"I love to help mothers and babies breastfeed successfully and enjoy this unique relationship!"

Dr. Knox worked with mothers and babies in the Newborn Intensive Care Unit, for many years, and on both UW coasts, before finding her true calling: helping mothers and babies with breastfeeding problems. She still works in the NICU and also sees outpatient babies for the assessment and treatment of suspected tongue tie.
