PDI has launched a new lifetime membership level.  Those who join the Landmark Society, contributing $2,500 or more,  will never again receive renewal notices, and will receive invitations to special events and benefits available only to Landmark members.  Please consider renewing at the Landmark level when your membership renewal notice next arrives - you could make it your last notice! 

Through your membership you will be assisting initiatives aimed at preserving Delaware's valuable architectural resources and their surrounding landscapes. Your tax-deductible membership contribution enables PDI to launch innovative programs and broaden the support for preservation activities in the First State.
