Seane Corn

Age: 41

Occupation: Yoga instructor and community activist

Why she matters: Has channeled the goodwill of the yoga community into funding charitable causes.

CORN wants to save the world, and she's off to a good start. In the last decade, she has evolved from simply a driven yoga instructor into a committed community organizer and charity worker.

She's been practicing yoga for more than 20 years, and teaching it since 1994. Her classes, which blend vigorous vinyasa yoga with visualization and prayer, have gained a devout following -- and the media have taken notice. She's been featured in Glamour, Fitness, Self and Allure magazines and has been tapped by Nike to appear in national commercials and print campaigns.
