Modica Market, which opened March 17, 1989 by Charles Modica Sr. and his wife, Sarah, began with a simple deal-sealing handshake between Modica and Seaside founder Robert Davis, and has since flourished into one of the most recognizable businesses along Highway 30A. As the market celebrates three decades in business, the next generation of Modicas — Charles Modica Jr. and Carmel Modica — run the store together.
