In 1933, Sister Parish began her design career in a one-room shop in New York City, and over the years cultivated a style that established her as one of the most important designers worldwide. Her signature use of bright colors and deluxe fabrics produced a feeling of unparalleled grace and luxury that quickly became an American classic. Celebrated in private homes of impressive clients such as the Astors and Engelhards, Jacqueline Kennedy chose Sister Parish to decorate the White House during Kennedy's term, signaling Parish as one of the most sought-after interior designers in the nation.
However, Sister Parish was not to develop her design firm alone. In 1964, Albert Hadley, a native of Tennessee, joined Mrs. Parish and the design firm became Parish Hadley, Inc. With an eye for modern, sleek, tailored elements, Hadley contributed an interesting counterpart to Sister Parish's more traditional designs. The designs are widely recognized for the timeless, elegant style inherent to the Parish-Hadley fashion. Together, Parish and Hadley successfully cultivated a unique manner of decorating which has become synonymous with classic, yet distinctly American, style.
