Great teacher, goes out of his way to help you learn and understand.

Dr. Keller (aka Dr. Duke) is the best! His class is hard, but his is the most knowledgable in finance, real estate, accounting, and business. He also gives away money in class...must be nice to be rich.

The Best teacher at PBCC period.He teach business and Accounting. If you fail something wrong with you. cool guy. He love his red mustang convertible, he will talk abou it a lot.

He is an awesome teacher-gives sample tests and lets you use your notes on the tests. Makes the class fun- no term paper at the end of the semester-need i say more?!

the class was a breeze but you learn so much!!! such a great teacher!!!!

This teacher is the bomb...sooooo funny and helpful. Def. best teacher at PBCC

Keller is seriously the best teacher i've had @ PBCC all together.. I am finishing next semester he will keep the class interesting with his stories and jokes and ask him about "the walk" and tons of other things that make the class worth looking forward to.

He is without a doubt, the BEST teacher at PBCC, there is no question, no doubt, nothing that anyone can say that is bad about this guy. He's the funniest person alive, and honestly cares about his job. He isn't stuck up or snobby.He's even a family man, ask about B1,and B2g.

Best Teacher at PBCC. He tries very hard to help everyone understand the material. I recommend taking his class every chance you get.

Not only the best teacher at PBCC, probably the best teacher anywhere. I took him for intro to business and bookkeeping, and I am going to take his class for small business management. I highly recommend him.

Very funny

I loved this professor. I was surprised that 90% of my class had him before as a teacher & liked him so much they took another one of his courses. That tells you a lot. Apparantly he teaches several different subjects & I am signing up for another this semester. If you want an easy "A" take his class. He is so funny & always willing to help you.

Great teacher, easy to understand and you can ask questions during his lectures. Keeps thing light and fun with his jokes and life experiences. I will be taking more of his classes. Thanks Duke!!

I took him for intro to business. He is one of the teachers that definitly teaches you the information you will use in everyday business life. Extremly funny, and a gret well rounded guy. Always cracking jokes on himself as well as students. Test are almost identical to pretests. Would go out of his way to help you. I Would recomend him to anyone.

Duke is a student's instructor. He make the class fun and interesting, we have had alot of fun during class. Anyone interested in starting a business should take this class first.

He is very very funny.......extremely hard to get anything but B or an A. He always willing to help.........and i actually learned in his class..............highly recommend.

Duke Keller is a sweetheart. He is such a caring, funny, helpful guy. I have taken a couple of his classes and he is very fair. He makes class fun with his jokes and although his classes are extremely easy, you still actually learn so much form them. It's a shame there aren't more professors like him. He makes going to school fun. A++++

I think he is an excellent teacher I have taken two of his class and is signing up with him for a third. He is very helpful and will to tutor you so that you can be successful. I would recommend him to everyone.

FANTASTIC! He makes sure that the class is kept engaged, that all students understand the material, and he tries his best to keep things interesting and fun. One of the best professors I've ever had. I would take any of his classes!

This guy is the real deal! He's funny (or try's to be) he's fair and he cares about his students. You learn a lot and he has so much experience and wisdom, but do not ask him about his "Jacket" -he'll never stop talking about! Overall, even though I did not get an A, I rate him one of my BEST professors I ever had! Take him, you will be glad u did.

Great guy! Love his students. His tests are hard but they are exactly on what he gives you on your study guide. He makes class fun. He is a great teacher!!

Duke is the BEST teacher! Makes class fun, tells oyu what you're going to be tested on. Take him for as many classes as you can!

Duke is awesome. Caring, Funny, Helpful, everything you'd want in a professor. Took a dry subject and made it fun /interesting. Has real world experience and knowledge not found in textbook. Loves the military veterans in his class,likes to poke fun at any service other than the Air Force. Wish all professors were like Duke Keller.

Duke is awesome. He is caring,helpful, good natured and passionate about his teaching. He takes a dry subject like bookkeeping and makes it fun and interesting.

LOVE, LOVE, LOVE HIM! Can't wait to take another class with him! He's soo funny, explains everything with personal examples which makes the material so much easier to understand!

Professor Keller is amazing. I have taken other courses with him and have learned so much about business. His methods of teaching, which include, real life scenarios and lectures from the textbook helps me visualize the material. He has a hands on approach to teaching and it has made me successful in my business studies. I have recommened his class

Sweetest old man. Very helpful, explains everything using real life examples. Tests aren't hard (sometimes lets you use notes) but you do need to know material. Textbook & attendance are mandatory & usually keeps you the entire class time but he kept class fun & interesting. I would take him again!

Very good teacher. Tries his best to help you to pass course. I highly recommend him.

Very helpful but confusing. He's pretty old and knows topic but will miss and you have to correc then jokes and says he was seeing if we were paying attn. Mostly handouts that I found confusing; double sided flipping back and forth. Don't miss or you will get behind.

He is a very sweet man, cracks a lot of jokes but keeps the class interesting. He explains everything with real life experiences which helps a lot of people understand and relate to the material. Takes time to help his students and makes sure everyone has an understanding of the material. Offers tutoring which is great!

