Remember Hurricane Sandy? We do. We remember
millions of New York and New Jersey residents,
businesses, hotels, hospitals and public service
departments losing power and phone lines making it
impossible to communicate. That was the beginning of
GrayMatter Networks – We were spawned as an
emergency response team to get the east coast
telecommunications back online. Since that 2012 disaster,
we’ve expanded our VoIP solutions, but deep down we’re
still that same driven information technology team that
saves the day when the day needs saving.
