Welcome!

My name is david massie.

“Mister Mathie” is just a playful moniker given to me by a clever former student. I’ve chosen it as an appreciative nod to all the amazing kids I’ve gotten to know.

You may know me personally or by reputation from my many years as a high school mathematics teacher at Carol Morgan School of Santo Domingo.

Regardless, I appreciate the opportunity to introduce you to both my tutoring services for high school mathematics and to my open-access library of resources.

Let’s math!
