Kourtney Otamendi is the outstanding senior of the year at New Vision High School, Post Fall’s alternative high school. Hers was an unusual upbringing. It was not the idyllic picket fence, family dog, nuclear family picture. She lived with a foster family in Dallesport, Wash., for four years, until her aunt, Regina Lind, received her foster care license and was able to take in Kourtney, 19, and her younger sister, Whitney, 18, during Kourtney’s freshman year. Lind lived in Athol at the time, then moved to Post Falls.
