Professional History


Principal, Isabelle C. Greene and Associates, Landscape Architects, Santa Barbara, CA, 1964- . Her professional statement stated: "Isabelle has led the practice in the rediscovery of a garden aesthetic that boldly steps beyond the historical templates of European gardens, embracing the unique visual qualities of the spaces and the plants themselves: compositions that deftly reinterpret the landscape, inventing anew rather than repeating past practices. Like the Abstract Expressionists, Greene’s work moves us beyond recognized images to the essence of the garden experience.Deeply committed to sustainable practices, her landscapes age well and flow with the land and climate naturally, conserving water, energy and materials. While she is noted for her distinctive treatments, her eye for detail and proportion acknowledges her legacy as granddaughter of Henry Mather Greene, of Greene & Greene Architects, pioneers of the early Craftsman movement in Southern California. Her passion for enduring results, like theirs, is apparent in her landscapes. Ms. Greene’s commitment to construction detail is reflected in the highly crafted quality of the gardens’ elements. She displays uncompromising rigor in the design and execution of her projects, developing a personal standard of excellence that fellow practitioners would do well to emulate."
