Señora Dietel has been teaching at Glen Crest since August 2002. She originally taught physical education classes for grades six, seven, and eight. In 2005, she began teaching two sections of Spanish, in addition to teaching four PE classes (seventh and eighth grade only). Beginning in the fall of 2007, Sra. Dietel started teaching Spanish classes the entire day, and no PE classes.

She is enjoying the Spanish curriculum and sharing her knowledge and experiences with all of her students. In addition to taking Spanish classes throughout high school and college, Sra. Dietel lived in Cholula, Puebla, Mexico for the spring semester of 2001 when she was in college. During this semester, she was able to travel extensively and had the amazing opportunity of living with Mexican roommates and taking normal classes on the campus of the Universidad de las Américas (UDLA). In the summer of 2019, Sra. Dietel traveled with the College of DuPage to live, study, and travel for a month in Spain. The majority of this time was spent in Madrid, with side trips to Granada, Córdoba, Valencia, Salamanca, and Toledo.
