The historic preservation organization, SOS, Save Our Sites has been co-founded by David S. Traub to advocate for the preservation of sites and structures within the city of Philadelphia.

These sites include historic ones, though they may not always be certified or in historic districts. The modern, the vernacular and those properties not fitting into any particular category, are the focus of Save Our Sites as well. Therefore, Save Our Site's mission goes beyond historic preservation in the narrow sense, with the intention of preserving Philadelphia as a highly livable, traditional city.

Save Our Sites, in addition to its focus on preservation, advocates for new development that is appropriate to each site and that is compatible with its surroundings.
