About Dennis
Do you struggle to move beyond basic data entry in your daily work? First sessions start by auditing your current workflow to identify major bottlenecks. We then build a plan using your specific files to ensure the learning stays relevant to your goals.
You will gain proficiency in error handling, INDEX and MATCH functions, and data validation techniques. The curriculum covers SUMIFS, COUNTIFS, and advanced text functions to clean messy datasets. I provide a free practice workbook with exercises to reinforce every concept after we finish. My goal is to simplify these tools so you feel confident managing your own spreadsheets immediately.

Completing a Master of Science in Data Science from Columbia provided the foundation for my 10 years of experience in the fintech industry. Data analysis is a practical discipline that demands precision. I have helped countless individuals navigate complex spreadsheet structures during my career. My teaching approach focuses on the hard mechanics of Excel to ensure clarity.
Coding for analytics and the math behind the logic remain central to my method. I am here to help you solve problems using real business data instead of abstract exercises.
