medicine professor Phyllis Gardner at Stanford, Gardner responded, "I don't think your idea is going to work", explaining it was impossible to do what Holmes was claiming could be done. Several other expert medical professors told Holmes the same thing. However, Holmes did not relent, and she succeeded in getting her advisor and dean at the School of Engineering, Channing Robertson, to back her idea. In 2003, Holmes renamed the company Theranos (a portmanteau of "therapy" and "diagnosis"). Robertson became the company's first board member and introduced Holmes to venture capitalists. Holmes was an admirer of Apple founder Steve Jobs, and deliberately copied his style, frequently dressing in a black turtleneck sweater, as Jobs did. Holmes says her mother dressed her in black turtlenecks when she was young and that she had worn the turtlenecks beginning around the age of eight, but an employee says she suggested copying Jobs's famous Issey Miyake turtleneck look in 2007. During most of her public appearances, she spoke in a deep baritone voice, although a former Theranos colleague later claimed he heard her speak in a voice stereotypical of a woman her age to welcome him when he was hired. Gardner of Stanford also denies that Holmes has a naturally deep voice. Her family, however, has maintained that her deep voice is authentic. Funding and expansion By December 2004, Holmes had raised $6 million to fund the firm. By the end of 2010, Theranos had more than $92 million in venture capital. In July 2011, Holmes was introduced to former secretary of state George Shultz. After a two-hour meeting, he joined the Theranos board of directors. Holmes was recognized for forming "the most illustrious board in U.S. corporate history" over the next three years. Holmes operated Theranos in "stealth mode" without press releases or a company website until September 2013, when the company announced a partnership with Walgreens to launch in-store blood sample collection centers. She was interviewed for Medscape by its editor-in-chief, Eric Topol, who praised her for "this phenomenal rebooting of laboratory medicine". Media attention increased in 2014, when Holmes appeared on the covers of Fortune, Forbes, T: The New York Times Style Magazine, and Inc. Forbes recognized Holmes as the world's youngest self-made female billionaire and ranked her #110 on the Forbes 400 in 2014. Theranos was valued at $9 billion and had raised more than $400 million in venture capital.
