About David Arenstam

David Arenstam was born in the foothills of the Berkshires in Massachusetts and raised by the sea in Plymouth, but spent most of his adult life by the shores of the Saco River in Maine. After starting and running a small data processing and software firm for nearly 20 years, he found his real passion and voice in teaching and writing.


Never one to really sit still, over the years Arenstam studied mathematics, literature, education, writing, and many forms of technology.

Education, teaching, and writing now fill his days. He is a proud faculty member of Thornton Academy and writes regularly for local newspapers, magazines, and online media companies. A lifelong student, he continued to study and recently (2015), he completed a graduate degree in journalism at Harvard.

As he often tells his students, “the world just might be the greatest classroom you’ll ever enter – take a minute and look around. You’ll be surprised at what you see and the lessons you’ll learn.”
