awesome math teacher, obsessed with mma, and has the uncanny ability to sneak up on anyone like a ninja without a sound
I loved Mr Lang. He helped me understand and pass geometry with a B! Awesome teacher and person in general!

Mr.Langrehr's great at what he does. He's a thorough teacher and you'll learn a lot if you pay attention in his class.
THE BEST ENGLISH TEACHER I'VE EVER HAD!! Every 9th grader who comes to Concord High needs to begin with Mr. Langrehr as their english teacher. They will go far.
Mr. Langrehr is good at teaching. He doesn't give much homework or work but his test are hard. He loves running and talks about it all the time.
