Ms. Sarah Selke

Sarah has devoted the past 20 years in meeting the demands of her two gifted children. She home-schooled her children in mathematics since elementary school to better serve their needs. Working on challenging math problems with her children and their friends alongside with their math coaches were the happiest times in her life. After her children left home for college (one sophomore in CS at CMU and the other Ph.D. student in Math at Stanford), she becomes a private math coach training gifted K-12 students for math competitions.
Sarah holds a Ph.D. from Electrical and Computer Engineering at Purdue University. She was trained in Applied Mathematics in Tsinghua University in Beijing. She competed in many math competitions in her younger days and she was the first-prize winner in high school in Hubei Province in 1984. Sarah is one of the best lecturers in the Statistics Department at Purdue University. Her students say "she created an extremely friendly, motivating, intellectually stimulating and open classroom atmosphere while providing great quality instruction".
One of the best compliments from her student is: "She is absolutely amazing.It feels like I'm learning from my mom and I feel like we are all her children." Rest assured that Sarah will teach your children as if they are her own.

Mrs. Carena White, M.Ed, M.A

Has been in education for 19 years. Born and raised in a small rural community in Rock Point, Arizona. Rock Point is a Navajo community on the Navajo Indian Reservation. She attended Fort Lewis College (Colorado) where she majored in Secondary Education. She became a Mathematics teacher at Rock Point High School in 1997. She later taught at two other high schools, Many Farms High School (Many Farms, AZ) and Red Valley/ Cove High School (Red Valley, AZ) on the Navajo Indian Reservation.
She holds graduate degrees: MEd in Curriculum and Instruction from Arizona State University, Tempe, AZ and a MA in Educational Leadership from the University of Northern Colorado in Greeley, Colorado. She had the opportunity to hold several administrative jobs as an Exceptional Education Coordinator (K-12), Dean of Instruction (High School), K-12 Principal but she continues to find her greatest passion to teach high school Mathematics and help Navajo children to be enthused about learning math and to encourage them to be active in the Math Circle.
She is grateful to be back in the classroom today at Newcomb High School, Newcomb, NM!
