Kim Hardiman

CSU Program Director

Kim Hardiman

I am originally from Pennsylvania and moved to Aiken South Carolina 10 years ago with my husband and 2 daughters. Shortly after our move here I began working at Serenity. I became the nurse manager of the Crisis Stabilization Unit (CSU) in February 2017. I am a certified psychiatric and mental health nurse and have worked as a nurse for over 35 years. I believe it is my calling and I know it is my passion to help others live their lives to the fullest. For Individuals admitted to the CSU, discharge planning starts on admission. When there is a plan there is hope, and when there is hope there is a future. There is nothing more rewarding than to work with our Individuals and to see the smiles return to their faces and to hear hope in their voices. Serenity gives me the opportunity to have and to share that experience.
