Hi, I am Mark Postles.

I am the founder of the in8model® and I have a profound curiosity for human beings, their behaviours and what makes them do what they do in the ways that they do them.

This enquiry led me along many paths as I explored what it was to live a genuine and authentic life. I knew that a sustainable existence occurs when people are in integrity with themselves and the world, and as this study continued it resulted in a model that I named the Integrity Model. As I delved further into the brain functions that make us do what we do, I realised that integrity is an innate function, hence the model was renamed to the in8model®.

As a speaker, business coach, professional development expert, chiropractor and author, my goal is to touch hearts and inspire as many people’s lives as I can with my vision of hope for humanity.

The in8model® is a roadmap and a method for navigating this journey from the innermost depths of the cerebral cortex to the outermost reaches of the cosmos.

If you would like to have me speak to your group or organisation, please contact us.

Read more about the team behind the in8model® below. Enjoy your journey. I look forward to connecting with you soon.

Davina Scrowther

The in8Model® Licensed Practitioner and Coach (Master)

Davina Scrowther

Davina is a wellness and business coach with over 25 years of customer service and team management experience.

Inspired by her chiropractic assistant mum and having been adjusted since early childhood, her commitment to the chiropractic industry and community health is deeply ingrained.

Davina saw that chiropractors needed support in identifying chiropractic assistants who could support practitioners in business, communicate health and wellness to the community, and maintain their own enthusiasm and inspiration in chiropractic. So, Davina set out to combine her expertise and passion, which led to the establishment of her own coaching business.

Whilst being mentored by Dr. Mark Postles and coaching clients with Quest, Davina has now served more than 40 practices in either a coaching or recruitment field (or both!); hired well over 120 Chiropractic Assistants, and inspired and trained hundreds more.

Dr Beau Woods

The in8model® Licensed Practitioner and Coach (Master)

Beau is a third generation chiropractor, ABC instructor and coach. Graduating from Murdoch in 2006 and also has a bachelor of commerce, majoring in business management.

He has built and managed a number of businesses using the in8model® framework. The pathway from employee, to self employed, to business owner is one that many dream of but few achieve. Most small business people never progress from ‘owning their job’. Using the in8model®, Beau has successfully built a seven figure health services business that is not completely reliant on the practice owner for revenue generation.

Beau has a wide depth of experience, having built, operated and sold multiple chiropractic practices in the country and city. He currently operates three practices in the south of Perth.

“To me, coaching is about transformation. A coach is someone who believes in you more than you believe in yourself. Its about defining who you are and where you are at currently in your life. Then we work out who you want to be and what your ideal life is. Then its a matter of working towards those ideals.”

He is married with 3 boys, and is living proof that we all have all quadrants and that change is not only possible but inevitable!
