He help me with my troubleshooting at work and turned that into a valuable tutoring session. I will highly recommend David. He is also an excellent tutor and really want to see his student succeed.

Perfect! I had a terrific first class with David! I found David to be an articulate, thoughtful, and engaging teacher. He's clearly a subject matter expert in his field and is passionate about sharing his knowledge of all things data analytics with others. As a beginner learner in both SQL and Excel, David was able to highlight and explain key concepts that were overlooked in my data analytics course. He helped fill in some gaps that I didn't realize I was missing. I would definitily recommend David to anyone who wants to further their data analytics skills and I look forward to my next lesson with him.
