Ahern recently held a series of events for Women in Construction Week. One of the events included our first-ever Women’s Build Event. During this virtual event, Ahern employees and their daughters assembled an Ahern branded aesthetic jewelry stand. The event kicked off with an introduction from one of our executive vice presidents, as she presented keynote speaker and instructor for the evening, one of our fire protection design managers. In continuing Ahern’s motto of “safety is the most important thing we do,” one of our safety business partners spoke about the importance of safety, and she ran through some tips and tricks on how to ensure we worked safely during the event. Our design manager went on to walk participants through the step-by-step process of building the jewelry stand while she showed them how to following a set of plans drawn by our very own design team. While not everyone was able to attend the live zoom call, in total, we had 36 Ahern employees and 47 young ladies participate in the event.

    I applied through a recruiter. I interviewed at J. F. Ahern (Plymouth, MN) in Nov 2021


    First was a Phone call with the design manager and the general manager. Then there was a zoom call later in the week. Then finally an in person interview. Everything was relaxed and friendly.

    They had me describe some of my previous work and what issues I ran into and how I overcame them.
