On behalf of DCU, I am very happy with the customer service provided by Nashoba Security. They are a great asset to DCU providing professional and knowledgeable services including installation and hardware repairs for our Main Office locations and network of branch locations in Massachusetts and NH; including responding to any emergency calls in an extremely timely fashion. We could not be more satisfied with Nashoba Security and any organization would greatly benefit from the services that they provide. We look forward to a continued partnership with them.

I would like to take this opportunity to thank you for your timely response and assistance at…. on Tuesday, January 21, 2014. Your time and efforts significantly reduced the potential damage to the residence as well as helped save a life! Your actions aiding in the assistance of the patients removal were above and beyond the call for your assistance. It is nice to know there are members of our community that are still waiting to help at a moment’s notice. Again, I thank you.
