About Me
Yvette Janse van Rensburg is an Award-winning Performance Coach and Consultant who helps individuals, teams, and organisations achieve sustainable high performance. With over 15 years of global experience in leadership development, talent management, and mental performance coaching, she works at the intersection of psychology, physiology, and culture to unlock lasting results.
Her approach is rooted in the belief that to perform at our best, we need to get out of our heads and into our breath. Drawing on the Oxygen Advantage® method, Yvette integrates functional breathing into her coaching and facilitation to help clients regulate stress, sharpen focus, and build resilience under pressure. Breathwork is not treated as an add-on, but as a foundational practice that supports clarity of thought, effective decision-making, and the ability to show up with energy and presence - whether in the boardroom, on stage, or leading teams through change.
Equally central to her work is the role of emotions in shaping culture. Yvette uses tools such as the Emotional Culture Deck to help leaders and teams understand how emotions drive behaviour, influence decision-making, and either enable or block high performance. By combining emotional awareness with breath training, she creates space for individuals and organisations to shift from reactivity to intentional, values-driven action.
Based in London, UK, Yvette works with clients locally and internationally, both online and face to face. She partners with senior leaders, entrepreneurs, and high-achieving professionals, as well as leadership teams and organisations navigating demanding environments. Her work blends breath training with evidence-based performance psychology and practical strategies for wellbeing and career success.
Whether coaching one-to-one, facilitating leadership and team away days, or delivering workshops on resilience and high performance, Yvette equips her clients with tools that extend beyond short-term fixes. Her mission is to help people breathe better, think clearer, perform stronger - creating impact that is both immediate and sustainable.
