Christine Walker

Speaker & Coach

Christine Walker is the founder and managing director of PLU Top Assistant and PLU Campus GmbH, where she primarily oversees the areas of strategy, marketing, and sales. As a member of the supervisory board at IF Blueprint AG, she focuses on corporate culture and organization.

As a coach, Christine supports clients in the realm of "Efficient Communication," helping improve mutual understanding and better relationships through the application of Max Lüscher's 4-Color Model. Her expertise also extends to topics such as setting priorities and boundaries through the power of saying "no," stress management, and improvisation in organizational studies using techniques from the renowned Lee Strasberg Institute in NYC.

Privately, Christine resides in Munich. She has a passion for sports, travel, the sea, and sunshine. In her role as a lecturer on regional knowledge and infotainment, she regularly travels on TUI Cruise's "Mein Schiff" and AIDA cruise ships. She spends her vacations with her children in her second home, Spain's Costa del Sol.

Born in Zurich and completing her Abitur (secondary school diploma) in Baden-Württemberg, Christine pursued her education in Munich before venturing out into the wide world. She worked as a junior assistant purser on the Island Princess, traveling nearly all around the globe. Following that, she spent almost three years in Caracas, Venezuela, as a guest relations manager for Starwood Hotels. Eventually, she returned to Munich and, after three years as an executive assistant at Arthur D. Little, took the leap into self-employment. The rest, as they say, is history recorded in the PLU company's story.
