She grew up in Saik'uz (Stoney Creek) village, raised by her mother and her stepfather Johnny Paul.
The Elders' Society built the Potlatch House and the associated campground as economic development initiatives.
She eventually served on the Aboriginal Advisory Committee to the Commanding Officer of RCMP "E" Division, a province-wide body, of which she was a founding member.
In 1997 she was made a Member of the Order of Canada with the following citation: A well-loved and respected elder of the Carrier Nation of the Stoney Creek Reserve in British Columbia, she has dedicated her life to helping others.
She is the strong force and influence behind the success of many positive initiatives and was one of the originators of the Friendship House, a community centre for Native and non-Native people.
She survived many hardships to emerge as a respected elder, counsellor, midwife, educator and conciliator between the Aboriginal and non-Aboriginal communities.
