MRs. O'Brien

The poet Robert Frost once said, "I am not a teacher, but an awakener," and awakening students to the world around them through reading novels, analyzing poetry and reenacting Shakespeare plays is what Mrs. O'Brien aims to do.

She is also an avid tea drinker and EdTech Nerd.

Dr. Ketcher

6th - 8th History

Daniel Ketcher has been teaching World History, Civics, and U.S. History for eight years at GSOTA. It is the only school where he has taught, and he loves the close-knit community atmosphere. He is very passionate about the subjects he teaches, as well as helping every student reach their highest potential. What he likes most about teaching, is when students ask questions or give comments that are very insightful, and that he hadn't thought about before. He also loves helping students progress from their first encounter with a subject or period, to deep levels of mastery and understanding. He earned his B.A. in International Relations, European Studies, and German. He then completed his M.A. in Philosophical Studies, and finally a Juris Doctorate in Law. He enjoys exercise, music, reading, and cooking in his free time.
