I help ANY professional or team have more impact using data. Analytics demystified.

👉 WHAT I DO: I help teams and organizations develop and apply real-world machine learning forecasting skills using Python and Python in Excel.

⚙️ WHO I HELP: Every type of organization will benefit from better forecasts, including (but not limited to):

🏛️ Financial Services
🏥 Healthcare
👩‍🎓 Education
📺 Marketing
📊 Finance
💻 IT 

💰 WHY IT WORKS: In modern organizations, many external factors impact forecasts. These factors include holidays, promotions, capital investments, weather, and global economics.

Machine learning forecasting models can incorporate these external factors to produce more powerful forecasts than can be achieved via commonly used techniques (e.g., Excel's FORECAST.ETS() function).

✅ HOW I DO IT: I work under two operating models depending on your business needs:

"Done with You" - This is a coaching model where I train your team/organization and then help them successfully apply what they've learned.

"Done For You" - This is a consulting model where I do the work on your behalf.

Regardless of the mode, I focus on the nature of your business problem first and foremost. 

Before I write any code or train your team, I partner with you to develop an understanding of your business. With this baseline knowledge, I then bring my 14+ years of analytics and data science experience to the engagement. 

I can use Python in Excel or Jupyter Notebooks - whichever works best for your situation.

Woohoo! My book has received its first Amazon review. I had one goal for writing Python in Excel Step-by-Step. This goal might seem crazy to some:

To teach ANY professional the Python foundation they need for analytics and the AI-powered future of Microsoft Excel.

I packed the book with many examples of how everyday Excel knowledge translates to Python. The goal was to make learning Python easy and fun for Excel users.

**BUT**

As an author, you never know if your efforts were on target until the book gets into the hands of real people.

As you might imagine, getting this review early in the book's release gives me hope that the book will help many professionals learn the Python foundation they need to:

Unleash the power of their data with analytics.
Partner deeply with the Copilot in Excel AI.

2026 is off to a tremendous start.

Stay healthy and happy data sleuthing!
