“Had Dr Winston in b-school at IU. Best class I had by far. I am a huge believer in Dr. Wayne Winston and his ability to find unique ways to utilize Excel for real world business analysis!”

“Lectures are short, but in-depth enough to get a good understanding of the the material covered. I love having the ability to go to the working files and practice what I’ve learned. Best of all, I can go at my own pace and go back to review information later. Great course!”

“Being able to have the before and after files makes all the difference. When I would get stuck, I could get the finished file and see how the formulas were working. Then I could go back to the video and have a more in depth understanding.”

“If you need to power up your knowledge of Excel and train yourself in the most useful and powerful tools, this is the course you need. It’s easy to follow, straight to the point and very practical. It’s great for business people that don’t have time to waste in confusing theory and explanations.”

“Absolutely exhilarating to sit in his class two full semesters. In addition to the excel skills, loved the mental stimulation that came from tackling some real world problems in Excel. We were fortunate to have him at Kelley School of Business MBA Program. Highly highly recommended!””

“Dr. Winston was one of the smartest professors I had in grad school! Totally enjoyed his class.”

“Took it. Loved it. I improved my Excel skills a quantum leap. I’m 64 years old, never had a spreadsheet course in my life, and am now doing crucial analysis of our pharmacy data, some of which is tens of thousands of rows, with columns in the double alphabet. I read a few chapters of Wayne’s book, but this course brought it all together for me. If I can learn this, anyone can.”

“Best professor I ever had. I’d take him for anything and think he could teach anything but Decision modeling in spreadsheets was also best, most relevant (for a finance major like me at least) class I had as MBA student. Hope you are well Professor Winston!”

“Awesome professor! Loved his classes!”

“Was one of the best professors I ever experienced. “

“I had the privilege of sitting in Wayne’s class years ago and it greatly helped both my understanding and teaching of Excel. He’s awesome!!!”

“I’ve enjoyed the training very much. I’ve been using excel for many years, but with Wayne’s training, I’ve been able to do things quicker which saves me time and allows me to complete my projects faster. I recommend this training. It’s awesome”

“Loved your MBA classes when I was at Kelley – still use some of the stuff you taught me everyday! I’m definitely signing up for this as a fun refresher – thanks for offering it!”

“Love Wayne Winston! Best PROFF Ever !! “

“When I started at Kelley, I didn’t know a thing about Excel, as I was a copywriter. You turned me into an Excel geek, for which I am forever grateful!”

“My B-school quant professor literally wrote the book on Excel. He helped even the poets among us discover the elegance and power of data. Go Wayne!”

“You were my favorite B-school professor. I just signed up for your course as a refresher.”
