The Pregnancy and Postpartum Partnership of Colorado (P3) was formed in 2002 to bring together agencies, programs and community providers in the state of Colorado to improve perinatal outcomes for women and their babies. P3 is a collaborative group of stakeholders dedicated to addressing the issue of postpartum depression in Colorado. Members bring diverse perspectives and experiences and have built valuable partnerships to improve the mental health of pregnant and postpartum women. Membership is open to anyone interested in advancing the mission.
