Our Story
Two River Gourmet Mushrooms is a small-scale mushroom farm situated on a 25 acre parcel of farmland preserve in historic Millstone, N.J. We grow high quality USDA Organic mushrooms for the passionate, knowledgeable, and creative chef or home cook who desires only the finest ingredients.
Founded by KC Sullivan as a passion-project in 2014, Two River has grown exponentially since founding and boasts a dynamic team with specialized mycology knowledge.
We are certified Organic and to date, we are the only USDA Organic Mushroom farm in the state of New Jersey that grows many of the specialty strains of mushrooms that we offer! Those varieties include Shiitake, Oyster, Maitake, Pioppino, Lion’s Mane, Chestnut, and many others.
We currently provide our Gourmet Organic Mushrooms to 40 of New Jersey's finest restaurants such as Anjelica’s, Gabriella’s, Blu Grotto, Il Nido, Red Horse etc. We also supply 16 retail locations such as Sickles, Delicious Orchards, Nature’s Corner, Foodtown, Deans, as well as several local CSAs.


Our Vision
The vision of the dual enterprise between Two River Mushroom and Mighty Dare Farm is to create a unique setting where we not only produce organic gourmet mushrooms but also complement each other in a biodynamic, regenerative relationship.
We envision a location where people can visit and immerse themselves in a wide range of experiences from farm-to-table gatherings that draw on the organic mushrooms and heirloom vegetables, fruits, and herbs from our gardens; informative workshops; event space opportunities; CSA memberships; retail shopping; and so much more.
Our unique setting and relationship allows us to work closely with our community and customers as we continue to find special ways of delivering the freshest, best tasting, local, and organic produce in this area. At the heart of our business is ensuring that everything we do is centered around our sustainability principles to protect our planet and future.

Five patient steps
Organic hardwood blocks, living culture, weeks of quiet incubation — then fresh air, high humidity, and a hand-picked harvest at peak. No shortcuts, because you can taste shortcuts.
