Our Leadership Team

The people behind the boards.

Founding leadership from 1982 — Jerry Winfield, Sandra Winfield, Robert Burckle — and the engineering, manufacturing, and programs bench in Grand Prairie, Texas.

J

Jerry Winfield

Founder and Chairman

Started the company in 1982 from STD Bus design work in industrial electronics and petroleum. Still the through-line for temperature-rated industrial boards and the culture that kept people on the bench.

S

Sandra Winfield

Early growth and operations

Joined in the first expansion years and helped turn a specialist STD Bus shop into a standing embedded-computer business.

R

Robert Burckle

Early growth and programs

Came aboard during the early growth of the company, with a long record delivering complex technology into commercial and defense programs.

M

Mara Ellison

Chief Executive Officer

Owns strategy, the product calendar, and customer satisfaction as markets and silicon change. The job is growing the catalog without breaking the life-cycle promise.

O

Owen Hart

Design engineering

Liaison between schematic, thermal, and the floor. Product development reviews only close when manufacturing can actually build the drawing.

L

Luis Ortega

Manufacturing

SMT, process, and box-build in Grand Prairie. Aligns engineering releases with the line so a new SKU is a traveler, not a surprise.
