Administrative Staff

Nancy Davis 2013Nancy Davis – Head of School
Nancy joined the UMS administrative staff in August, 2009. She first discovered Montessori education in 1986 when her son began attending a small Montessori school. Like many parents, she loved what she saw happening there and decided to pursue her Montessori training. She received her certification in San Diego and has taught children from primary through upper elementary. She served as a Montessori consultant for a public magnet program in North Carolina and, after receiving her state certification, served as principal of the same school. During that time, Nancy also earned her Master’s Degree in School Administration. A move to Illinois led to an administrative position overseeing the operations and educational programs of a network of retreat/conferences centers across the U.S. Nancy, along with her husband and daughter, have now relocated to Tulsa and Nancy says she is delighted to be returning to a Montessori setting as well as to be close to their son, daughter-in-law and granddaughter who have settled in Tulsa.
