Who better to teach us how to unmask what matters in our own lives than the Broadway star who played Christine Daae in The Phantom of the Opera? Sandra Joseph, the longest running Christine in the longest running Broadway play, has just released her book on Phantom's 30th birthday: Unmasking What Matters: 10 Life Lessons from 10 Years on Broadway. Her life unrolled like a fairytale: from too shy to sing in an elementary school performance to starring in a Broadway show and marrying the lead (a man who played the Phantom) - how romantic is that? But, when she finally stepped off the stage, she was confronted by the death of her beloved father and her own medical crisis, a brainstem tumor. These challenges caused her to 'unmask what matters' for herself and realize that she wanted to use her voice to inspire audiences in a new way. She's now on a mission to empower other people's voices through her work as an author, speaker and thought leader.
