Greetings! I’m Your Instructor, Dave Langer.

Author | Microsoft MVP | LinkedIn Top Voice

I’m not your typical data science instructor. I believe ANY professional can (and should) build DIY data science skills. To succeed in this mission, I have to do one thing and do it well:

I have to make learning data science fun.

Yes, you read that correctly.

I won’t lie. Many find the idea of applying data science intimidating. It shouldn’t be. It’s a skill like any other. You get better with practice.

Making learning data science fun makes getting started less intimidating.

You’ve got this if you want it.
