Reiner’s mission is to mobilize and develop leaders to create a more sustainable and positive future for all. As an executive coach, he works with leaders and changemakers in a wide range of organizations, from start-ups and multinational companies to non-profits and local communities - all who aspire to create transformational change. Whether he’s working with corporate executives, entrepreneurs, intrapreneurs, or indigenous tribal leaders, Reiner’s clients appreciate his international business and cross-cultural leadership experience. Before becoming an executive coach, Reiner had a 30-plus year career in technology, started and developed software businesses, and led leadership development. At Hewlett-Packard, his home for 20-plus years, he launched new software product businesses and helped grow HP Software into a multi-billion dollar organization. While at HP, Reiner discovered his passion and talent in leadership development where he trained leaders in how to scale from leading one’s self, to leading others, to leading an entire organization. Reiner grew up in the western part of a divided Germany during the Cold War. Reiner’s heartache over his country’s role in the Holocaust and World War II awoke in him a lifelong desire to address the challenges that threaten future generations. Reiner is fluent in English and German, and his clients benefit from his global education, deep expertise in sustainability, and his many years as a community organizer. He holds an MBA in Sustainable Business from Pinchot University (now Presidio University) and a Master’s Degree in Computer Science from the University of Paderborn (Germany).
