Billie Duncan-Smith is the founder of CTWHH. In 1995, it was discovered that her husband, Stephen, had an undiagnosed white matter disease. Billie relentlessly searched the Internet where her efforts finally culminated in her husband's diagnosis with CADASIL in 1997. She has been involved as an advocate for CADASIL since that time and has made contacts throughout the world bringing people and information together. Billie set up a website for CADASIL in 1997, which is known worldwide and along with the logo “Together We Have Hope.” Prior to her husband’s illness, Billie taught Youth Sunday School classes and was treasurer for a local area food bank where she organized area food drives. She received an Associate's Degree in Accounting and Office Skills from Hartford Mid-Cheshire College in Northwich, England as well as an Associate's Degree in Computer Information Management in 2005 from Ashworth University in Norcross, Georgia.

Billie taught a beginning computer course for adults in 2001. Outside of her job, she volunteers and is dedicated to CADASIL. She is a caregiver to her husband who has CADASIL. Her interests are computers, crafts and photography. Billie and Stephen have two daughters, a granddaughter, and a grandson. Billie can be personally contacted via e-mail at
