Peggy Carnahan has devoted her career to the teaching of science and the teaching of science teachers. A former science teacher at Jay High School and secondary science supervisor for the District, Carnahan served Northside for more than 20 years. Her contributions to the District continue today, through her work at Our Lady of the Lake University, where, as the director of the Center for Science and Mathematics Education, she helps science teachers obtain tuition-free master's degrees. Carnahan has received numerous teaching awards and is recognized across the state and the nation as an innovative leader of science education. In her 44-year career Peggy Carnahan has taught high school biology, directed the science program for NISD, directed one of the five national implementation sites for Project 2061 of the American Association for the Advancement of Science (AAAS), directed the San Antonio Rural Systemic Initiative funded by NSF, founded the Center for Science and Mathematics Education at OLLU, through grants funded master’s degrees for 500 science teachers, and established the state’s largest, most active, and most respected science teacher network. Educator and Industry Advisory Boards established by Carnahan keep her informed of both school and community needs and in touch with potential opportunities to further the growth of science teachers. She was the first female to be named a Fellow of the Texas Academy of Science. Those who work and learn with Peggy Carnahan consider themselves inescapably “Pegged for life.”
