Dr. Nathan Chrimes (Osteopath)

Nathan is an experienced osteopath with a passion for helping people move well and feel their best. Known for his hands-on, personalised approach, he blends structural osteopathy with evidence-based strategies to support recovery, relieve pain, and enhance overall function.

At Matrix Health and Performance, Nathan is committed to delivering high-quality care that empowers every patient to take an active role in their health journey.
Nathan holds a double degree in Bachelor of Applied Science and Bachelor of Health Science (Osteopathy) from RMIT University, giving him a strong academic foundation in musculoskeletal health and clinical management.

He has worked alongside physiotherapists in multidisciplinary settings throughout his career, which has shaped his holistic perspective on rehabilitation, movement quality, and long-term recovery. In 2018, Nathan participated in the SALT Health Solutions program in India—an initiative that broadened his perspective on global healthcare and strengthened his commitment to community-focused care.

Nathan has also worked with elite athletes across the AFL and A-League, designing performance-driven treatment plans aimed at optimising physical conditioning, enhancing recovery, and reducing injury risk.

Clinically, Nathan has a special interest in headache management and postural dysfunctions, particularly in those with desk-based or sedentary work habits. He’s passionate about educating patients on ergonomics and offering practical solutions to reduce strain and prevent chronic issues.

Outside the clinic, you’ll find Nathan playing cricket on weekends, fitting in a round of golf when he can, and spending quality time with his dog.
At Matrix, he brings together clinical expertise, practical experience, and a caring approach to help you move better, feel better, and perform at your best.

Dr. Nicholas Giovas (Osteopath)

Nick is a registered Osteopath who graduated from RMIT University in 2017, with a Bachelor of Health Science and Bachelor of Applied Science (Osteopathy).

Nick’s style of osteopathy pays a particular focus to the nervous system and the changes that occur within that system over time, as well as a strong focus on the uniquely human trait of bipedal walking and running. He believes that a deeper comprehension of these neurological changes, coupled with a keen focus on the nervous system in rehabilitation, results in enhanced patient outcomes.

Striving to maintain a holistic outlook, Nick is determined to discover the root causes of any symptoms that arise. Nick's holistic approach has further evolved, venturing into the world of functional medicine, where he's developed a keen interest in blood chemistry, gut health and health optimisation.

Continually learning, Nick is committed to staying abreast with the most recent research to inform his treatment and rehabilitation strategies. His particular interest lies in treating chronic back pain, gait-related dysfunctions, neck and shoulder pain, and, more recently, addressing gut health issues and optimising hormone balance.

With a strong emphasis on rehabilitation, Nick encourages his patients to actively participate in their care through prescribed exercises. His goal is to initiate long-term physiological changes and prevent recurrent injuries, thus crafting sustainable wellness and optimal health.
