About US | Tier 1 Training



We empower individuals with knowledge and resources to make informed decisions regarding their health and body

Running Up

Like many companies, Tier 1 came about through the relationship of like-minded people and a burning desire to fill a void in the market.

Our goal is to develop a sustainable, accessible and evidence based approach in addressing the health needs of the community. With that in mind we have synthesised the worlds of medicine, medical research and bio-science to build a framework to create that vision.

Through our travels and various working lives across the fields of research, academia and the health care system we saw that a holistic approach was not being taken which left gaps in the system and boxes unchecked.

Tier 1 was founded with the intent to connect the circle and complete the link. The approach taken is to use scientific evidence to blend the mind with the body and keep everything in natural order.

The company has experts in medicine, nutrition and physiotherapy and we are combining years of experience to deliver a holistic approach to health and wellbeing.

We also wanted to create a fun environment that encourages community participation and social cohesion. We are incredibly excited to go on this journey and would be delighted if you joined us.



Dr Alok Narayan

Dr Narayan, a medical doctor, with a range of experience from working in the emergency department to consulting with elite sporting teams. 

"I see a problem with our health system where we work well in the acute stage of an illness or injury, but a holistic approach is not taken. I joined Tier 1 Training as the foundations around movement, nutrition and community align with my values. If my clients were to see a 10% improvement in these areas, they would see much better results

Dr Radhika Seimon

Dr Radhika, a medical researcher, focuses primarily on obesity, nutrition and weight loss. 

"Working in research for 13 years, I noticed a gap between evidenced-based approaches and translation into practice  Joining Tier 1 Training gives me the opportunity to help implement best practice in nutritional guidance at the ground level"

Tien Nguyen

Tarosh Jacob

Tarosh has been in academia for over seven years designing and teaching courses for psychology, economics and communication.
