My Great Strides Story

July 18, 2024 was one of the happiest days of my life as we welcomed our third child, Josephine.
Less than two challenging weeks later, after countless sleepless nights and growing concern as Josie struggled to gain weight, our world shifted. She was diagnosed with cystic fibrosis. The days that followed were a whirlwind of emotions: sadness, fear, and deep anxiety about what her future might hold.
Through the incredible support of her care team and the reassurance of how far medical research has come—much of it driven by the Cystic Fibrosis Foundation—we slowly found hope and confidence. We learned how to support Josie, advocate for her, and help her persevere.
Today, she is a thriving, beautiful, strong, and confident toddler; Our daily reminder of resilience and hope.
While tremendous progress has been made, there is still no cure for cystic fibrosis. I’m walking to help change that reality.
CF is a genetic, life-shortening disease that devastates the lungs, pancreas, and other vital organs. CF makes it difficult to breathe and fight life-threatening infections, often leading to extensive lung damage and respiratory failure.
Every person born with cystic fibrosis is on a unique journey and experiences this challenging disease differently. While progress has been made, a long road lies ahead for far too many people fighting this terrible disease. We need a cure so that everyone with CF has a better chance to live a long, healthy life.
