Chemistry is a difficult subject, which of course causes his class not to be so easy, but he is a great guy and is always willing to help a student with their work. And he seems to love what he does. Overall, he's a great guy.

Mr Koehn or BDK as we used to call him was one of the best teachers at OHS. He always had time to help a student with Chem. He is also very easy to talk to.
