Tania Schnuppe
ATC Cleansing Coach

Breast Cancer was a big shock and a scare to me and my friends and family but it was also a gift. I was able to find the motivation to sink my being into finding the ultimate way of life for longevity. I discovered juicing as the core component and route to a healthy body and so the journey began.

I now practice Heath Coaching and use Hypnotherapy as an added tool for those who wish to try it and to give back that motivation that was so important in my own recovery. I am also a counsellor to newly diagnosed Breast Cancer patients.

I have a special interest in the role of nutrition, sleep, meditation, self-hypnosis, exercise, stress management and my mission is to emphasise on healing from the root rather than to mask symptoms with medication.

Karen Ziervogel
ATC Certified HBR Coach

I have a powerful internal locus of control, which, more often than not, has me challenging convention when a matter is important to me. I am tenacious and fearless in pursuing my goals – especially those in the face of society's 'you can't do that' beliefs.

I am a fighter – literally and figuratively. I box at FightClub SA for my physical fitness and I battle with myself to become better at being ME. I believe in the Law of Attraction with a healthy dose of the Hustle thrown in. I believe that what we think about, we bring about – impossible though – without tenacious effort and a strong work ethic!
