The 27,500 square foot corporate office and manufacturing facility is located in Kennewick, Washington in the heart of Columbia River Basin agriculture. The Dammer Diker®, which was developed and patented by company President, Thayne B. Wiser, is manufactured and distributed worldwide by AG Engineering.
