Speaker and bestselling author, Marni Spencer-Devlin teaches her empowering brand of radical personal and professional Authentic Leadership to corporate professionals.

In her bestselling autobiography, Crawling Into the Light, Marni tells how she was molested, raped and forcibly addicted to heroin. She became a prostitute, a criminal, was homeless for a time and finally, she ended up in prison.

Then she discovered a secret that allowed her to emerge empowered. From this she created a multimillion dollar business with seventy employees and for twenty years Marni lived a phenomenal life. Then came another shock. She was diagnosed with a deadly disease and only given a year to live. But yet again, an even deeper dive into this one secret helped her not only to survive, but thrive.

Today Marni is busy sharing her unique brand of leadership and personal development with worldwide audiences, focusing on executives and corporate audiences. Marni also loves speaking to teens and college students, and women in prison.

Marni offers coaching to very select clients.
