Armstrong Machine Company, Inc. was started in 1974 in Armstrong, Iowa, by Clifford and Sharon Porter. Cliff was in the Well Drilling and Pump Repairs service, Sharon was the High School Principal Secretary and also did the book work for the Well Drilling Business. The company was started with one employee, who shipped the parts from a little shed near the Porter's home. The company was moved to Pocahontas, Iowa in 1977 when Cliff sold his Well Drilling business in Armstrong because of health problems and the family relocated to Pocahontas, Iowa. The company was then run out of the Porter's home and their small garage acted as their machine shop. Very soon a building was put up to house the company and the first manual lathe was purchased. In 1988 an additional building was put up to house the growing company but within a few years the company had out grown this facility as well. Cliff ended up purchasing property adjacent to the existing property and built another building where the mud pump repair department and the steel tubing were then to be stored. In 2002 a building was put up to house the new heat-treating facility.

The company is now run by Clifford Porter and his daughters, Michelle Ames and Roberta Reese and employs over 30 people. Currently, we have customers in each of the 50 United States as well as 49 foreign countries.It is our hope that we can continue to grow and serve our customers.
