About Us

Bladewerx began in 2001 in the field of radiation detection. In early 2006, the company began providing shielding materials under the trade name of Shieldwerx. Specializing in neutron shielding, Shieldwerx has brought innovative solutions to the industry in the form of custom configurations and specialty products. We have provided quality shielding products to the DOE laboratories as well as many research facilities around the globe.

Throughout the years, Shieldwerx's high-quality line of shielding materials has had a few different looks.  The product line began as Reactor Experiments over fifty years ago in California. With the next transition, it joined with our family as Shieldwerx.  After a few short years, we completely integrated the products and services into the Bladewerx family, joining its line of cutting-edge radiation instrumentation.

Meet the Team

David Baltz

David is the founding father and chief technologist of Bladewerx, bringing to the table over forty years of experience in software design and development.  He was a design engineer for Thermo Scientific (formerly Thermo Eberline) for 13 years before leaving to start his own company. He was the founder and president of Metalman Corporation, an innovator in the mechanical computer-aided-design market, which he ran for ten years. Before starting Bladewerx, Mr. Baltz served as a consultant to Thermo Scientific, spending three years developing the instrument and client software for the state-of-the-art Thermo Eberline Alpha-7 CAM.

David is not all computer genius…

He is also a talented hazardous-adventurer. For dB, living on the edge has meant years of enterprises in hang-gliding, cycling, CrossFit, 4×4 off-roading, and has been rock climbing for almost 50 years.

Don Hanna

Don is the fearless leader and CEO of Bladewerx, with more than forty years experience in design engineering, engineering management, general management, and rock’n’roll enthusiasm. For twelve years, prior to joining Bladewerx, Mr. Hanna was President of Thermo Eberline and two other Thermo Electron subsidiaries. He was responsible for businesses ranging from a startup to an industry leader with products that include bioanalytical instrumentation, monitoring and detection systems, and industrial temperature control equipment.  Don’s education as an electrical and nuclear engineer (B.S./M.S.) coupled with his professional experience in organizations ranging from a few employees to hundreds of employees brings to Bladewerx a solid technological knowledge base in the radiation protection and measurement field, complemented by hands-on management and organizational experience.