Funny man. Cracks a lot of jokes but keeps you interested in class. Gives real life examples that help you understand the material. Will make sure you understand the material. Offers tutoring. Test reviews match the actual test. I would def take him again. He is an amazing teacher.

PROF KELLER IS A MATURE PERSON THAT CARES FOR HIS STUDENTS. HE VOLUNTEERS HIS TIME ON SATURDAYS TO ENSURE THAT HIS STUDENTS LEARN OR REVIEW THE MATERIAL. HE IS A FAIR PROFESSOR WITH MANY YEARS OF EXPERIENCE AND KNOWLEDGE. I REALLY RECOMMEND HIM AS A PROFESSOR FOR ACCOUNTING

Best prof ever, he's funny keeps the class interesting and keeps you awake especially when you're taking a night class. If you fail his class you should go back to elementary school. Got an A & got out of class 2 wks early final is optional. Wish he teached more classes. AWESOME!!!! Take him you won't regret it

Very helpful teacher makes the extra effort to ensure everyone understands material. Would Def take another class with him.

Great teacher! Very knowledgeable, keeps class interesting and easy to follow, always helpful and funny. Highly recommend.

He is a very nice professor and he gives reviews which help a lot with the tests...he is easy going and always willing to help you improve your grades

Amazing teacher. Absolutely the funniest teacher I've ever had. Reviews the subject matter extremely well and provides very relatable scenarios to help you understand the material. Tells a lot of interesting stories, too.

I took Business Math and Intro to Business with Mr. Keller (Duke). He is very friendly. funny, and knowlegeable in the topics he teaches. He goes the extra mile to help you understand the material. I think you would have to actively try to fail his class.

TAKE HIM!!!!!!He is a wonderful,funny ,and smart professor.He gives you 200%!!! Ask him about his caballeros jacket! :)

Professor Keller is one of the best instructors I have ever had! I've had him for 3 courses already and am taking another 2 of his courses next semester. I love his style of teaching and the fact that he tells 'real'stories to bring the material to 'life,' while keeping the class involved. He teaches exactly what he tests. Light-hearted,funny& warm

Professor Duke Keller is the best teacher I've ever had the pleasure of learning from. The class itself taught me a lot, but most of all, Duke taught me the most. I've taken 3 of his courses already & am excited to take another 2 he's teaching next semester! If you want to learn from the best - take his classes! tests are what's taught; xtra credit

Four thumbs up! Awesome, funny, knowledgeable, and makes learning a blast..You'll absolutely adore him!

Nicest professor at this college, bar none. Caring and inspiration and REALISTIC. TAKE THIS PROFESSOR!

I Took him for "Fundamentals Enntrepreneurship". Amazing Professor! He is a lot of fun... i love him like an uncle..He tells you stories,that relate to the course. This is my 2nd time taking him and I am now ready for the 3rd class. Take him you will not regret it....:)

greatest professor ever, hands down!

Greatest, most Awesome Professor ever, hands down! He will not waste your time; covers what he tests on...just participate!! :)

I took Mr. Keller for bookkeeping and intro to business, and he was so interesting and helpful, I would take him for all classes if I could. He helps out anyway he can.

best of the best - can't go wrong!

STOP! Make the right choice and take his classes.Last semester teaching fall14. It's endless of how great he is. Look at reviews. It isn't a free ride by any means. You have to do the work to get that A. Don't miss the opportunity. My educational plan is built around his classes. Trust your instinct and sign up NOW! You will be thankful. Study hard

Professor Keller, he is one of the best teacher. at some point complicated to understand but if you study hard you will understand it. he gives out extra credits to help you with the grade.

Professor Duke is THE BEST professor I've ever had! Took him for bookkeeping & passed with a perfect score! Way different from the teacher I had for ACG2022 that I almost failed twice! He simplifies everything and gives you tons of practice so by the time the test comes you are prepared enough to get a 105! TAKE HIM BEFORE HE RETIRES!Very nice man!

I wish more professor's were like him. He's a great teacher likes to make sure you're learning, always gives out study guides and on Saturday's morning he's available for tutoring, class is very interesting and you always learn new things not only the subject but life as well. Perfect teacher!!!

He is the best teacher i ever had.he goes over and beyond the class time and perform tutoring free of charges in campus so student can improve their grades. i got good grades in three classes because of him and his incredible teaching technics.thank professor you are the boom!!!!

One of the best teachers I ever had and he is so helpful.

Amazing man. I had him several years ago and he will always be my #1 best college class experience. Thank you for being one of the rare ones that can teach and also inspire.

Best professor in PBSC, very funny, knowledgeable and helpful, it was always a joy to attend his class, Prof. Keller is the best!!!!

Seriously one of the best and most helpful teachers I've ever had, I passed with an A. He is genuine and really cares about his students. You are crazy if you don't take this teacher!! He also goes over study guides multiple times so you will pass the test. Truly a great teacher and I really learned a lot.

He is the best teacher I have had in a long time. He is educated the business world, and he gives great examples to help you remember the material. He gives you handouts and tells you what will be on the test. There is always opportunities to receive extra credit on test, which is nice. I would recommend him for any class you have to take.

