Mr. Oescher is the best mathematics teacher I ever had in high school or college. He was so good that I was able to become a math teacher myself based off the knowledge and thought processes he fostered in me. Teaches you how to think not mimic.
The best math teacher I have ever had!
Mr. Oescher is a great teacher and really cares about his students' educations. He goes above and beyond what is expected of most teachers.
He introduced me to concept-learning rather than process-learning. He's an actual college teacher and helps prepare students for college learning. A little hard, but he's worth it.
The man is a mathematical genius, but more importantly an expert teacher. Clearly and accurately explains concepts and assigns good examples of problems.
