The Rock CF Foundation

Founded and led by Emily Schaller, the Rock CF Foundation is dedicated to increasing the quality of life for people with cystic fibrosis. With the help of a core group of volunteers, the Foundation utilizes the arts, entertainment, fashion and fitness to support a variety of programs, scholarships and research initiatives for those with CF.  What began as one woman on a mission to educate her peers has evolved over the course of 16 years into a multi-faceted organization inspiring people living with CF to lead more healthy lifestyles and bringing awareness to an illness that often goes unseen, ensuring it doesn't get forgotten. 

 

The Rock CF Foundation is a community, thousands strong, changing the face of what living with cystic fibrosis looks like and giving those living with CF the tools to not only survive, but thrive. Learn more here: https://letsrockcf.org/
