10/10

John Hamwi was very professional, courteous, personable and efficient. I called and they arrived in a very timely manner. Good customer service to difficult to find these days but 100% with ONC! When I replace my garage door I will go back to ONC. Thanks ONC!

Melinda went above and beyond with her customer service. Her follow up was great, she made sure all my needs were taken care of. Her customer service could not of been any better. She is the reason I stayed with Grand Alarms.
