Our Newborn Pediatric Hospitalist Team is on-call 24/7 for those situations that require special diagnosis and treatment.

It’s rare for a non-metro hospital to offer a dedicated pediatric hospitalist team. While most newborns are healthy, our in-hospital pediatric team is on-call 24/7 for those situations that require special diagnosis and treatment. With our newborn pediatric team, most cases can be addressed locally to avoid transfer to a neonatal ICU.

Our hospitalists team is led by board certified pediatric physicians, Dr. Michael Hallenbeck and Dr. Mark Addison. These physicians are supported by two highly experienced neonatal Certified Registered Nurse Practitioners, Shannon Cornelius and Nicole Lamkin. From delivery until your new arrival is ready to go home, you get the expertise and convenience offered by these specially-trained medical professionals.

An additional benefit of the Marshall Medical team is our family-oriented approach. Baby exams are conducted in patient rooms to enhance education and consultation with the mothers. Also, a close network with colleagues at other hospitals benefits moms and babies, along with the Marshall Medical approach of coordinating follow-up steps with area pediatricians to ensure continuity of care.

When it’s time to start making your baby’s delivery plans, Marshall Medical adds peace of mind to this special time for baby and mom. Whether your OB will deliver at Marshall North or South, you will appreciate the added convenience of our pediatric hospitalist team.
