Coach Oscar

My name is Oscar van Rooij and I am co founder, coach and facilitator of the Health Mastery Academy.

 Over the last 25 years I have supported thousands of people on their personal development.

Following this program I lost 14 years of metabolic age, 11.2% body fat, 4 litres of visceral fat and added 7kg of muscle. 

I am looking forward to supporting you on your health journey.

Oscar van Rooij

Coach Suzanne

I am Suzanne, Co-founder of Health Mastery. I also co-founded The Green Woman, creating natural alternatives that are safer for our health. 

My focus is nutrition and holistic ingredients and practices.

Following the plan I lost 10kg (22lb), 11% body fat, 2.5 litres of visceral fat, added 1.8kg of muscle and smashed my energy levels. 

Thank you for being here, I am excited to support you, and share your journey.


What our customers say

Oscar is an extraordinary personal development coach. He has a broad knowledge of what makes people actually do what they do and he is also knowledgeable about why people don’t do the things which they say that they truly want but for some reason don’t do. 

Oscar is a master at making you confront yourself and he turns a microscope on making you discover what prevents you from reaching your personal benchmarks. I have been working with him for quite a while now and I have seen a marked improvement and made real progress in fulfilling my goals.

I have so enjoyed working with Suzanne over the past 6 months and feel that the experience has really helped me to get back on track with my healthy food intake.
Reminding me about the benefits of high protein and high fibre has been an absolute game changer with my body and with my daily life, as I feel I have far more energy and I’m more focused on tasks.
It’s also really reassuring to have somebody that you know is your wing woman and wants the very best for you and she is just as excited as you are to see good results.
I have gained muscle and lost inches of visceral fat around my waist line, which is so important at my age, and I keep as healthy as possible because I want to be there to see my granddaughters grow up and flourish!

Lisa-Ann Dickenson

I worked with Oscar for about three years and found him to be one of the most genuinely motivational and inspiration people I’ve had the pleasure of meeting. Oscar ran a number of training sessions in our Company; some needed to develop their skills, some needed to acquire skills and some had become weary of their day to day lives, losing confidence in their ability. Oscar re-woke what was great about them, gave them back that lost confidence and inspired them to be the best they could be or wanted to be.

I can’t thank Suzanne enough for all the help and support she has given to me on my weight loss journey.
When I met Suzanne it felt like such a huge mountain to climb and I was very emotional about how unhealthy I felt and
how much weight I had to lose. Nothing seemed to be working for me.
Suzanne helped set out goals and a clear plan for me to
follow. Her enthusiasm and faith in me spurred me on and when I started seeing results and changes in myself I just wanted to keep it up. Thank you so much!

Oscar is perceptive, wise, compassionate, and honest. I really appreciate the ways he has helped me to unleash my better self and the power within. Thank you once again Oscar for facilitating my breakthrough.

Oscar has an inspirational character and the ability to change the energy of a whole room. I am very grateful for having attended his event last weekend. He has given me a lot of tools to put in place to improve my life and my experience. His energy levels are through the roof and he knows how to pass that onto his audience.

Toni Leach, owner at Toni Leach Fitness

Oscar & Suzanne are just amazing. Suzanne has been helping me with my diet for 5 months now. Following Suzanne's advice I now have much more energy and also have considerably more strength. 

I find the weekly 1 hour group zoom coaching keeps me on track which also includes Oscar input. He helps explain how I can change my behaviours and thinking to achieve my goals. I am having some extra help from Oscar on his life coaching which is transformative, thank you guys. 

My journey is just starting and it's so exiting! I couldn't recommend them both enough.
