She was the first women to serve on the Medical Center of Delaware's board between 1993 and 1997, and was a trustee of the Christiana Care Health System for nearly 30 years.

Before the death of her husband, she donated $2.5 million in support of the construction of the Roxana Cannon Arsht Surgicenter.

She described herself as "gutsy, independent and not afraid to challenge the status quo" and was considered one of Delaware's most influential women in the past half-century.
