Example Strategic Investments

Children’s National Medical Center

In 2018, The Trust invested $1 million to create the Children’s National Community Mental Health Core (CMHC). Nationally and in Washington, DC, 1 in 5 children has a diagnosable mental disorder and 1 in 10 has a serious mental health problem that is severe enough to impair how they function at home, school, or in the community. Mental health is optimally addressed across the physical health care, social support, and education delivery systems using a whole-child, family-centered approach.

Proton Therapy Collaboration

In 2013, the Stewart Trust pledged $1 million for a proposed joint pediatric radiation oncology and dedicated pediatric proton beam facility for Children’s National Medical Center, Sibley Memorial Hospital, and Johns Hopkins University. Proton therapy is more precise and less toxic than conventional radiation therapy and has been shown to be beneficial for specific types of patients, including children with cancer and adults with tumors near vital organs.
