What Makes our Training Site the finest in the Country?

The Joseph J. Goetz training site in Coloma consists of nearly 400 acres of rolling Kettle Moraine hills and services every member from the beginning apprentice to the accomplished journey worker looking to either diversify themselves in our trade, or to hone the skills they have already acquired in the field. In-seat training is conducted with current, late model equipment acquired through the equipment loan program. Certifications are also available through our training programs.

What makes our training site one of the finest in the country? A great staff, participation of concerned contractors & equipment dealers, and the ideal location of the site itself are a few of our strengths, but the strongest ingredient is the strong support of our membership. Active members of Local 139 allocate money from their negotiated pay-raise to fund this program & assure state of the art training is available for apprenticeship & journeyman training. The dividends on their investment? A well trained, safe and proficient workforce that strive towards better working conditions with great economic packages!
