Lisa Joy Rosen

1948 - 2025 Lisa Joy Rosen of Los Angeles, California, passed away on December 9, 2025, after a long and courageous battle with cancer. She was 77 years old.
Born in 1948 in Boston, Massachusetts to Shirley and Carl Rosen, Lisa attended the Dana Hall School in Wellesley, Massachusetts, and went on to graduate from Stanford University. Following her graduation, Lisa dedicated herself to teaching at Montessori schools throughout the Bay Area.
In the late 1970s, Lisa moved to New York City to join Puritan Fashions, the company cofounded by her grandfather, Arthur and father, Carl and later led by her brother, Andrew Rosen. As a member of Puritan's marketing team, she consulted for iconic brands including Calvin Klein, Diane von Furstenberg and Marithe & Francoise Girbaud. Lisa had a keen sense of fashion; she was a brilliant merchant and developed many innovative virtual merchandising concepts. In the mid-1980s, Lisa returned to California and continued her work in fashion. Beginning in the early 2000s, she began consulting for the brands Theory and rag & bone, both cofounded by her brother Andrew. Andrew placed enormous faith in Lisa's intuition, point of view and understanding of what women needed. Lisa was the epitome of style, always a step ahead of trends and always dressed impeccably for any occasion. Shopping was one of her favorite pastimes; she was known for her sharp eye and beloved at all the major department stores.
From an early age, Lisa was a standout equestrian and champion competitor. She enjoyed an illustrious show career on the A circuit, placing in the prestigious ASPCA Maclay National Championship finals at Madison Square Garden and winning numerous championships up and down the East Coast. Her love for horses extended beyond the show ring into the thoroughbred racing business, where she was deeply involved in her family's Star Crown Stables. She traveled extensively to racetracks, horse sales, and breeding facilities.
Lisa was a dedicated friend and family member, known for her sense of humor, quirky comments and singular perspective. She was a loving and devoted aunt to her nieces and nephews, with whom she shared an especially close bond. She loved spending time with her nephew, Austin at his music studio and she was a fixture at her cousin David's house, entertaining his kids and grandkids. A lifelong animal lover, Lisa went everywhere with her beloved Newfoundland dog, Luigi.
She is survived by her sisters, Michele Rosen Powers of Middleburg, Virginia and Genevieve Labean Page of Rancho Santa Fe, California; her brothers, Douglas Rosen of Los Angeles, California, and Andrew Rosen of Miami, Florida; her cousin, David Rosen of Venice, California; her nieces, Ashley Rosen and Rosie Powers, and her nephew, Austin Rosen.
