Martina Gleissenebner-Teskey studied ecology, psychology and communication sciences and is a systemic coach. During her studies she was internationally active as a model and as a representative of Austrian environmental NGOs. In 1996 she launched the „Charisma concept“ for the development of personal talents and thus started an international career as a trainer, coach and lecturer. The book on the concept was published in 2017 and was reprinted in a revised and extended version in 2023. Gleissenebner-Teskey lived in Milan and Monte Carlo, where her daughter Lou-Anne was born. On her 50th birthday, she applied independently of Lou-Anne to one of the leading German TV-shows, Germany’s Next Tomodel by Heidi Klum, and was the first best ager to win third place. When she got back into modeling, she soon returned to her sustainability roots. With her ambitious project WALK4FUTURE, she has come full circle, using her increased popularity to promote solutions for a sustainable future of fashion as a model, speaker and activist.
