Store Manager

Mike DiVirgilio

Koopman Lumber is particularly proud of Mike DiVirgilio as the Manager of our Whitinsville location because Mike first started working at Koopman as a teenager. Many in our communities have experienced KLC as their first job and many of those folks remain working for KLC today.

Mike went off to college and owned his own business for a time out of state, and then returned and managed a Koopman paint store, assisted in the startup of our Sharon location, managed a great team in Hudson before arriving back in Whitinsville where he started. From building materials, windows/doors, to paint and hardware, Mike is a great resource for any project you might have and he joins a rock solid team of experienced folks in Whitinsville who know how to serve customers.
