Team

Vivian Allen

Vivian Allen

President

Vivian brings a decade of precision injection molding expertise to the industry. She inherited her desire to push traditional boundaries of what customers believe is possible in manufacturing from her father, who founded SigmaPro in 1999. As an honest broker and servant-leader, she possesses a relentless drive to continuously level-up the business and earn customer devotion. Vivian worked in federal contracting, HR and business management roles prior to becoming the literal and figurative boss at SigmaPro. According to her three children, “Mom is a master cooker.” So yeah, she’s a master chef, too.

A creative genius and perpetual tinkerer, Chris began as a hobby 3D printer and CAD designer who now delivers design and prototype input that surpasses the quality found in production-level additive manufacturing elsewhere in the industry. He’s held almost every role there is in 10 years at SigmaPro, from document control to video production. Call him a jack-of-all-trades who ended up mastering each one. His hobby is hobbies, including building custom electric guitars, woodworking and playing multiple instruments. Like everyone else here in the Lone Star State, Chris believes he smokes the best brisket in Texas.
