Leesa | Naturopath & Master Herbalist in Perth

The Heart Behind the Clinic

I don't just prescribe medicine; I grow it.

 

My journey into health didn’t start in a classroom—it started in the soil. Before becoming a Herbal Naturopath, I spent 15 years owning and operating an organic nursery, where I learned the language of plants first hand.

Today, as the founder of Oak Tree Herbal Clinic, I merge that deep horticultural wisdom with clinical science. Many of the remedies I recommend are the very ones I have raised from seed in our Western Australian climate, ensuring every bottle is a pure, handcrafted expression of "Seed-to-Bottle" medicine.


Seed to Bottle: A Life Immersed in Herbs

In the harsh summers and mild winters of our Western Australian climate, I cultivate a specialized medicinal garden. I grow, harvest, and manufacture botanical remedies from the resilient species that thrive in our local soil, turning them into potent herbal tinctures and flower essences.

I am constantly researching and trialing new species to expand my clinical dispensary. To me, working with medicinal herbs isn't just a career—it is my life’s work.

I speak to my plants every day, ensuring that every bottle produced at Oak Tree Herbal Clinic carries the pure, vibrant energy of the earth. When you work with me, you aren't just getting a standard supplement; you are receiving a handcrafted remedy born from 15 years of organic horticultural wisdom and clinical naturopathic precision.


Clinical Detective meets Mother’s Heart

Beyond the garden and the lab, my world revolves around my family. As a single mother of four grown boys and a proud grandmother, I understand the complexities of modern family life and the deep drive to protect our children's wellbeing. I know how vital a resilient nervous system is for a happy home.

I combine this "Mother’s Intuition" with high-level science—specializing in MTHFR support, Functional Genomics, and ADHD. I help families stop the guesswork by merging the latest DNA technology with the ancient healing power of the organic botanical medicine I grow by hand.

 

My Mission: Decoding the Brain-Body Connection

I don’t believe in "one-size-fits-all" health. Whether you are navigating an ADHD diagnosis, struggling with MTHFR-related burnout, or feeling "wired but tired," your symptoms are not a mystery—they are biological data points.

My work focuses on Functional Genomics and Nervous System Regulation that standard medicine often overlooks. I specialize in identifying the "first domino"—the primary biochemical or energetic imbalance that, when corrected, allows the rest of your health to fall back into place.


Why I Focus on MTHFR & Methylation

Early in my clinical practice, I realized many clients were doing "all the right things" but weren't getting results. This led me deep into the world of Methylation, Nutrigenomics, and Biochemistry.

I saw how a single genetic variant like MTHFR or COMT could fundamentally change how a person processes stress, clears toxins, and produces neurotransmitters like Dopamine and Serotonin. By specializing in these markers as a Methylation practitioner, I help my clients stop fighting their biology and start supporting it.

 

A Multidimensional Clinical Approach

I blend "High-Tech" diagnostics with "High-Touch" traditional wisdom. In my Perth Naturopathic clinic, we utilize:

  • Functional Lab Testing: Including DNA analysis, HTMA (Hair Tissue Mineral Analysis), and Microbiome mapping.
  • Bio-energetic Technology: Using the AVATAR system to listen to the body’s energetic signals in real-time.
  • Biochemical Precision: Applying targeted herbs and nutrients to bypass genetic "glitches" and restore systemic balance.


Why I Do What I Do

I believe that the best medicine is found where the laboratory meets the garden. I am here to help you and your family find your "root cause" and provide the handcrafted, evidence-based support your body needs to thrive.
