National Lumber hosts classes in our second floor Training Room at 245 Oakland St, Mansfield, MA. (Map and Directions) Please park on the side of the building or on the side street, not in the parking area near the front entrance that is for customers.

As in our stores, fully vaccinated customers and employees are not required to wear a mask inside. Anyone not vaccinated is requested to wear a mask inside and maintain 6 foot distancing from others.

Outside training companies have been offering classes elsewhere or offering online learning. As they book upcoming classes in our Mansfield Training Room, they will be highlighted here. Scroll down to see the section for each training company.
