Master Your Money. Transform Your Life.
What's your relationship with money?
Supportive? Stressful? Nonexistent?

If you're like most people, it's complicated, and often unhealthy. After more than 30 years guiding clients as a senior portfolio manager, Mary Hagerman saw firsthand how money can distort lives, fuel anxiety, and sabotage dreams. But she also discovered a better way.

As a 3rd Dan Black Belt in Karate, Mary brings a unique perspective to financial wellness. She believes true wealth isn't just about numbers, it's about discipline, clarity, and emotional strength. Just like martial arts, financial mastery is a journey. And it starts with understanding yourself.

From White Belt to Black Belt, Your Financial Transformation Starts Here

In The Black Belt Investor, Mary blends the wisdom of martial arts with decades of financial expertise to guide you through the stages of financial fitness. You'll learn how to:

  • Break free from destructive money habits
  • Silence the noise of fear, shame, greed, and jealousy
  • Stop fighting with your partner about spending
  • Make confident decisions about investing and big purchases
  • Build a long-term plan rooted in self-awareness and purpose

This isn't just a book, it's a blueprint for "wealthiness", Mary's term for the deep sense of peace and power that comes from a healthy relationship with money.

"I found the book fascinating. It aligns with many of my values, but I still learned about several key things that I will try to put into practice or improve, such as meditation, self-discipline, continuous development and improvement, and philanthropy.

Thank you for this book and all the benefits it will bring to me."
