The collection consists primarily of low relief constructed sculptures that are framed for a distinct presentation. Diaz utilizes three different metals: recycled aluminum (from cans), aluminum, and stainless steel. All metal materials are of a thin gauge, which are cut and then sculpted into forms using a technique developed exclusively by E. Moises. All pieces are crafted meticulously by hand; no machines or presses are used.

Diaz is a self-taught artist. He received his degree in Sociology, from Chapman University, located in Orange County, CA. Diaz and his family currently reside in Austin, Texas.
