Over the course of her 20+ years at Koerner Kronenfeld Partners, a boutique consulting and media production firm, Nathalie has worked with ambassadors, generals, boxers, authors, concert pianists, playwrights, Broadway performers and high-level executives at Fortune 500 companies. Personal favorites include working on the books: You: The Owner’s Manual by Dr. Mehmet Oz and Dr. Michael Roizen, If Not Now When by Medal of Honor recipient Col.
