OES was founded with a single focus on servicing industrial controls. Within a year the company expanded its focus to include design & manufacturing of control systems for large custom applications and design & manufacturing of circuit board level electronic controls. Our passion and ability to problem solve in the Tier One industry has been the foundation for success and client loyalty now well past our silver anniversary. OES grows and prospers, by hiring bright, energetic individuals and providing challenging opportunities for them to develop. OES reaches the world from our international offices in Canada, the United States and China, and through our well connected network of representatives.
