Read Dr. Morris Kummer's Bio

Dr. Morris Kummer has been drawn to babies and young children from an early age. As a grade-schooler, she loved gazing at the newborns in the hospital where her mother worked as a nurse. Now that she is all grown up, her most beloved work as a pediatrician is caring for newborns and supporting caregivers as they navigate the first amazing (and exhausting!) months of new parenthood.

She grew up in the Twin Cities and earned a BA in Biology at Carleton College in 2002. The following year, she studied in Bergen, Norway as a U.S. Fulbright Fellow, where she learned about the Norwegian model of midwifery and obstetric care. She earned her Medical Degree from The Warren Alpert Medical School of Brown University in 2010 and completed a Pediatric Residency at the University of Massachusetts in Worcester in 2013.

During residency, she augmented her book learning by becoming a parent—an experience that has profoundly shaped how she supports other families as a pediatrician. After the birth of her son, Dr. Morris Kummer experienced unexpected difficulties with breastfeeding, which ignited her passion for supporting her patients’ lactation goals and ultimately led to her becoming an IBCLC and Breastfeeding Medicine specialist. Every family’s infant feeding journey is unique, and Dr. Morris Kummer’s approach is to listen deeply and empower new parents with the knowledge, skills and mindset for an enjoyable
infant feeding experience, however it might evolve. She will support you with evidence-based lactation care, including medical diagnostic evaluation and management as needed for complex lactation concerns.

In addition to 11 years in practice as a primary care pediatrician and newborn hospitalist, she has authored several research studies on breastfeeding and human milk. Most recently, she worked for 5 years as an Academic Pediatrician at Mayo Clinic, where she taught pediatric residents and medical students and led Quality Improvement initiatives in addition to her clinical care. Dr. Morris Kummer is currently pursuing certifications through Postpartum Support International (PMH-C) and the Boston
Children’s Brazelton Institute (Newborn Behavioral Observation [NBO]). She serves as the Assistant Medical Director of the Minnesota Milk Bank for Babies and as Co-Chapter Breastfeeding Coordinator to the American Academy of Pediatrics’ Section on Breastfeeding for Minnesota. She is also a member of the Minnesota Breastfeeding Coalition.

Outside of work, she loves spending time with her family (hubby, 2 boys, a dog, and a cat), traveling, expanding her vegetable and perennial gardens, and taking long walks with friends. She is exploring sourdough baking, mindful meditation practice, and yoga (and is loving all three!). Dr. Morris Kummer is so excited to be able to provide family-centered, expert newborn care in the comfort of your home, and she looks forward to collaborating with you to build your postpartum village.
