Diana Gil-Osorio
President and Founder

Diana Gil-Osorio (say dee-ahn-a) brought over 15 years of experience in public relations, marketing and broadcast media to the 2007 launch of her own publicity practice, Ellipses Public Relations. Diana is creative, driven, and a champ at interpreting where public relations fits in this modern world of social networks, blogs, consumer-driven content and new media.
As Director of Public Relations at The Ritz-Carlton, Half Moon Bay (2003–2007), Diana was responsible for the AAA Five Diamond resort’s media relations, promotions, special event creation and production, community relations, as well as all internal and external communication. Her efforts contributed to significant annual increases in top-line revenue and international acclaim by driving annual media impressions from 600 million in 2003 to 1.2 billion in 2005. (Yes, that’s a lot.)
She founded and produced the KKSF Concerts on the Coast series; celebrity chef and author culinary classes with Gourmet magazine and Viking; as well as the annual Gingerbread House Contest and Silent Auction benefiting a local children’s charity. In the fall of 2005 and 2006 she co-founded and produced Inside the Kitchen, a wildly successful food and wine weekend benefiting Meals On Wheels, generating big buzz and drawing people from all over the Bay Area. In recognition for her efforts, in 2005 she won Public Relations Leader of the Year for The Ritz-Carlton Hotel Company’s Western Region and the Visionary Achievement Award for Inside the Kitchen.
Prior to The Ritz-Carlton, Diana worked as a publicist for Encore Communications, a boutique agency based in San Francisco that specializes in the arts and entertainment. She secured and managed all broadcast media for the San Francisco Symphony’s 2003 Black and White Ball, which attracted over 11,000 patrons. Prior to Encore, she served as public relations manager for Business 2.0, a Time Inc. technology-focused business magazine.
Diana’s extensive media experience stems from over three years (1999–2002) as the senior booking manager and guest producer at TechTV, a technology entertainment cable channel based in San Francisco, where she secured guest interviews with over 1,600 well-known celebrities, CEOs, authors, journalists and analysts for the network’s national television shows including The Screen Savers, CyberCrime, GameSpot TV, Working the Web, and Internet Tonight.
Prior to TechTV, Diana was an account associate at Antenna Group Public Relations, where she represented David Bowie’s ISP, Bowie Net, in 1999.
Diana has a B.A. in Communication from Lewis & Clark College in Portland, Ore. She lives in San Francisco and volunteers for the American Heart Association.
