A doctor sat across from Mark Dant and told him his young son likely wouldn't live past age 12. In an instant, the future he and his wife imagined disappeared.

What followed wasn't a story about medicine alone. It was a story about grief, fear, hope, persistence, and the ordinary decisions that eventually create extraordinary outcomes.

Mark shares how a police officer with no scientific background learned enough about genetics to help drive a treatment forward, why he believes hope is an action rather than an emotion, and what it means to keep moving when the future you've imagined disappears overnight.
