Mr. Keith Thurston, Faculty Representative

Mr. Thurston graduated from the Air Force Academy with a degree in Aeronautical Engineering (surprisingly only 5% of his class chose this major) and a Minor in Mathematics.  He worked on the F-16 design team, and then decided to get his MBA from Arizona State University.  He spent 25 years in technical sales with stints at 3M, as well as owning his own sales firm.  One of his life-long dreams was to end his career in teaching, preferably math.  He is indebted to the public school system that gave him such a great start, and feels a personal obligation to return the favor.

He is married (since 1977) with three grown, successful children. 

He finds, as a life-long learner, the environment at TPA both professionally invigorating and challenging.  He is humbled to be entrusted with the education of (this year) 85 students.
