Meet Our Doctors





Our provider staff consists of 3 physicians that specialize in providing pediatric care for children from infancy through early adulthood.  We strive to foster a caring partnership with families, working with them to promote the best possible health for their children.  Our goal is to provide a MEDICAL HOME to our patients, where families can expect compassionate and comprehensive care within our office, convenient access to quality after hour’s advice, and professional coordination of care between our providers and community specialists and services.


We primarily utilize T.C. Thompson Children’s Hospital for extended care. We also see newborns at Erlanger Medical Center, Erlanger East on Gunbarrel, and Parkridge East.
