I took hearing for granted sparked a desire to help others preserve and rediscover this incredible sense, and my curiosity for emerging research in audiology has fuelled my passion ever since. Before joining Knox Audiology, I completed my undergraduate studies, majoring in Physiology and Pharmacology, captivated by sensory systems and the innovative solutions that address their imbalances. Alongside my studies, I spent years playing and performing music at gigs across Melbourne, which only deepened my appreciation for sound and its impact.

For me, being an audiologist is all about the connections I build with people. I cherish the personal relationships that form as I guide individuals through their hearing health journey, diagnosing challenges and providing solutions that help them reconnect with the people and moments that matter most. Outside of work, you’ll often find me on the soccer field, soaking up the game’s energy and camaraderie, or sharing a laugh—whether it’s cracking jokes with friends, family, or my partner, those light-hearted moments keep me grounded. And when it comes to my favourite sound? Nothing beats the soulful rhythms of South African jazz songs, paired with the warmth of genuine laughter—it’s a combination that never fails to lift my spirits.
