Thoughtful Catering Inspired by the Land

GB Culinary brings together high-level culinary training, Colorado-grown ingredients, and a deeply personal approach to hospitality.

Founded by chef Grant Buchanan and his wife Kaylinn, GB Culinary grew from a vision of creating food that feels connected to place, season, and gathering. After training at Le Cordon Bleu in Paris in both Culinary Arts and Pastry Arts, Grant built his career in acclaimed kitchens throughout the Vail Valley and cooked for internationally recognized guests and events. Eventually, the couple traded the traditional restaurant path for something more grounded and intentional: a working farm in the foothills outside Longmont.

Today, that farm shapes everything they do. GB Culinary grows produce, raises livestock, and designs menus around what is fresh, seasonal, and available close to home. Their approach combines refined culinary technique with an easy, welcoming style that feels elevated without ever feeling formal.

From intimate dinner parties and rehearsal dinners to weddings, farm suppers, nonprofit events, and large celebrations across Colorado, each experience is customized to reflect the people and setting behind it. Menus are ingredient-driven, thoughtfully curated, and designed to create memorable moments around the table.

Serving Boulder, Denver, Aspen, Telluride, and destinations throughout Colorado, GB Culinary has become known for events that feel personal, beautifully executed, and effortlessly warm. Whether hosting a backyard gathering or a mountain wedding weekend, their team brings creativity, professionalism, and genuine hospitality to every detail.
