Dr. Gerdes’ clinical and research interests include neurodevelopmental outcome of infants with preterm birth and congenital abnormalities. Her focus also includes universal early childhood developmental and behavioral screening, including children of immigrant and refugee families, expanding the focus of screening to ensure that early identification leads to services, and also encouraging a preschool experience for all children to support school readiness.
Her work with preventive interventions and services for young children at risk includes services for children with mothers who are depressed and also children whose challenging behaviors placed them at risk for expulsion from childcare. Her approach to research has an emphasis of building community partnerships and bridging research to practice and policy change.

Patient Experience Ratings
About the Patient Experience Rating System
The Patient Experience Rating is an average of all responses to the care provider related questions shown above from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question.
Responses are measured on a scale of 1 to 5 with 5 being the best score.
We are committed to true transparency. However, to ensure the comments are fair and correctly attributed, we review each one before posting to the website. We exclude entire comments that disclose patient's protected health information, are off-topic, or include other confidential or inappropriate content. Comments will appear on provider bios only if providers have a minimum number of comments.
Comments are shared internally for education purposes to ensure that we are doing our very best for the patients and families for whom we are privileged to care.
The comments are submitted by patients and families and reflect their views and opinions. The comments are not endorsed by and do not reflect the views of Children’s Hospital of Philadelphia.
