Our specialists

Our caregiver team offers best-practice care that only a major center like ours can provide. Herma Heart Institute doctors are consistently ranked among The Best Doctors in America and offer some of the best outcomes in the nation. What’s more, we’re the only pediatric heart care program in Wisconsin where all caregivers are full-time fetal, neonatal and pediatric experts.

Children’s Hospital of Wisconsin is committed to providing you the information you need to make informed decisions about your heart specialist. As part of that commitment, we post our patient satisfaction ratings within our provider profiles.
