Anastasis Tzanis

After serving in the special forces for 1 year as a paratrooper, working in investment banking for 6 years as a currency derivatives trader and picking up a few more dopamine-driven hobbies along the way; in January 2010 I started practicing yoga and studying nutritional therapy. In 2014 I founded HealthConsc, an online clinic offering nutritional advice for patients with cancer and autoimmune conditions. Alongside this I started teaching yoga. Since 2016 the focus of my practice has become the optimisation of metabolism. Patrick McKeown’s work has played a pivotal role in my understanding of human physiology. In 2017 I started implementing the “Oxygen Advantage” techniques in both my yoga teachings & clinical practice. My place of practice is Light Centre Moorgate. 114 London Wall, London, EC2M 5QA.
