Sperber joined The Four Seasons Hotel of Beverly Hills, the first Four Seasons in the Los Angeles area. An instrumental member of the pre-opening team, Sperber developed successful corporate and leisure accounts, surpassed departmental sales, booked over 3000 room nights per month, and established and managed successful client incentive programs to Hong Kong and London. Sperber was also responsible for bringing the United States Presidential party to the hotel. This continued a lengthy relationship with the United States Government and the Secret Service that has enabled Sperber to book royalty, political and diplomatic clients in each hotel she has represented.

Upon her return to the Century Plaza Hotel and Towers, as Director of Corporate Sales, Sperber doubled the booking pace by using her client base of members of the entertainment community and senior corporate executives from all over the United States and Europe.

Sperber joined Merv Griffin's Beverly Hilton Hotel as Director of Corporate Sales, and once again, achieved positive results. She exceeded budgeted room nights and average rates.

Always dynamic, Sperber formed her own company to maximize her experience, relationships and expertise. The Sperber Hotel Group services exclusive and distinguished hotels throughout the United States, Europe and Mexico. The Company makes personal calls on corporate and leisure accounts, manages several direct mail programs and customizes innovative promotional programs.
