Onyx brings the fresh, urban feel of downtown Phoenix to the historical district's expanding art scene.

Kat Williams


The Williams are a pair of art enthusiasts and collectors.  They are Chicago natives who relocated to the valley of Phoenix in 2016, bringing with them a new blend of urban sophistication and innovative vibes to the historical district's Grand Avenue galleries and spaces.  Onyx Gallery is succeeding in its quest to bring artists, patrons of the arts and collectors together via its series of exhibits that have been smartly presented and well-appreciated by the community.
