About e3 Diagnostics New England
e3 Diagnostics New England was established as the direct factory representative for Grason-Stadler (GSI) products in New England in the 1980s. We originally were located in the same building as manufacturing which was based in Littleton, Massachusetts. When space became an issue in the late 1980s, we acquired our own office at 531 King Street. Although we were a part of GSI, we operated as an independent sales and service office for the New England states.
