Students, administrators, fellow teachers and the surrounding community are dealing with the shock from the sudden passing of North Central Middle School (NCMS) teacher Helen Charlene Mathis on April 29. Mathis, known by her middle name and only 43 when she died, taught math at NCMS. She began working at the school in 2005. “Ten years ago, I had the good fortune of hiring Charlene Mathis to the faculty at North Central Middle School. (She) possessed all the attributes of the perfect teacher -- loving, caring, patient and knowledgeable,” NCMS Principal Burch Richardson said.
