David Brode is a financial modeler in Boulder, Colorado. An avid puzzle solver, he found this blog while searching for puzzles online. He was intrigued by the puzzles and was curious to see a kindred spirit in Colorado. David called to introduce himself and I enjoyed meeting him in person a few weeks later.
David publishes a monthly newsletter about financial modeling on the website of his company, the Brode Group. I am flattered that his latest newsletter discusses some of my puzzles, and compares them to Zen koans.
