Top presentation topics 2024Presentations / Keynotes

Dr. Sonja A. Buholzer’s presentations and keynotes (standard German and English) aim to provoke reflection and rethinking, looking further than the end of your nose. Rethink, prioritise and identify multiple solutions.

From decades of business practice, 1000’s of consulting hours and countless valuable discussions with CEO’s, business leaders and managers, including many women, management we confront and challenge management taboos, we speak in plain language and present innovation: everyone who participates in thinking, discussing and acting will be able to take home suggestions and strategies to guarantee personal success from every presentation.
