We invite you to browse our website to learn about Fetal Alcohol Spectrum Disorders (FASD), the leading known cause of intellectual disabilities in the United States. FASD is caused when a woman drinks alcohol during pregnancy and is 100% preventable. Share in our vision of all children being born free of any prenatal alcohol exposure.
