Our People: Diedrichs and Associates

Our People


Our most important resource...

As a service organization, our people are our most important resource. They are the engineers, scientists, designers, technicians and mechanics that work with you to help resolve problems. Most have ten to thirty or more years of experience. Some are retirees that work part or full time. They have developed a wide range of products and special purpose machines and consulted on many individual problems. Product development experience ranges from concept development, to design, to prototype build and test, and production start up. Machine automation experience includes processes like small parts assembly, food processing/packaging, and special production line testing equipment.
