We are a national network of experts in reproductive and children’s health issues related to environmental exposures.
Together, we make up the Pediatric Environmental Health Specialty Units (PEHSU) and work collaboratively to improve health systems to make communities safer for children and families. We provide community education and outreach, training for health professionals, and guidance and referrals.
Families & communities
We work with parents; schools; community groups; federal, state, and local government agencies; and others to address reproductive and children’s environmental health issues.
- Information and resources on environmental hazards
- Practical advice on helping children recover from an exposure or cope during and after environmental disasters
- Connections to specialists who can work with your health professional
Health Professionals

- Consultative guidance to HCPs
- Assistance identifying and interpreting appropriate diagnostic tests
- Professional training in practice, through CEUs, events, and peer-reviewed articles
- Resources on a variety of environmental hazards or topics
