Prof. Emily Constancio
Professor Constancio attended Tarleton State University for both her bachelor’s and baster’s degrees in mathematics, with an emphasis in Education. She has also obtained her secondary certification in mathematics, allowing her to work at area ISDs for various number of years.
While the study of mathematics is very important to her, Professor Constancio’s greatest love is for her family. In her very rare spare time, she enjoys gardening and sewing.
Mrs. Jessica Brown
Mrs. Brown teaches beginning-level math courses. Her degree is in Mathematics with Secondary Certification from Tarleton State University. She has taught at the secondary and post-secondary levels. She loves helping students to see math in an uncomplicated way. Eliminating fear from the equation is her main tactic in teaching math.
When Mrs. Brown isn’t teaching, she helps her husband in their ministry. She loves her role as a “preacher’s wife” and feels blessed to be part of a church family. The Browns live on a small yet growing farm and enjoy spending time with their two dogs.
