But some people refuse to adapt to modern technology, preferring a more traditional and respectful (to some people's perceptions) way of marketing services.
Take Francis Mitchell for instance. The Navajo Nation member chooses not to promote his services as a medicine man online. Rather, he relies on word-of-mouth. Mitchell's choice stems from a cultural belief that medicine men should not advertise their services.
"It's not supposed to be a competition," Mitchell told The Farmington Daily Times of his practice. "It's not a way to recruit business, a way to identify yourself."
Mitchell has clients on other continents, but he only uses the telephone to reach them. He does not own a cell phone or have Internet.
"Medicine is an attempt to assist, so modern technology is not part of it."
