My goal is to ease the suffering and stress of patients and families by providing exceptional care through expert medical imaging and communication.



As a pediatric radiologist, my goal is to ease the suffering and stress of patients and families by providing exceptional care through expert medical imaging and communication. I was inspired to pursue my career by the pediatric radiologists and other pediatric subspecialists that I worked with during medical school and residency in Birmingham, Alabama.

Diagnostic radiologists put a great deal of work into making sure our imaging studies provide as much clarity as possible for patients, their families and the referring clinical physicians. This precision includes tailoring the exam specifically for the patient and the concerns of the pediatrician.

I am also passionate about the education of future and current healthcare providers. In 2011, I received the first annual Faculty Educational Achievement Award from among all junior faculty of Cincinnati Children's Hospital Medical Center. In five of the last ten years, I’ve been awarded the Corning Benton Outstanding Educator Award from graduating classes of pediatric radiology fellows.

In research, I have collaborated with numerous clinical subspecialty physicians to improve imaging, diagnosis and treatment of various disorders of the pediatric musculoskeletal system, including many types of vascular tumors and malformations.

In my free time, I enjoy hiking, running and playing with my family — including our dogs, Lola and Max.
