About the Provider

Dr. Lannon guides women facing unexpected and sometimes significant challenges during high risk pregnancies toward making decisions that result in the healthiest possible outcomes for mother and child. Although she is passionate about helping families through all high risk pregnancies, she has a particular interest in managing anticipated and unanticipated preterm birth. Dr. Lannon has published articles on the timing of very preterm cesarean deliveries, timing of antenatal steroids, infectious causes of preterm labor, the risk of adverse obstetric outcomes among Native American women and the use of antihypertensive medication in pregnancy.

Dr. Lannon’s professional experience includes being on the teaching faculty at the University of Washington. In 2015 she was honored with a teaching award by the Council on Resident Education in Obstetrics and Gynecology division of the American Congress of Obstetricians and Gynecologists. Dr. Lannon and her husband have two small children. She enjoys spending time with family, traveling and outdoor recreation, such as hiking, bicycling and running with her dog.
