Karpp – A New Identity with a Renewed Commitment

Continuing excellence for New England construction customers

In 1979 Robert N. Karpp, founded an independent, family-oriented business offering quality building supplies to customers in Massachusetts. Plenty has changed since then – like the Robert N. Karpp Company becoming part of the industry-leading GMS family of companies. One thing that never has and never will change, is our dedication to customer service.

In this spirit, we are pleased to announce that Robert N. Karpp has evolved our corporate brand and logo. Following a process that began a few years ago, and which involved careful consideration, we are officially beginning our transition to being known simply as “Karpp”.

Under the banner of this new name, Karpp will still operate with the same integrity and commitment to customer service. We are proud of our history, but equally excited for our future as we continue to grow as the preferred building material distributor in the market.
