Welcome, I am Fin Mackenzie

I have opened this clinic on Sydney’s Northern Beaches because I believe Natural Therapies is the only way to combat the huge burden that preventable disease is placing on our Medicare System. And because I feel modern medicine does not have all the answers, we can work in a complementary way alongside Orthodox Medicine. People need help, support and guidance to reach their best potential.

Mums are the ones who take care of everyone but who look’s after them? They are also the ones who take responsibility for their children’s health, give medicines and organize after school activities. Many mums work and juggle housework with childcare. They are the main users of natural therapists in Australia. Too many children are treated poorly by doctors, stuffed with antibiotics and given drugs for behavioural problems. We want to educate mums about the benefits of changing the diet and adding minerals and supplementation and the huge improvements you can see when you do that.

Autism, ADHD and learning difficulties are on the rise. 1 in 59 children are now diagnosed with Autism. 1 in 9 Australians have asthma – around 2.5 million. Food allergy occurs in around 1 in 20 children and in about 2 in 100 adults ( Eczema (also known as atopic dermatitis) is most common in infants where it occurs in around 1 in 5 children under 2 years of age. Modern medicine is not able to cope with the massive increase in these type of chronic conditions or allergic diseases – it’s an epidemic! This is where natural medicine is very effective. We may be able to help!

Our approach is not to suppress symptoms but to work with the bodies natural healing response and we do that with evidence based supplements and often short term dietary changes.

Many mums need support and advice to enable them to stick to a course of natural treatment, and education to enable them to succeed at their chosen course of action.

Let’s not forget Dads in the equation for they will often be carrying the weight of the world on their shoulders…they may be working full time and missing out on their children growing up, or are taking the responsibility for providing financial support. Or maybe they are providing the main caring role as their other half has gone to work full time. Modern family dynamics have changed so much and therefore men’s roles have too. Often they are not prepared and not equipped to deal with those changes. Families may have been split through divorce, grief or addictions. Dads may be suffering myriad health issues from diabetes, adrenal exhaustion, hay fever, high cholesterol to high blood pressure.

If this sounds like you and you would like to make some positive changes in your family’s lifestyle today then give us a ring today!

We have a 24 hour answering service and will get back to you ASAP.

I look forward to meeting you and helping you on your journey towards better health!

Saffron – The Sunshine Herb

Saffron – The Sunshine Herb

Saffron - Crocus sativus L. As we move into the winter months I thought it would be good to talk about a herb that can help bring the summer back.  SAD or seasonal affective disorder is a type of depression that often appears in winter and disappears in summer. ...

“We were struggling with our daughter’s eczema for months before a friend recommended Fin. She took the time to ask all the right questions and prescribed some natural supplements. Within 48 hours, our daughter’s skin had cleared and the supplements she takes continue to keep her immune system very healthy and her eczema and allergies are controllable without any pharmaceutical creams or drugs.”
