I know a woman who is verified Haudenosaunee, but whose practices are in question by many in my community. She runs a "healing centre" that is funded by the government, but money/donations have disappeared with no explanation as to where it went. She also heads up a drum group for which she requires new women to burn their existing drum before they can join her (certainly no tradition I have ever heard of). She has also openly admitted physically abusing one of her husbands - biting him. Overall, not someone I would want running a native healing centre.
Because she is actually Haudenosaunee though, I don't know if more info would be welcome here, or if this forum is just for cultural frauds?
