Neonatologist Gregory C. Martin, MD, recognizes what caring for newborns with medical challenges can mean for a child and their family. "Effective care can impact a child for a lifetime," says Dr. Martin. "I love the idea of giving the most fragile infants a chance at life."

Providing specialty care for babies born with complex or high-risk conditions runs in Dr. Martin's family. His mother was a neonatal intensive care unit (NICU) nurse. His uncle is also a neonatologist. "Visiting my uncle's NICU with my mother as a child inspired me to be a doctor," says Dr. Martin.

Phoenix Children's Hospital's mission to provide hope, healing and the best healthcare for children and their families inspires his care every day. He carries out that mission using a team approach that leverages the expertise of specialists. Together, they create a plan for evidence-based care.

Dr. Martin understands that helping families is an important part of the care he provides, too. "I truly enjoy the moments spent with each family, supporting them during their time of need," says Dr. Martin.

When he's not caring for patients, Dr. Martin relaxes by spending time with his wife, Robin, and children Aydin and Hannah. He also enjoys staying active with tennis, swimming and golf.

When Marc Ellsworth, MD, was in medical school, his wife's experiences as a nurse in the neonatal intensive care unit (NICU) inspired his interest in specializing in neonatology. As a neonatologist at Phoenix Children's, he puts the needs of his tiny patients and their families first. "There is nothing better than watching a family take home a healthy baby who at one time was critically ill," says Dr. Ellsworth. His two older brothers, both pediatricians, influenced Dr. Ellsworth's decision to pursue a career in medicine. He is grateful to be at Phoenix Children's, where specialists from a wide range of disciplines work together on the most complex cases. "The quality of subspecialty expertise and care coordination of Phoenix Children's is something I value. It helps me take care of the sickest infants," he says. In his free time, Dr. Ellsworth enjoys spending time with his wife and three children.
