LOUISVILLE - The Door to Door Organics Inc. online grocery store delivery network is expanding into New Jersey, Delaware and Pennsylvania through its wholly owned subsidiary Suburban Organics.

Suburban Organics will be renamed Door to Door Organics Tri-State starting Friday, Feb. 1. Ottsville, Pennsylvania-based Suburban Organics will operate as part of the parent company in the future, rather than independently as it has been for the last two years, said Chad Arnold, president and chief executive of Door to Door.

The operations and name change helps Door to Door leverage its supply chain as it expands, Arnold said. The two companies have been working together since 2010, when Door to Door bought Suburban Organics for undisclosed sum. Door to Door's existing operations are in Colorado, Illinois, Missouri and Michigan.

Customers in New Jersey, Delaware and Pennsylvania will be able to get new products such as local milk, eggs, cheese and grass-fed beef and bison once the change is complete, the company said in a press statement. A new website for the Tri-State area will show offerings of local organic fruits and vegetables, as well as more than 1,000 chef-tested recipes using ingredients sold by Door to Door.

Door to Door Organics has received investments to grow in the past, including $2 million in venture capital in August from Greenmont Capital Partners LLC in Boulder.

Louisville-based Door to Door does not disclose revenue figures, Arnold said.
