Regina Quattrocchi, chief executive officer of Bailey House, the first supportive housing agency in the United States for people living with HIV/AIDS, died on Dec. 14.

A 1971 graduate of The Mary Louis Academy, Jamaica Estates, under her tenure, Bailey House grew from a small agency providing housing for people with HIV/AIDS into an $18 million organization that provides housing, care coordination, mental health and substance use treatment to New Yorkers living with the virus and other chronic illnesses.

She also was a former president of the National AIDS Housing Coalition and served the community in various roles, including as a member of the New York State Ending the Epidemic Task Force; as a member of the Harlem Hospital Community Advisory Board; and a board member of iHealth NYS.

Her contributions as an advocate and leader were widely recognized over the years. Her most recent awards of distinction were given this year in conjunction with World AIDS Day by the New York City health department and the Brooklyn-based group Bridging Access to Care.

She is survived by her two children.
