Lesley Baker

BHSc (Comp Med), MANTA
Naturopath, Herbalist, Nutritionist
The Hawrelak Gut and Microbiome Clinic - Associate

Lesley is a degree qualified naturopath who has been in clinical practice since 2002. She has extensive experience treating many health conditions in clients from around the world, from birth to the elderly. Over the past 20+ years in practice, Lesley has amassed extensive experience across many health conditions, and she particularly enjoys supporting those with gastrointestinal conditions; autoimmune diseases; skin conditions; genitourinary conditions; and dysbiotic microbiomes of the gut, vagina, and bladder. Lesley also enjoys working with children.


Lesley is passionate about helping people break free from the often-debilitating symptoms caused by dysfunctional bowel patterns and gastrointestinal disorders and their effect on quality of life. When she discovered Dr. Hawrelak's approach to gut health and microbiome manipulation several years ago, she was very excited to implement his approach of nurturing the microbiome and addressing the underlying causes of dis-ease without further risk to our wonderful world of microbes.


Since then, Lesley has completed Dr. Jason Hawrelak's trainings in Naturopathic and Functional Medicine Approaches to Gastrointestinal Disorders and Advanced Microbiome Manipulation and is a dedicated member of The Hawrelak Gut and Microbiome Clinic Team. This training has further fuelled Lesley's passion for the world of microbes and how they can both positively and negatively affect an individual's health, not just at the gut level, but in all areas of the body and disease states.

Lesley welcomes the challenge of finding the underlying cause of her patients' disease, and understands that this is a requirement to effectively address symptoms and bring about permanent resolution. To elicit positive, long-term results, Lesley takes an extensive case history and utilises appropriate functional pathology testing and microbiome analysis, enabling her to establish the cause or origin of the dis-ease or pattern of ill health. She then tailors a personalised combination of herbal and nutritional medicine prescriptions, and dietary and lifestyle changes (think food as medicine!) to aid in healing.

Lesley strives to educate her clients so that they comprehend why their symptoms have developed; she then works to help them understand their treatment plan, so that they may be engaged and invested in their own healing then in preventing the return of symptoms. She is thrilled when clients report that they can leave the house without looking for the nearest toilets; are able to eat with friends and families again, or simply without fear or pain; or feel physically comfortable and are not constantly aware of their tummies. Lesley also gets a thrill out of providing healthy, alternative tasty treat recipes that are part of the treatment.


Lesley believes in education as a means to prevent future states of dis–ease, and would love to see health and nutrition taught in the school curriculum from prep to the end of high school. Lesley has a passion for learning and is continuously updating her skills and knowledge and keeping up to date with the latest research. She has a vision to one day teach in the areas of Naturopathy and Herbal Medicine.


As a mother of five and with autoimmune conditions herself, Lesley understands the challenges that can come along with the journey back to health and feels privileged and grateful to be able to help others on that journey.


Outside of the clinic Lesley works enthusiastically to protect nature and the environment in any way she can, is passionate about her gym workouts, and loves yoga and Zumba (the perfect combination of two of her favourite pastimes - dancing and exercise). In short, she loves food for both the body and soul!
