Culinary Roots

William Nelms, affectionately known as "Mr. Fun Guy," brings a wealth of experience to the culinary world. As a seasoned chef, Nelms honed his skills in Philadelphia, crafting pastries for the world-renowned Le Bec Fin Restaurant. His culinary journey also took him to the charming kitchens of Martha’s Vineyard and the vibrant dining scenes of Fort Myers Beach.

Nelms’ passion for mushrooms began when his brother married into a family that owned a mushroom company. They invited him to sell mushrooms in Sarasota, sparking a newfound curiosity and appreciation for fungi. Through dedicated research and hands-on experience, Nelms quickly became an expert, fascinated by their unique flavors, nutritional value, and medicinal properties.
