Best class I have ever had. No exceptions or caveats. He taught me more about history, patterns of change, American Humor, love, hate, war, peace, and why America always seems to be on the edge of its demise. He treats every student like an adult. His class is based off text-book which is guides it. So lucky to have him, hope he has a great retirement. He earned it
Literally the best teacher I've ever had at LHS. He knows everything about US History which makes his classes even more interesting. Mr. Kollen is da bomb (make sure you do the notes though)
coolest teacher ever. easy, funny, and awesome in general.
Amazing teacher!! he makes his lectures funny, so you remember them well. Knows his stuff, and always friendly.
One of the best teachers I've had at LHS. Cares more about what you're learning than your grades, and he's a friendly guy. I was glad to have him and recomend him for those passionate about history.
mr. kollen is a good guy. get on his good side and you'll have a great year, an easy grader for ap students, great class
Made everything so clear and easy for learning. Love him!!!
I loved his class, made everything clear and really helped out on the US AP exam
I LOVE MR KOLLEN! he is the most clear, reasonable, interesting history teacher out there. he is awesome.
In a word, adorable - love the giggle... very good teacher, lecture format gets a little monotonous but you learn soo much (so ultimately its worth it).
Mr. Kollen was the greatest History Teacher I ever had. I now teach High School US History and if I could be half the teacher he is I would consider myself lucky.
Awesome teacher. And you won't find a more dedicated Sox fan/pessimist.
mr kollen is the best history teacher i've ever had. i liked his attitude.
Mr. Kollen makes everything interesting, efficient, and fun, he's awesome.
Mr. Kollen is awesome. He knows how to teach. You learn on your own and discuss things in class, he's hilarious. My favorite class of all time, AP US History.
Hilarious, interesting and knowledgable... can it get any better then that?
More knowledgeable, funny, and unique a teacher than any I've had. He really makes history fun and relevant; awesome guy.
One of hte best history teachers i know. Loves his job and that makes us love his class
Probably the best history teacher I've ever had. So entertaining and knowledgable.
The best history teacher ever. The reason im taking the courses that im taking next year
What a great guy. We'll forgive him for being on the Bush side-...maybe. No, really, a really funny teacher. You'll learn a lot and it's fun.
As long as you do the readings assigned each night, you're all set
Mr Kollen has to be one of the best teachers i have ever had. possibly one of the quirkiest too, but that makes class so much fun and soooooooo funny!!
Phenominal Teacher - tough to find better history teachers than this guy.
Probably the greatest AP U.S. History teacher the Eastern Seaboard has seen.
