Lee is a master machinist and woodworker from California, now living in Grand Rapids, Michigan. He downloaded Stewart Coffin's The Puzzling World Of Polyhedral Dissections from this web site along with the other reference material of Stewart's and started making puzzles. He has adapted some of Stewart's jigs into a precision machined version that allows him to produce extremely precise puzzles.
 
His puzzles are among the best. Lee has the following to say about himself:

I have had a passion for woodworking all of my life. I was pursuing a math and computer degree at Harvey Mudd College when I read Stewart Coffin's The Puzzling World Of Polyhedral Dissections and found inspiration to follow a different path in life. About a year later I invested in a small workshop and began making some of Stewart's rhombododecahedral puzzle designs. That was one year ago. I am 22 years old now and puzzle making is my only job. In the next few years I hope to take Coffin's work further, writing more about the underlying principles of his puzzles, as well as woodworking techniques for making them. I am also interested in writing computer software for modeling, designing, solving, and analyzing puzzles with non-rectilinear geometry. This will probably be a long term project.
