Agile HR Transformation, HR Interim Manager, Transition Coach
"If you want to leave your mark, you need a profile."
Kristina Knopp is an experienced transformation consultant with over 25 years of experience in international organizations. She specializes in talent management, leadership and change - from strategy to implementation. Kristina has a deep understanding of corporate culture, processes and people - especially in the SME context.
She studied work and organizational psychology in Nottingham and London, later adding business administration by distance learning - and has continued her education: as a trainer, coach, agile coach, scrum master, most recently with programs at INSEAD. Her career has been international, with stints in Denmark, the Czech Republic and England. Whether managing personnel in a merger, setting up a site or relocating production to Eastern Europe - change was never an exception for her, but part of her everyday life.
At the age of 30, Kristina had already merged two companies as Head of HR. She later held global responsibility up to VP level - with up to 250 employees in her reporting line. She has been working independently as a consultant, interim manager and coach since 2019. She changes perspective as required: from internal to external, from strategy to implementation, from team to individual.
Kristina not only brings concepts to the table, she also gets stuck in. She knows how leadership really works today - with all its areas of tension and possibilities. And she has experienced what makes talents grow - and what makes them fail.
