THe greatest teacher ever! He really cared about his students and helped them as much as possible. He is unforgetable
good teacher but his ideas were the only right ideas. He thinks people cannot change
Possibly the worst teacher I've had in my life. He wants nothing more than mediocrity, and cannot handle students who are actually interested and capable.
We miss you so much Mr. O...you were such an awesome teacher..thank you
We miss him so much ...great teacher and awesome attendance officer!!!
Mr. O'Neill is one of the best social studies teachers i have ever had. I had him my sophomore year and he is an unforgettable person.
