Gregory C. Martin, MD
Fellowship Program Director

Division Chief of Neonatology, Bill & Cathy Hudson Endowed Chair for Neonatology

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.

Navin S. Bhopal, MD

Navin Bhopal, MD, sees the field of medicine as a crossroad between science and the humanities. "Physicians have to be jack-of-all-trades: scientist, caregiver, social worker, counselor, manager," says Dr. Bhopal, a neonatology specialist at Phoenix Children's. "Having a baby is full of joy and wonder, but it is also a time of uncertainty and anxiety for parents even when the baby is born healthy and full term. Having a baby with medical needs is an extremely difficult time. The task of navigating a sick baby and their family through this process is not only challenging, but also rewarding. "When it comes to providing care for newborns with complex medical needs, Dr. Bhopal believes the best approach combines logic, empathy and compassion. While he is clear about his opinions and recommendations to help guide families in making difficult decisions, he strives to understand and incorporate their values into a personalized treatment plan. For Dr. Bhopal, there's no greater gift than seeing his tiny patients prosper. "It is so rewarding to see a previously small or sick baby grow and thrive," he says. "To see the joy on parents' faces when they take their baby home is like nothing else. Working in a multidisciplinary team to make miracles happen and have a positive impact on the lives of children and their families is what draws me to this specialty. "A dedicated yoga and meditation practitioner, Dr. Bhopal enjoys spending his free time with his wife, infant daughter and their dog. 


Valerie M. Blanco, MD

Amy L. Brown, MD

As a neonatologist, Amy L. Brown, MD, considers it a privilege to provide her tiny, fragile patients an opportunity at life. She believes strong relationships with families built on compassion and empathy can "help families through possibly one of the scariest times in their lives."

Her grandmother's battle - and win - over breast cancer inspired Dr. Brown to become a doctor. "My family was so thankful for the care her medical team provided and the additional years we were able to spend with her," Dr. Brown says.

Babies' resiliency and will to get better drew her to neonatology. "I love helping these little survivors embark on their life," Dr. Brown says.

Warm, friendly staff and the opportunity to impact patients through multiple NICU locations made Phoenix Children's an easy choice for her.

When Dr. Brown isn't working, she loves spending time with her husband, two daughters and two dogs. She also enjoys staying fit with spin classes, yoga and running.

Pamela S. Griffiths, MD

For Pamela S. Griffiths, MD, one of the joys of practicing neonatology is being able to send newborns home after overcoming complicated medical conditions in the neonatal intensive care unit (NICU). "I enjoy playing a role in improving the outcomes of medically fragile infants with complex conditions," says Dr. Griffiths. "Caring for those who are the most vulnerable is especially rewarding. I enjoy seeing a critically ill infant overcome their condition and sharing in the family's happiness when their baby can go home with them. “After receiving her medical degree from West Virginia University (WVU), Dr. Griffiths completed a residency in general pediatrics and a fellowship in neonatal-perinatal medicine at WVU.
