As co-chair of ACOG District II's Safe Motherhood Initiative, Dr. D’Alton has played a pivotal role in the effort to reduce maternal mortality and morbidity in New York State and in the national conversation about how to improve maternal health.

Honored with a Lifetime Achievement Award in 2006 by the Society for Maternal Fetal Medicine, she has served as its president and has held key positions in several professional organizations, including the American Gynecological and Obstetrical Society (AGOS) and the American College of Obstetricians and Gynecologists (ACOG).
