For over a decade, we've focused on the production of high-quality foods for our local community.

Cornerstone Organics believes in the importance of real, nourishing food.  For us, building a local food system and taking the chemicals out of farming requires cooperation between farmers and customers.

We believe in growing wholesome chemical-free food and getting it on as many table in the community as possible. 

We want everyone in our community to enjoy what is grown right here in the Seaway Valley and help our customers feel confident that what they are eating is the healthiest and tastiest they can find
