About Us

In 1983 EIR Testing and Maintenance began servicing OCRs for cooperatives in the Midwest area. Throughout the years, the owners of EIR and B & B Transformer worked together on many projects. Dennis Betz, of B & B Transformer, and Eric Gagne purchased EIR Testing and Maintenance in 2004 from the previous owner’s family. EIR Testing and Maintenance is located in Northfield, MN.
