Dr. Carmen Fletcher Schreane

Finding Inspiration in Every Turn
Dr. Carmen Fletcher, U.S. veteran, Juris Doctor, and visionary founder of KNOWNO®, is on a mission to stop addiction before it starts. With a background in international law and behavioral prevention, Dr. Fletcher created KNOWNO®, the world’s first anti-addiction card game and media brand that empowers children to say NO to peer pressure through books, games, and animation.
Her brand partners perfectly with Listerine’s values of health, prevention, and bold confidence — creating safe minds and bright futures, one family at a time.
My Supportive Family — The Original KNOWNO Masters.
KNOWNO® is more than a brand — it’s a mission 28 years in the making, built on faith, sacrifice, and the unshakable love of my family. Through every twist, trial, and turning point, my family has been my foundation — and they are the true origin of KNOWNO’s strength.
My sisters, daughters, sons, and husband are the Original KNOWNO Masters. Long before these characters lived on cards or danced across animated screens, they lived in my home, my heart, and in our shared values. They were the first to hear the stories, test the games, give honest feedback, and believe — even when resources were low and the world didn’t understand the vision.
KNOWNO was born in 1997, the night I had a dream that changed everything: in it, my then 12-year-old son was addicted to drugs, following the same painful path as his father. I woke up shaken — but clear. I couldn’t just hope he’d make the right choices. I had to do something to prevent it.
But I knew a slogan wasn’t enough. A lecture once or twice a year wouldn’t reach him — not when he was distracted, closed off, or caught in peer pressure. I needed a tool — a way to teach him to say “NO” over and over again, before the moment of temptation ever arrived.
That’s when the seed for KNOWNO was planted — a fun, relatable, and powerful game that could prepare kids long before the streets tried to.
After graduating from Thomas M. Cooley Law School in 2004, I made a bold decision: instead of chasing a traditional law career, I followed my destiny — to bring KNOWNO to the public and help save lives.
To this day, my law degree remains sealed in its original container, tucked away in my closet. When asked why it’s not framed and hanging proudly, I simply say: “Because I haven’t found an office worthy of it yet.”
Not until KNOWNO has a home built on purpose — not prestige. I’ve sacrificed job offers, financial stability, and countless comforts — but never the mission.
My family carried it with me, every step of the way. Together, we created KNOWNO to give children the strength to say NO before they’re ever pressured.
KNOWNO® was not born in a boardroom. It was born in a dream, nurtured by a mother’s love, and built in our living room with tears, faith, and fearless hope. This isn’t just a company. This is our legacy.
