Speaking with People magazine in her first interview since reporting to Federal Prison Camp Bryan in Bryan, Texas, Holmes maintained her innocence and said she was “not the same person I was back then.”

Holmes, the founder and CEO of blood-testing startup Theranos, is roughly two years into her 11.25-year sentence, which has been reduced to nine years for good behavior.  In her talk with People, she says her best moments in prison are the twice-weekly visits from her children and partner. And she never expected she would actually go to jail, she revealed.

“I always wanted to be a mother,” she told the magazine. “I truly did not think I would ever be convicted or found guilty.”

As part of her prison routine, Holmes wakes up daily at around 5:00 a.m., eats a breakfast of fruit, then does 40 minutes of exercise. At 8:00 a.m. she begins her job, as a reentry clerk at the facility’s education building, earning 31 cents per hour. There, she helps women write résumés and apply for tax credits. She also works as a law clerk and teaches a French class, the magazine says.

Once a week she attends cognitive and behavioral therapy for PTSD overseen by a psychiatrist. And in her spare time, she reads, everything from I Ching to the Harry Potter novels. Twice a day, she calls her family, often waiting an hour or more for a phone to open up.

While she is scheduled to be a prisoner through 2032, Holmes maintains she is unfairly imprisoned.

“I refused to plead guilty to crimes I did not commit,” she said. “Theranos failed. But failure is not fraud.”

As for her post-prison life, Holmes says she plans to return to the world of health care technology and is already working on new inventions.

“There is not a day I have not continued to work on my research and inventions,” she said. “I remain completely committed to my dream of making affordable health care solutions available to everyone.”
