The site has continued to grow at an unprecedented rate and is now in six different languages with more than 8 million registered users across the globe.  The Barbie Girls™ device, an innovative music (MP3) player and next generation fashion doll that unlocks premium content on BarbieGirls.com, was named to the prestigious Toy Wishes “Hot Dozen” list and was one of the must-have girl tech toys of 2007.

O’Neill joined Mattel in 2004, as a product manager on the company’s core Barbie® business, overseeing development of Barbie® dolls, fashions, and accessories.  In 2006, O’Neill assumed responsibility for the Barbie Tech division. Leading Barbie into the digital age, O’Neill has secured partnerships with key players in the digital space, including Apple, through the launch of Barbie® Chat Divas™.  

 Prior to joining Mattel, O’Neill served four years as Account Manager for a marketing communications agency, developing campaigns for brands such as Razor USA, Nature Made vitamins, the Got Milk? campaign, Hitachi, and Children’s’ Hospital Los Angeles.

She received her B.S. degree in communication studies from the University of California, Los Angeles and holds a M.B.A. degree from UCLA’s Anderson School of Management.
