Paul practised as a lawyer for over 30 years when he developed severe obstructive sleep apnoea. His health was poor until he learned the Buteyko Method. By learning to breathe almost exclusively through his nose and slow down his rate of breathing his symptoms decreased significantly. In 2014 he wrote a seminal account of his journey and published "Breathless Sleep...no more. A compelling case study." This health improvement resulted in him changing his career to become a Breathing Retrainer. He trained with Patrick McKeown and obtained further mentoring and clinical experience from Paul O'Connell from the Buteyko Institute of Breathing and Health. In 2018 Paul published a 2nd edition of his book with a significant contribution from Patrick McKeown. Patrick also wrote the Foreword to the 2nd edition. Paul trained with the Australian Institute of Applied Mindfulness and was certified as a Practitioner in 2019. Paul teaches a Mindful Buteyko Breathing Course.
