Kathrin is an internationally recognized and accomplished management consultant and coach with a long and impressive track record of leadership and executive success in one of the world’s most ambitious and hard-charging Fortune 500 companies, Robert Half. Born, raised, and educated in Europe, Kathrin’s early interests and passions for languages, philosophy, and the arts stood in sharp contrast to the corporate career she was about to embark on. She received her degree in Socioeconomics from the University of Hamburg and a postgraduate certificate in International Business Administration from Henley Business School in the United Kingdom.
Soon after joining Robert Half, she established herself as a top 5% consultant in the company globally and was first promoted to lead the operations in Northern Germany before taking over responsibility for all of Robert Half’s recruitment operations across Central Europe. Due to her unparalleled success and her fully bilingual language capabilities, she was transferred to global headquarters in the United States, first as a Director for one of their key markets in the San Francisco Bay Area, and then as a Vice President on the east coast, becoming the company’s internal turnaround specialist and leading the transformation of multiple Robert Half offices and practices around the world.
After her successful leadership career, Kathrin decided to start her own consulting and coaching practice to bring her leadership and experience to companies both inside and outside the professional services industry. During this time, she also received her ICF coaching certification and became a senior consultant for the Arbinger Institute, where she led global culture change initiatives.
Before co-founding Withiii with Jim, Kathrin led Arbinger's international business as Managing Director of the Germany-based international entity and as the company's head of international expansion, while she continued to serve as a group facilitator, change consultant, and public speaker on mindset change for large international organizations.
When not working or training for her next triathlon, Kathrin loves visiting museums, attending classical concerts, playing the piano, and riding her road bike for miles on end. And she golfs. If she has to.
Andrea is a seasoned business leader, executive coach, speaker, and entrepreneur with a passion for helping individuals and organizations reach their highest potential. Aside from her role at Withiii, Andrea also serves as the Chief Learning Officer and co-founder of ed-tech company Oji Life Lab, where she has designed and launched innovative and transformative learning programs that blend psychological research with practical application, helping individuals and organizations thrive in the modern workplace. Her solutions continue to support employees at organizations such as Amazon, Johnson & Johnson, and California State Parks.
Before co-founding Oji, Andrea led a $30 million revenue region for a publicly traded company. Her success as a leader and her unparalleled drive for leadership excellence and personal growth led her to eventually serve as the company's Senior Director of Global Job Skills Training, where she implemented and facilitated learning programs for leaders and top performers around the globe.
With her passion for inspiring change and helping people thrive, Andrea is a truly gifted speaker and facilitator. She speaks regularly at conferences on leadership development, emotional intelligence, and the future of workplace learning. She has guided hundreds of teams through transformative processes that elevate relationships, performance, and well-being. As a certified coach, speaker, and practitioner, she has empowered thousands of professionals to achieve meaningful growth in both their personal and professional lives.
Andrea believes that “leadership energizes. It doesn’t scold, belittle, or demean. True leaders lift up those around them and help them see what’s possible—in themselves and in the world.” She is a true embodiment of Withiii's mission to overcome divides and bring people together.
Outside of work, you can find Andrea in a bee suit tending to her two hives that produce the most delicious honey you have ever tasted, or teaching a class at a yoga studio in the San Francisco East Bay.
