Our Mission:

Operation Medical is an organization of volunteers made up of trained medical professionals and other individuals committed to promoting and providing high quality medical care and education to communities that do not have adequate access to medical care.

Our Vision:

Operation Medical’s vision is to become recognized as a leading organization in Central Pennsylvania for supporting a strong and varied network of healthcare providers and other individuals dedicated to providing medical care and supplies to individuals for whom such care is problematic.

How We Are Different:

We do not have boundaries to the types of medical services we are willing to provide or places we will travel. Our emphasis is on the medical needs of the community, with the safety of our patients and our volunteers being our #1 priority. Our safety and quality protocols ensure our patients receive the best care possible. All trips are carefully coordinated with local hosts and their medical community in order to optimize the success of our visit and make certain our volunteers have a positive experience. We audit results and provide training for all of our partners.
