About lymebasics.org

Who we are, our mission, and our focus


We are an all-volunteer 501(C)(3) non-profit organization, dedicated to improving the lives of people suffering from Lyme and other tick-borne diseases, as well as their caregivers. Since our inception in 2003, we have been providing reliable information, patient assistance, and education in support of the Lyme Disease community.

lymebasics.org was formerly known as the Lyme Disease Association of Southeastern Pennsylvania (LDASEPA). We plan to provide additional support to the Lyme Disease community by expanding our reach beyond Southeastern Pennsylvania. We’ve changed our name to support this expanded scope.
