About Us

socius – Latin, meaning: partner, comrade, associate, ally.

Socius Construction is a partnership of longtime friends Jon Hartman and David Salfrank, who grew up together in Lancaster County, PA. Each had been working separately in the construction and concrete trades beginning in 1998 before coming together to found Socius Construction early in 2004.

Since that time Socius has dramatically expanded the scope of its work to include restaurant renovations for both popular chains and individual restaurateurs. While we continue to work and thrive mainly in Lancaster and Southeast Pennsylvania, Socius’ work also reaches to neighboring New Jersey, Maryland, and New York as well as several Northeastern states.
