Founding Partner

Diana Gil-Osorio founded Ellipses Public Relations in 2007 after a 15-year career in public relations, marketing and broadcast media.  She officially incorporated and re-launched the company in partnership with Tami von Isakovics in 2009. Diana is creative, driven, connected and a champ at interpreting where public relations fits in this modern world of social networks, blogs, consumer-driven content and new media.

Over the past three years her clients at Ellipses Public Relations have included the launch of Chef Michael Mina’s Clock Bar at The Westin St. Francis in San Francisco and Rye bar’s San Francisco cocktail catering company, Rye on the Road, as well as overseeing the publicity for Maestro Michael Morgan’s 20^th Anniversary Season at the Oakland East Bay Symphony; Peas of Mind; celebrity chef Ryan Scott; Whisk Group in Washington, DC; and GreenPath®, the environmental stewardship program at Yosemite National Park. She spearheaded publicity and marketing for the Fourth Annual San Francisco Cocktail Week for the Barbary Coast Conservancy of the American Cocktail, and was executive producer of the Fifth Annual San Francisco Cocktail Week in September of 2011.

Prior to founding Ellipses, Diana was Director of Public Relations at The Ritz-Carlton, Half Moon Bay from 2003 to 2007, where she was responsible for the AAA Five Diamond golf, spa and tennis 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.

While at The Ritz-Carlton, Diana 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 across the country.  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 joining the hospitality industry, 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 Silicon Spin, 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 Oakland and is the founder of PR Divas, a Bay Area networking group for professional women in public relations.
