The breastfeeding and lactation team at The Children’s Hospital of Philadelphia is comprised of a director, four international board-certified lactation consultants, more than 650 specialty trained breastfeeding resource nurses, and the full support and backing of a Hospital-wide breastfeeding committee.
Together, our team is available to help all new moms with lactation support. Whether your baby can feed at the breast or not, you can ensure your child has essential nutrients found in human milk by pumping and storing your milk.
Members of our lactation team are available for consults around the clock, and often work with moms at their baby’s bedside in one of the Hospital’s intensive care units. Breastfeeding resource nurses are also available at multiple facilities within the CHOP Care Network in Pennsylvania and New Jersey.
This page offers biographical sketches of each of the core members of the breastfeeding and lactation team at CHOP. Our hope is that by getting to know them a little better, you will feel comfortable calling them for help with your breastfeeding questions and concerns.

D’Andrea became IBCLC certified in 1999, and has dedicated herself to helping all women succeed in their breastfeeding goals.
D’Andrea has been a member of CHOP’s lactation team in the Newborn/Infant Intensive Care Unit since 2008. She looks forward to continuing her work supporting and mentoring clinical staff to assist breastfeeding mothers and babies.

After having her own children, Devine viewed becoming an international board-certified lactation consultant as a natural extension to her role as a bedside nurse. She currently works with breastfeeding families throughout the hospital to support their feeding goals, while engaging with hospital staff to promote and educate in all things breastfeeding-related.
