Joyce IoanesAttorney, Mental Health Advocate

Joyce Ioanes, 62, an attorney and mental health advocate for the state of Rhode Island, died Feb. 20 of acute myeloid leukemia at Miriam Hospital in Providence, R.I. She was a resident of Jamestown, R.I.

Ms. Ioanes was born in the District and grew up in Falls Church. She was a member of the first graduating class of Bishop Denis J. O'Connell High School in 1961 and played basketball and was a cheerleader. She received a bachelor's degree in 1965 from Dunbarton College of the Holy Cross and moved to Paris shortly afterward. She returned to Washington and taught French at Woodrow Wilson High School for a semester and also worked for the American Association for the Advancement of Science.

She moved to Rhode Island in 1968 and began a career as a social worker. After receiving a master's degree in psychiatric social work from Simmons College in 1971, she decided that many attorneys working on behalf of the mentally ill didn't understand their legal needs, so she enrolled in law school. She commuted to Boston by train to attend classes at night, receiving a law degree from Suffolk University in 1983.

She worked in Rhode Island's Office of the Mental Health Advocate for 35 years and was the assistant mental health advocate at the time of her death. A civil libertarian, she worked tirelessly for the rights of the mentally ill.
