Since Dr. Oz's first Oprah Show
appearance in 2004, Oprah says he's been both a teacher and a healer for millions of viewers. Over the course of 55 shows, he's inspired smokers to kick their habit
, dieters to drink green smoothies
and children to eat their veggies
…to name a few!
Though he'll still join Oprah in Chicago from time to time, he's packing up his medical bag and heading to New York City to host his own show, The Dr. Oz Show