Professor Keller is an expert in his field and chose to become a teacher for an obvious reason. He is a awesome, gifted and very down to earth - not to mention a stand up comedian! I have learned a tremendous amount in the few short weeks of attending his class. SO lucky to have him for my first college class in 36 years!

He is very helpful, he cares about his students, he is respectful He does tutoring and gives you all the time you need.

Hands down the most helpful professor that you will ever find. GREAT human being. Please take him if you can.

Best professor by far at Palm Beach State!! Even takes time out of his busy schedule to come in on a Saturday to tutor you in different classes of Business like Book keeping and Accounting If you have the chance you need to take him

I am 75% done with my AA and Professor Duke is BY FAR one of my top 3 professors. We all know how tedious it is to find a good professor and he is a definite gem at Lake Worth Campus. Take him, you WILL NOT regret it! Tests are open NOTE, whatever you write, you can use. LOTS of extra credit, attendance is mandatory, but class goes by fast.

One if the greatest professor's I have taken. Extensive reviews for exams, open notes, and plenty of extra credit given. Only strict about attendance. No access code is required for class; no homework, only 3 small papers (35 lines). Drops lowest test score as well. Wish I could have had him for all of my courses!!

Prof. Duke is the most awesome Prof I've had and very knowledgeable and passionate about what he does. He truly loves his students and makes the class fun. Just take notes during his reviews on the study guides and show up to class you will do great. If you every second guess about becoming and entrepreneur, take him and you'll find your way.

Professor Keller The best teacher in Palm Beach State College, I never Imagined being in such fun business math . Sweet, funny, knowledgeable, and willing to help students with tutorials according with your time. He cares, and make sure that you are well prepared for his exams. Your grade will be an A.I strongly recommend my favorite Professor.

Definitely one of the very best teachers I've ever had. Makes learning fun.

Excellent professor, the best business teacher at PBSC!

Has many personal experiences. Wants all his students to pass his class , so he is very helpful and will go out of his way to help.

best teacher ever

Great professor, hes very kind and knowledgeable. Both tests and papers are easy. Though some of the questions are simple thats its hard to come up with 35 lines

Keller was an amazing Educator, far from a teacher. He knew how to engage you even if you are the quiet one in the back of the room. Many many stories about his youth and career, for he was a very successful man. Most important, he loves what he does, maybe a little bit more than his own toy soldiers. As long as you're taking notes, you can't fail

Super kind professor, very knowledgeable and to the point. Lots of life experiences. Realistic and super funny in a very endearing way. Youll always be engaged and the class goes by super fast! Easy stuff reasonable study material ! I used book in every class too, and he follows the book well but you can barely tell hes following the text. Great!

Amazing professor. Dukes class is enternatining and educational. Ive never met a professor with more jokes, and stories as him. He genuinely cares for his students and what he is teaching us. Take good notes and you will get an A. You will not regret taking his class.

Professor is hilarious and a joy. Uses his own experience to clarify terms in an easy to understand manner. Gives study guides to follow lectures. Take good notes, use the guides and the class is memorable and easy. Gives lots of extra credit but you probably will not need it. A few easy papers to write. Would take additional classes w/him.

HE IS VERY HILARIOUS AND JOKES A LOT WHICH MAKES THE CLASS FUN AND NEVER BORING. HE IS VERY CARING AND PASSIONATE ABOUT TEACHING AND MAKES SURE THAT YOU UNDERSTAND THE WORK GIVEN. THE HOMEWORK IS NOT HARD. TAKE THIS CLASS!!! YOU'LL BE CRAZY NOT TO. I WISH ALL MY TEACHERS WERE LIKE HIM.

Duke is an awesome professor. Very entertaining lectures, always making us laugh, uses great study guides, if you take good notes this will be an extremely easy A.

Easy A. Easy grader. Well mannered professor. His lectures are extremely enjoyable. Has fun activities and is always in high spirits. Loved his class. We need more professors like Duke! Such an amazing person overall.

Professor Duke was amazing. I enjoyed this class, so entertained at the point you don't realize you are learning. Time in the class run fast. Thanks to "Rate my Professor" because I took the suggestion from here, and I didn't regret. If he teaches other subject that I need to take, I wouldn't think twice. Experience, knowledge and fun together.

Professor Duke is AMAZING. As long as you pay attention to his lectures and write down EVERYTHING you'll do great on the test. You're allowed to use study guides on all tests and he will go over test material many times. If its not on the study guide its not on the test. Only 3 papers to write and all opinion based. Super sweet and fair professor!

Favorite professor on campus!

Best professor I had. Some people just think they are teachers, Professor Keller is that and much more. He is an amazing human bean, a respectful gentleman, a sweet man, a professional from head to toe. I hate math, and he made the concepts so clear it seemed easy. All you have to do is listen and pay attention. I miss professor Keller.

Donald Keller is an experienced and intelligent lecturer. Although his examinations are difficult, his knowledge and insight of the business world will stick with students for the rest of their lives.

Great professor, wants to see his students succeed. Make sure to stay on his good side and don't fool around in class. Study guides before exams that help immensely. Great overall person.
