ABOUT ONE80 HEALTH
Helping People Adapt, Recover, and Perform — at Every Stage of Life
At ONE80 Health, we believe health is not the absence of symptoms, it is the ability to adapt.
Adapt to physical load.
Adapt to stress.
Adapt to injury, illness, and the demands of modern life.
For over two decades, our Toronto-based clinicians have supported individuals and families through every stage of life, from early development to high performance, and from acute injury to long-standing, complex conditions. Our work is centered on helping people restore capacity, resilience, and confidence in their bodies.
We don’t chase symptoms. We build systems that function.
A Thoughtful, Integrated Approach to Care
At ONE80 Health, we view pain, injury, and dysfunction as signals, not isolated problems.
Your body is constantly responding to multiple forms of stress: physical load, emotional pressure, environmental demands, recovery deficits, and lifestyle factors. When these stressors exceed your ability to adapt, symptoms appear.
Our role is to identify where adaptation is failing and why.
We assess how you move, how you recover, how you manage stress, and how your nervous system and tissues are responding over time. Care is then structured to reduce unnecessary stress, restore capacity, and progressively rebuild resilience.
This integrated approach allows us to treat both acute injuries and long-standing conditions with clarity and intent, not guesswork.
Founder’s Perspective
ONE80 Health was built from a simple but often overlooked truth: the body does not break down randomly.
After more than two decades in clinical practice, I’ve seen that lasting health is not achieved by chasing symptoms or applying isolated treatments. It comes from understanding how stress, load, recovery, and behaviour interact over time.
My role, and the role of our team, is to help people make sense of their health, not feel dependent on care. We focus on restoring confidence in the body, building capacity where it has been lost, and guiding people toward decisions that support long-term resilience.
This clinic exists for people who want clarity, not quick fixes, and who value thoughtful, principled care.

Who We Are Best For
ONE80 Health is best suited for individuals who:
Have unresolved or recurring pain despite prior care
Are dealing with complex or layered issues (injury, stress, workload, recovery)
Want a clear plan, not disconnected treatments
Value understanding their body and participating in their care
Are proactive about long-term health, performance, and aging well
We may not be the right fit if you are looking for:
a one-visit fix
purely passive treatment
or care without personal involvement
We believe the best outcomes come from collaboration, consistency, and informed decision-making.
