Tom Root is an entrepreneur who originally envisioned Zingeman's Mail Order and started it up as a co-partner and then founded the Maker Works as his second business.

In 2002, Zingerman's Mail Order and Zingermans.com merged and Tom took on the role of Chief Financial Officer of the resulting business (known simply as Zingerman's Mail Order). As CFO, Tom has championed open book management and taken the lead on educating staff about the financial ins and outs of the business.

In 2004, Tom was introduced to the concepts of Lean Manufacturing popularized by Toyota. Building on his experience with open-book finance, Tom worked to bring the philosophy of continuous improvement and waste elimination to Mail Order. For many years, Tom has been practicing Lean thinking through process improvement, class development and teaching.

In 2008, Tom was inspired by the financial crisis to start Maker Works. Maker Works is 11,000 sq ft manufacturing facility that is operated like a health club. Individuals or businesses purchase memberships to have access to high-tech tools like laser cutters, 3D printers and CNC plasma cutters. The mission of Maker Works is to democratize the tools of manufacturing to foster job creation, community and self-sustainability.

In September of 2014, Maker Works celebrated its 3-year anniversary. It has attracted more than 700 members, added 16,000 sq ft of tenant space and played a role in a handful of start-ups including Sight Machine, a venture funded computer vision start-up.
