Mr. O'Donnell is a great teacher. I had him over 25 years ago for Geometry and I can still remember many things that I learned in his class. He is a true professional.
Mr. O'Donnell was amazing. He always went out of his way to make sure that I understood the lesson. He also has such a great sense of humor.
Mr O'Donnell is a good teacher, although somtimes he can act up and be stubborn. I think its about time he retird. Hes kind of old, you know?
