HCA HealthONE Rocky Mountain Children’s

At HCA HealthONE Rocky Mountain Children's, pediatric surgery isn't just what we do - it's where we lead.

Led by William E. Ladd Medal recipient Dr. Steven Rothenberg, our team pioneered many of the minimally invasive techniques now used around the world. This week, he was able to share a hands-on view with our Community Advisory Council. We built the world's first MIS operating suite designed specifically for children and we're advancing care with a pediatric surgical robot-the first of its kind in use in the U.S.

We also lead the world in performing the most:
✅ Laparoscopic Nissen fundoplications in infants and children
✅ Neonatal minimally invasive surgeries
✅ Thoracic lung resections in infants and children

These innovations mean smaller incisions, less pain and faster recovery for our patients.

And a special thank‑you to our Community Advisory Council for their support!

Greta was born, weighing only two pounds, 13 ounces and she survived a one-in-a-million diagnosis thanks to the neonatal intensive care team (NICU) team at HCA HealthONE Rocky Mountain Children’s: https://bit.ly/4oav2n1

This Prematurity Awareness Month, we’re celebrating our tiniest patients and the incredible caregivers at HCA HealthONE who support them and their families. As a proud partner of March of Dimes, HCA Healthcare is committed to improving maternal and neonatal outcomes through clinical data, pioneering research and compassionate care.

Each year, more than 200,000 babies are born in hospitals across our larger HCA Healthcare network – and some arrive earlier than expected. According to March of Dimes, about 1 in 10 babies in the U.S. are born prematurely. This means they enter the world before 37 weeks of pregnancy.

We headed to HCA HealthONE Rose, but the medical team didn’t find a definitive reason for the baby’s distress. My OB/GYN also had a gut feeling about the situation and soon, the team decided I would deliver the baby via C-section.
