I contacted Northstar on behalf of our company. We were stunned with the immediate, outstanding service we received when we were not an existing customer. We needed a technician to determine a problem on an existing alarm system. Grant came out a few hours later, corrected the issue, offered suggestions for improvement and answered a myriad of questions we had. We are so delighted to work with Northstar Security, Inc. and anticipate adding new equipment because of their attention to detail! Thank you! 
Barbara did a superb job of connecting us to the right person!
