Others will work with outsiders. Some people who are not Native American believe that working with a traditional healer has helped them. Most healers work in their local tribal communities. A few participate in public conferences. If you are not a tribal member, it is very difficult to know if someone is really a traditional healer.
Many people use the techniques of traditional healing.
However, there is a big difference between traditional healing and using traditional techniques. Participating in a sweat lodge might help almost anyone. However, the experience could be very different depending on who runs the sweat lodge. Also, a sweat lodge will mean more to someone who grew up in a tribe that traditionally uses them. Some techniques might have no meaning unless you grew up using them.
