Bachelor of Science in Mathematics

Mr. John Pullen

I have spent most of my life in San Antonio, TX, although I’ve lived in a few other places as well, and I am also a 2013 Roosevelt/DATA graduate. Afterwards, I attended the University of Texas at Austin and graduated in the Fall of 2017 with a Bachelor of Science in Mathematics and a 7-12 Math teaching certification. I came back to DATA as a teacher January 2018 and I’ve had the pleasure of working with many of the teachers that taught me when I was a student, which has been a surreal, yet enjoyable, experience. Outside of teaching I enjoy staying active through weight lifting and other forms of exercise, learning new skills such as Piano and Spanish (Duolingo), and trying new recipes to cook. I have been here for 2.5 years and I am very excited to continue to work with DATA students. I’m looking forward to a great year!
