NEW YORK CITY – When Hamptons Magazine announced its event in celebration of tennis superstars Venus and Serena Williams, Avi Oster Media was chosen to organize the event. The soiree, which represents a branching out for the boutique media company, went off without a hitch – and many say attracted more attention than even the sister athletes could have expected.

Avi Oster Media, headed by entrepreneur and real estate developer Avi Oster, has a history of making neo-chic faery tale evenings. Oster, who founded the company after building his name developing specialty residential and shopping properties in and around New York, is a master of bringing Manhattan’s elite together for unforgettable evenings. Thus he was a natural choice, insiders say, for the magazine’s magical night.

Hamptons Magazine, a lifestyle periodical with a strong female audience, chose to highlight the superstar duo to celebrate their recent successes on the court. Serena and Venus, who have a longstanding professional rivalry but exhibit strong sisterly affection off the court, have both held the No. 1 title in women’s tennis. Venus has 43 career titles and Serena has 39. The two were the center of a chic whirlwind of supporters at the event.

The venue for the event, RdV Lounge, is a hidden playground for the young elite of Manhattan. Located in the trendy meatpacking district, it sports a mixed aesthetic of lush classical furnishings and edgy, cool music hand-picked for the event. While Avi Oster Media has in the past specialized in fashion and philanthropic events, this new splash into celebrity spotlights may be the beginning of something great.
