Marcy Grossman, Ambassador-in-Chief/Co-Founder, Supernova Sisterhood Retreats

From criminal psychologist to Canada’s Ambassador to the United Arab Emirates, Marcy wrote the book on radical reinvention. 
Yet her most profound transformation didn’t happen in a war room or a boardroom; it happened in midlife. Following a successful 32-year career in public service, Marcy stepped away from her diplomatic identity to redefine purpose and success on her own terms.
Today, she inspires other women to do the same. At Supernova, she brings her signature framework—Be Your Best Ambassador—to help women navigate the most powerful chapter of their lives.

Who is the heroine of your life’s journey? For Marcy it is Esther from the Old Testament. An unexpected heroine who risked everything to speak out and change the fate of a nation.
