Marni was named a Top 100 Who's Who by Women in E-Commerce Magazine and was a cover and featured article in Grey Matters Magazine.

She is also a sought-after guest on radio shows on business and personal empowerment.

She  is the author of The Iceberg Principles, which outlines the philosophies that make Marni's strategies so transformational and empowering. She was also a contributing writer to the book, Insider Strategies of Industry Leading Consultants.


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

Marni tells the harrowing story of how she was molested, raped and forcibly addicted to heroin. She became a prostitute, a criminal, was homeless for a time and finally, ended up in prison.

She emerged fiercely determined to create a better life for herself and, in short order, built a multimillion-dollar business. She lived a fabulous life, yet a sense of fulfillment somehow remained elusive. She had not yet realized that she had merely traded steel handcuffs for golden handcuffs and was still trapped in a prison of sorts.

What happened next drove home the point with ferocity. She was diagnosed with a deadly disease and only given a year to live.

Surprisingly, this became her greatest gift. With seemingly nothing left to lose, Marni discovered the phenomenal power behind radical authenticity. It helped her, not only to survive but, thrive.
