When Grace Smith resolved to quit smoking in 2011, she began with the most common approaches: nicotine gum, the patch, going cold turkey (is there a vegan equivalent to that phrase?).

When a single hypnotherapy session led her to quit that same day, she turned from a skeptic into an avid promoter.

She shifted her career from the high-stress world of New York sales, got certified, and made it her mission to share the power of hypnosis with the world - in her words, "to make hypnosis mainstream."
