Margit is from Pasadena and attended local schools except for a few years in England, Norway and Spain. She graduated from CSULA with a BA in Art with an Art History emphasis. Margit began working at local florists in the 1970s and was hired as a floral designer for Towle Silver after college. She also free-lanced for premiere Beverly Hills designer, Arthur Simon. With Arthur, Margit was involved with creating arrangements for movie premieres, hotel grand openings, celebrity weddings and award shows.
Margit opened her first store in 1984 in Monrovia. Realizing she immediately needed more space, she and her husband, Ali, bought a commercial corner on Foothill Blvd. in Arcadia where Margit Holakoui Florist is still located. Margit and Ali with daughter Aleah also own Robert's Wholesale Florist, providing fresh flowers and supplies to the public.
Margit is a member of the San Marino League, which provides scholarships for Fine Art majors at Art Center College of Design and supports the Japanese Gardens at Huntington Library, Art Collections & Botanical Gardens. She is also a clock-watcher in the National Charity League San Marino Chapter.
