Our History

As a primary innovator in the technological advancement of the vehicle emissions testing industry, Gordon-Darby has pioneered many new techniques and processes that have subsequently become standard in today’s Inspection & Maintenance (I/M) programs. In collaboration with the U.S. Environmental Protection Agency (USEPA), we have continually strived to improve the I/M industry with the ultimate goal in mind: cleaning up the air we breathe.

The pursuit of this goal has led our company to achieve many industry “firsts” that have become standard practices in I/M programs throughout the United States. Brief summaries of Gordon-Darby’s major accomplishments are listed below.
