Online Diamond Plates’ roots can be traced back to 2013 and a small suburban garage in Golden, Colorado.

What began as a side business to help fund my soon to be born son’s education, quickly outgrew the garage.   Although Online Diamond Plate has grown considerably since its humble beginnings, we hold strong to the values that got us here and remain a small family owned business located in Golden, Colorado.
