Best teacher. Unfortunately he's retiring this year.
Mr. Alcosser is the best teacher I've had in my entire life.
There's a bunch of raving review on him on this site... and for good reason!
nuff said alcosser is the best. just talk lots/ask questions in his class
He's the Math god..................................
Best Calculus teacher in the world. If you have him and you work hard, you will get a 5 on the AP test fsho
Best teacher in the whole universe! I had Mr. Alcosser in 1994-1996 for Calc AB & BC. I've never had any teachers like him who has such a passion for teaching even at college. He was the teacher who inspired me to become a math teacher. I want to be just like him to be able to help students with math. I am so blessed to be in his class, because it totally changed my life. Thank you Mr. Alcosser! - Terry at Mathnasium of Diamond Bar
I graduated college in 2009, and Mr. Alcosser was the most influential math teacher I've had in my life. He not only taught calculus, he taught us how to make a good impression, how to shake hands and look someone in the eye. He cared for us more than just a teacher. He has my utmost respect. :)
Mr. Alcosser is an amazing teacher. He is strict but pay attention and you get excellent results. I was fortunate enough to have him as my teacher and I benefitted so much.
Alcosser's an aMAZing teacher, and if you get him as a teacher, consider yourself lucky :) He's passionate and knowledgeable about what he teaches, and no worries-you're in good hands for the AP test.
One of the best teachers at DBHS and also in the nation. He has a lot of pride that he is rated as the best calculus teacher in the country. Despite that, he is very funny and his class is very chill.
AWESOME TEACHER! always talkative and keeps you awake! Helped me get a .. FIVE! Having him again in HL
Mr. Alcosser is probably one of the best teachers you will ever have. He's smart, funny, clever, helpful, and just all around a fun guy.
The best math teacher. I wish there were many more of him.
Mr. Alcosser is the best! He makes everything easy to understand and homework and tests are weighed equally so getting an A isn't hard. He's big on integrity, so don't cheat!
best teacher out there! he makes sure to keep you awake at all times. sometimes annoying with the movies though, stopping it one second after the last spot we were at..
an awesome teacher who can teach math and make it fun and interesting at the same time.
He is an AMAZING teacher. Honestly cares for his students as his own. Word of advice: take this ap test! He embarrasses you otherwise lol! Best Mathmatician in the Nation! No Joke! Father of Calc!!!!
It's been years since I've had him, but he was one of the best teachers I've ever had. I had him my senior year for 6th period, and it was a joy to end my day with him.
BULLYYYYYYY THIS IS FOR YOU! Very great teacher. Love him
he is the best math teacher, possibly the best teacher, out there. He really cares about students, genuinely. no joke. and he's so funny&cute! I absolutely love him and will truly miss his class.
SERIOUSLY THE BEST MATH TEACHER EVER!! THIS IS SOOOOOOOOOOOOOOO EXCITINGGG!!!!!
If you want math or engineering as your major, definitely pray for this guy to be your teacher. One trick you might use- take IB, you'll get HL1 math= calc2= alcosser, drop IB, u mite still have him.
The best math teacher and ap grader in the whole world. He is willing to stay afterschool to tutor you.
Mr alcosser rocks! Always is helpful and very nice to students. His class is extremely easy to obtain an A while you understand the material extremly well. Take him if you can!
THIS ISS SOOOOOOOOOOOOOOOOOOOOOOOOO EXCITTING! BEST TEACHER EVER! A++++ WOULD BUY FROM AGAIN!
one of the best math teachers out there. makes everything easy and makes sure every student in the class understands the material. not only is he a great teacher, but he is also very fun & lively! (=

the best teacher ive ever had and he makes everything seem so easy
mr. alcosser is one of the best teachers i've every had! he is funny and energetic. Not only does he make each class fun and "exciting" he also teachers well.
If you have the opportunity, definitely take Alcosser.
T H E best teacher I have ever had (don't remember kindergarten teachers). Funny + Good teaching = Best
best teacher i ever had there is nothing bad to say about him
Awesome calc teacher, makes the subject interesting and easy to understand. Now go get a 5
good teacher yes, but not so good person. has an attitude problem. he needs to check himself. needs to be reminded that students aren't his kids.
This guy can teach. Best teacher at DBHS by far next to Mr. Sismondo they made a great team.
He is a GREAT teacher. I understand BC material better than I would have with any other teacher. I totally recommend taking him
Mr. Alcosser was my teacher in 1981-82 (co-taught w/Mr. Sismondo) at Walnut HS. It's great to see how well he's still doing (according to all the great reviews)
best teacher in dbhs. you guys all should take him :)
the greatest teacher at dbhs... his class is the only class i miss from college.
