My Why
Changing Lives One Cookie, One Book, and One Moment at a Time
I believe we are not entitled to time.
Life has taught me that lesson more than once.
After developing severe life-threatening food allergies as an adult, I experienced multiple episodes of anaphylaxis and was resuscitated twice. The most serious occurred on June 5, 1999, when I was six months pregnant with my son Cameron. After unknowingly eating a chocolate chip cookie containing walnuts, I went into near-fatal anaphylactic shock. Surviving that experience forever changed my perspective on life, gratitude, purpose, and the understanding that tomorrow is never guaranteed.
Then, in 2004, my father suffered a life-altering stroke. During his recovery, I witnessed the power of resilience, compassion, and community in an entirely different way. While participating in speech therapy, he shared a remarkable series of inspirational words that would later become the foundation for Percolate: Let Your Best Self Filter Through. What began as his journey of recovery ultimately helped inspire a body of work dedicated to helping others navigate change, discover their best selves, and live with greater purpose, gratitude, and peace.
That cookie changed everything.
It taught me that tomorrow is never guaranteed. It reinforced the importance of gratitude, preparedness, resilience, advocacy, and living with intention. It became the foundation for much of the work I do today.
My husband, Peter, and our four sons are my greatest blessings and my greatest teachers. They have shaped my understanding of what truly matters and continually remind me that meaningful and comprehensive success is about far more than accomplishments. It is about family, relationships, service, purpose, gratitude, and the impact we have on others.
Early in my college years, I also made a conscious decision to stop drinking alcohol. After a frightening experience that could have ended very differently, I chose a path of intentional living and have remained alcohol- and substance-free ever since. I deeply respect and support those who are choosing lives of healing, growth, and transformation.
These experiences inspired me to create Best Ever You, found Food Allergy Zone, co-found The Percolate Peace Project, write books about change, success, gratitude, and peace, and dedicate my life to helping others become their best selves.
Chocolate chip cookies remain a powerful symbol throughout my work. They represent inclusion, kindness, gratitude, resilience, and the simple truth that small actions can change lives. Since 1998, my family and I have baked and donated tens of thousands of nut-free chocolate chip cookies to children, families, schools, charities, and communities across the United States. What began as a simple act of kindness grew into a mission of helping people feel safe, included, valued, and celebrated.
I often say that success is a lot like baking the perfect chocolate chip cookie. It requires the right ingredients, patience, consistency, care, and a willingness to share what you've created with others. True success is built on a foundation of world-class excellence, gratitude, and service.
At the heart of everything I do is a simple philosophy:
When our lives touch, my goal is for both of our lives to be better as a result.
Because we are not entitled to time, I believe it is essential to align our hearts, truths, and energy to create meaningful and comprehensive success in all areas of our lives and to bring peace into each moment—for ourselves, the people around us, and the world as a whole.
Whether through a book, a keynote, a podcast conversation, a coaching session, a random act of kindness, a Peace Promise, or a homemade chocolate chip cookie, my hope is always the same: to leave people with more hope, more peace, more possibility, and a greater belief in themselves than they had before we met.
Because when you grow, the world grows with you.
