Today, Marc Wallert says: „I am happy - not despite, but thanks to my life crises“. That's why he talks so openly and humorously about what most people prefer to keep quiet about: The crises. Because they contain opportunities for development. Always. You just have to find them.


As Manager from the business world he knows the challenges facing companies today. For over 15 years, he led teams and managers through the dynamic business jungle, including at global market leaders such as PwC (consulting), Renault (automotive) and Ottobock (MedTech). He burned, burned out. Today, he passes on what he learned from this - as Keynote Speaker for resilience.

His contribution „Free the hostage within you“ as co-author of the book „A nicer wait“ by Armin Nagel (2023, Lübbe Life).
As survivor of a kidnapping Marc Wallert learned how to deal with extreme stress and crises. He felt the power of resilience first-hand. Thanks to it, he survived 140 days in the jungle unscathed. Protective factors such as acceptance and optimism have proven to be effective survival strategies.
Today he shares his Jungle strategies in his keynotes. This is because he has realized how valuable his experiences were for him and how valuable they can be for other people. He is not interested in describing his abduction, but in sharing his impressive experiences.
Looking back, he says: „My abduction was a serious experience that I wouldn't wish on anyone, but one that I wouldn't want to miss. Because it changed and enriched my life with valuable experience .“ He feels a special appreciation for his life in peace and freedom after having experienced captivity and guerrilla warfare.


In his Book „Strength Through Crises“ Marc Wallert has compiled his personal and professional experience of dealing with crises. „A lifelong dream“, as he says.
As Keynote Speaker for resilience, he carries his empowering message out into the world. As he did as a musician, he loves the big stage just as much as the professional studio. Whether live on stage or virtually - there is a spark between Marc and people. It is these goosebump moments that drive Marc, as they open people up to change within themselves and in the world.
Marc was born in 1973 in Goettingen and is now a happily married father with three children. He loves traveling the world with his family. When time allows, he makes music and scuba dives.
