Who We Are

About Our Company

TEIM Design, PLLC can trace its origins to a small consultant engineering firm founded in 1961 in Oklahoma City named Howard L. Russell and Associates.  As the firm added partners, the company name became Russell, Gravlin, Douglas and Cornell, Inc.  in 1970.  With an expansion into transportation design in 1997, Douglas, Davis, and Gravlin changed the company name to Triad Design Group, Inc.

In early 2020  Joe Davis, Josh Johnston, and Shay Smith formed TEIM Design, PLLC. Most of Triad Design Group's staff of approximately 40 engineers, technicians, and support personnel transferred to the newly formed company.  TEIM will provide all design services for Triad projects, ensuring a seamless transition. 

The name “TEIM” represents the services we specialize in:

Transportation    Environmental    Infrastructure    and    Municipal

engineering services.  Although our name is different, TEIM Design is located at the same Oklahoma City location, includes essentially the same staff previously working under Triad Design Group, and continues to provide the same high-quality engineering services to our clients.  We are excited about the future and look forward to many challenging projects!
