Lynnette was born in California, where her family moved for her father's job. Her mother is Northern Arapaho of Wyoming's Wind River Reservation, and her father is Hunkpapa Lakota Standing Rock Sioux. She attended Pasadena City College and Mt. San Antonio College in Walnut, CA.
Lynnette has spent her life working on outreach, advocacy, and community improvement, including homeless outreach in L.A.'s Skid Row, United Way Arizona's Project Homeless Connect, a Native American outreach foodbox program with deliveries to tribal nations across the country, and served as chair of Arizona Commission for Indian Affairs, where she worked with 26 different tribes, coordinating their issues with governor's office. From 2006-2010, Lynnette participated in the To Set the Captives Free Women's Mission Program, a mentorship program for CCA, a federal prison in Florence, Arizona, where she helped women inmates to prepare to successful transition back into society.
In 2013 Lynnette became a tribal liaison for government and non-profit entities, training and advising on AMBER alerts and child sex trafficking in Native American communities. She also founded Not Our Native Daughters, a non-profit dedicated to educating and bringing awareness to the Missing and Murdered Indigenous Women and Girls crisis. In 2014 she began lobbying on child trafficking bills, which had previously not been a national priority. One of the most frustrating issues of that time was an "ignorance defense"--child traffickers could claim they didn't know a child was underage to avoid being charged.
Lynnette moved home to Wyoming in 2017, during the Sundance Ceremony; Wind River tribal elders wanted to start a non-profit to address issues on the reservation, and invited her to help. She also served with the Wind River Early Childhood Intervention Program, helping kids progress with speech and development, and continued consulting and training on MMIW.
After the Standing Rock protest sparked nationwide "critical infrastructure bills," Lynnette began lobbying the Wyoming legislature to protect our rights to freedom of speech and peaceful protest. In 2018, she was the Wind River Reservation/Fremont County Field Organizer for the Wyoming Democratic Party, working primarily on Native voting rights and access and the election of Wyoming Rep. Andi Clifford (D-Fremont).
Lynnette submitted testimony to a 2016 congressional briefing on tribal suicide rates. She contributed to a 2017 report on human trafficking in Indian Country submitted to the UN during a special session on global child sex trafficking. She also successfully testified to protect the Tribal Heritage Protection Act, in place since 1953 and the Grizzly Bear Protection Act--an issue Rep. Liz Cheney (R-WY) later said was "ruining our western way of life".
Lynnette currently serves as director of the Wind River/Department of Interior Land Buyback Program for Tribal Nations , where she manages staff of 7 who work on the distribution of the settlement of $1.9B for the mismanagement of tribal land, making land offerings to tribal land owners. She is a tribal liaison for the Wyoming Outdoors Council and a Red Desert Tribal Advocate for Citizens for the Red Desert Coalition. Lynnette is the mother of three biracial children; her eldest son is a sophomore at Central Wyoming College, and her younger son and daughter attend public schools in Fremont County.
