Kevin was a great instructor and very knowledgeable. I learned a lot. Thanks!

Sean Donnellan was awesome. Should I ever need to take more courses or a refresher on data analysis; he will definitely be the teacher I will look for.

Mr. Donnellan was extremely knowledgeable and took time to answer questions and provided great demonstrations. The class pace was also great and I felt that Mr. Donnellan cared ...

I started this class in June 2021 and this class was a better version of that class.

Sean Donnellan is not only an expert at Data Analysis, he is also a fantastic instructor. I learned more than I expected and will be a better employee because of it.
