After losing Ryan to suicide in the fall of 2014, Suzie felt the need to turn their tragedy into something positive by helping other teens and young adults from spiraling into depression and suicidal behavior when times get tough. In a short space of time, what started as a peer-led support group for teens at the high school Ryan went to, has now become a non-profit whose programs touch all corners of the Loudoun community. 


Today Suzie juggles her professional life with advocating and working in her free time for the Foundation. She is an active speaker in the community and an advocate for mental health and youth suicide awareness and prevention through the empowerment of youth.
