Greg studied mechanical engineering and helped develop the 2cam rock climbing anchor as an undergraduate in Colorado. He spent two years as a stress analyst at Boeing working on all of Boeing's commercial airplane models. He then returned to graduate school to study cartilage mechanics. He is now with W. L. Gore & Associates as a product manager in the disk drive filtration group. He balances his engineering experience with creative works in sculpture.

In 2009, Greg started the company whitevan with Dennis Beach to design, manufacture, and sell simple products. Please visit the whitevan.org site if you would like to purchase some of the products Greg has designed.
