About me

  • Medical Liaison, ChildProtect Program, Lancaster General Health

I grew up in a rural community in Central Pennsylvania then pursued my undergraduate and medical education in New Jersey.  My husband and I completed our residencies in Pittsburgh.  I have lived in Lancaster since 2002 and love the community, the small town vibe, and the access to big cities.  I enjoy partnering with families to educate them about health topics, safety, immunizations, and growth and development.  I love watching children and families grow and change over time.  Outside of the office, I am an avid reader, love to cook, travel and enjoy spending time with my family and numerous pets.  I enjoy tinkering in my garden and pond.  My husband is an emergency medicine physician. We have two adult children, a son and a daughter.

Education and training

  • Medical School: Rutgers-Robert Wood Johnson Medical School
