About Us

Experience the Best in Fresh, Organic Mushrooms

At The Oyster Farm at Carter Lake, we are passionate about cultivating high-quality, organic mushrooms right here in Berthoud, Colorado. As a small, family-run farm, we are committed to sustainable growing practices, ensuring that our mushrooms are always fresh, chemical-free, and packed with flavor.

Founded by Eugene Reinersman and Christopher Chawula, former emergency medicine professionals, our farm was born from a love of both cooking and the powerful health benefits of mushrooms. Beyond offering gourmet mushrooms for culinary use, we also explore their functional and medicinal properties, partnering with Vitality Nutrients of Loveland, Colorado, to create organic, water-soluble, and alcohol-free mushroom and natural plant extracts.

Whether you’re a chef looking for premium mushrooms, a home cook eager to try something new, or someone interested in the natural benefits of functional mushrooms, we invite you to discover what makes our farm special.

Join us in bringing the best of mushrooms to your table—fresh, local, and organically grown.
