The list of people she learned from is mostly a who's who of frauds:
"Wallace Black Elk (Lakota); Ed McGaa (Eagle Man - Lakota); Buck Ghosthorse (Lakota); Gloria Two Feathers (Lakota); Brant Secunda,a Huichol shaman; Linda Ross, a profound Navaho medicine woman; Johnson Denison, esteemed Navaho medicine man; David Singing Bear (Cherokee); Rowanna (head of the Hopi medicine society for women); Uqualla (Havasupai ceremonial leader); Michael Harner (an anthropologist who studied shamanism with the Salish tribe in Washington); Sun Bear (Crow)"
We have threads on most of them:
WBE (not his actual name, and no relation to the well known Black Elk)
McGaa, a lawyer posing as a healer
Mattern/Ghosthorse, the white imposter and former KKK member
Secunda, who is white
Quintana/DSB ,who played a part in the mass deaths in Sedona
Uqualla, who is more of a showman
Harner, the disgraced EX anthropologist disavowed by his profession.
What's interesting is her getting Laduke/Sun Bear's tribe wrong. He was an ex actor, Ojibwe posing as teaching Lakota ways to white hippies. He's also been dead a quarter century. It makes me suspect she's just pulling names off the net.
Johnson Dennison is an obvious big exception. He's a well known traditionalist, trying to get western medicine to integrate Navajo healing into its practices. I'd guess she may have encountered him during her time as a social worker.
There are two possibles for Linda Ross. One is much like Dennison. Another claims to be a psychic surgeon.

Having an Indonesian wife, I know they don't call their healers "shamans." They call it simply traditional medicine or healers. Most Indonesians are Muslim, most Balinese are Hindus. There are older traditions like Aluk To Dolo and Kejawen. Pretty obvious she chose the shame on name for marketing purposes.
Moved to Frauds, though there's still much that can be researched on her.
