After graduating from the Brown School, Charles became the executive director of the first tribally charter child welfare agency in the nation, Lakota Oyate Wakanyeja Owicakiyapi Inc. (LOWO), the Oglala Sioux Tribe's Chartered Child Welfare Organization. 

“Much of my work can be attributed to what I learned at the Brown School. I administer the day-to-day operations of LOWO’s programs. LOWO assumed the Child Protection Services from the state of South Dakota in February of 2008. Since then I have helped build capacity and develop culturally relevant programs to serve children, youth, and families on the Pine Ridge Reservation, and LOWO currently has agreements with the state of South Dakota, Bureau of Indian Affairs, and Casey Family Programs, which provide us our primary funding.”

“The Brown School provided the degree I was seeking and a scholarship, and I was taught by some of the best social work professors in the nation. Through the Kathryn M. Buder Center for American Indian Studies, I networked with some of the most influential leaders in Indian Country. The knowledge I gained at the Brown School has been invaluable.”
