Truly teaches not just math, but also how to think. First I hated him, but then I realized how much he cared about his students, and how much respect he deserves. He is an amazing teacher and probably the best math teacher at Mater Dei! Awesome man, you're lucky if you get to be his student, your world will be enlightened.

A good teacher, but you have to actually do your work. Pay attention, and you'll get the grade you deserve.

Mr. Lieblang is a god among men. He taught me skills that I'm still using in university math classes. I don't think I'll ever have that good of a teacher ever again. PEMDAS

He's hard, and he's really good at what he does. I know people who have gotten C's and D's, but still don't regret taking his class. Not just a great teacher, but a great guy.
