Onyx serves just about every small to medium sized business in our service area — the five boros of New York, as well as Long Island, Westchester and Rockland Counties. But we’ve come to specialize in these three kinds of organizations and are most familiar with their particular needs.


From small private schools to colleges & universities, educators have reached out to Onyx to connect them to their peers.

Health Care

We specialize in the highly sensitive needs of long term care and assisted living facilities. Our systems are also in doctor’s offices and health care clinics throughout the region.


Travel industry offices, hotels, and fine resorts count on communication with their clients — so they count on Onyx to get it right.
