Leonora Zilkha Williamson - Founder

Job Titles:
  • Founder
Leonora Zilkha Williamson is the Founder of Platinum Rule Advisors (PRA), a consulting firm devoted to human capital strategy and executive coaching for leadership teams, especially of family-owned businesses. Prior to starting PRA, she served in leadership roles at J.P. Morgan, Boston Consulting Group and Estée Lauder. Leonora's "side hustle" is teaching Negotiation and Corporate Social Responsibility to undergraduates as a Lecturer at Vanderbilt University. She also serves on the board of family company Sabre Yachts and has served on dozens of non-profit boards, including a current seat on the board of Learning Matters, an organization working to reduce learning barriers and ensure educational equity for K-12 students with learning differences. A graduate of Princeton University and Harvard Business School, she is a certified coach (PCC) through the International Coach Federation and a member of the Harvard Institute Of Coaching, Forbes Coaches Council, and Marshall Goldsmith's 100 Coaches, an invitation-only group of accomplished coaches who are committed to using their talents to make people and organizations better. She was named Nashville's #1 Executive Coach in 2021 and 2022 by Influence Digest and has been recognized by the Nashville Business Journal as a 2022 Women of Influence award recipient. She has lived in 8 countries, speaks 5 languages, and carries 2 passports. She lives in Nashville with her two daughters and a golden retriever named Scout. She began her career in investment banking and management consulting. In those environments, personal life and professional life were, for the most part, not to be mixed. She found this phenomenon curious - people walked into work each day with their whole stories, and her most productive working relationships were those where she formed personal connection. Her passion for focusing on a whole person was born. Her role as Executive Director, International at M⋅A⋅C Cosmetics (Estée Lauder subsidiary) was the perfect way to put this passion to work. Leonora's team was responsible for delivering a P&L generated in over 60 countries, yet the brand managers in each country reported to their Estée Lauder country head, not their M⋅A⋅C head. This dotted line relationship meant Leonora could manage only with "carrots" and no "sticks." She traveled around the world listening to concerns unique to each market. Which products work well in Asia? How do we ensure our visual branding is appropriate in deeply religious countries? How do we navigate complex regulatory environments that delay launch timing for new products in some of our most prominent countries? These are the types of problems Leonora solved by working through others in cultures not her own. It was a challenging task and she loved every minute of it.
