At the age of 14 Greg began making pottery under the eyes of Severa Tafoya, his maternal grandmother. She taught him all the fundamentals of the traditional Santa Clara way of making pottery. She also encouraged him to stay within the long family tradition of working with clay.
Greg specialized in the hand coiled traditional black and red Santa Clara pottery. He did everything the traditional way, praying at every step. He also polished his pottery to add a great shine to his pieces.
Greg signed his pottery as: "Greg Garcia, San Juan/Santa Clara". He passed on in 2010.
