Earthstone Ovens was founded in 1987 by Maurice Sabbagh Yotnegparian, a car mechanic who relocated from France to California in the 1950s. An avid cook, Yotnegparian found time to explore culinary pleasures while pursuing his craft restoring luxury cars in the Los Angeles area. He became friends with several French chefs in LA and built a pizza oven at his home. Eventually he began importing and selling ovens from France. The initial success of this venture led him to design and build his own ovens. Today Earthstone produces a large selection of residential and commercial ovens and accessories.

Because much of their business is commercial, all components must be food grade. All ovens are manufactured in California and are UL and ULC listed backed with a five year limited warranty. Earthstone is still owned and operated by the Yotnegparian family.
