Sig Muller

Sig Muller is a motivational speaker, author, and coach dedicated to helping people unlock their full potential and “Be the World’s Best” version of themselves. A former Division I swimmer at Northwestern University, state champion, and All-American, Sig knows the resilience and heart it takes to push past limits.

In 2024, he survived a sudden cardiac arrest with less than a one percent chance of recovery. That second chance became his mission: to inspire others to live with gratitude, faith, and purpose.

Sig has decades of leadership experience in healthcare, retail, consumer packaged goods, and financial services at great companies including General Mills, Mayo Clinic, Accenture, Ben & Jerry's and UnitedHealth Group. He blends unique corporate insight with raw storytelling to help others rise after setbacks, embrace gratitude, and cultivate lasting excellence.

He enjoys time with his sons, Ashton and Sigareeno, and adventures that connect him with family, faith, and nature.

Dying to Be the World’s Best is his debut book.
