A researcher/author like his father, Mark has written a number of books as well, including A Consumer's Guide to Southwest Indian Art, Pueblo Stories and Storytellers, Navajo Sandpainting Art (co-authored with Eugene Baatsoslanii Joe), Collecting Southwest Native American Jewelry, Southwest Indian Weaving, Southwest Indian Designs, Spirit in the Stone (a book on animal carvings and fetishes) and, most recently, Silver and Stone, profiling dozens of silversmiths. He is also working on a book on the history of Southwest Indian jewelry and a couple research projects, having just revised and expanded Spirit in the Stone.
And, like his father before him, he continues to be involved with Indian-run organizations addressing education, health and employment issues. He is a long-time board member of the Tucson Indian Center, serves on the Institute of American Indian Arts' Foundation Board in Santa Fe and on the board of directors for the Amerind Foundation in Arizona for nearly a decade as well as a former board member of the Southwest Association on Indian Arts.
2024 marks his 52nd year doing what he loves.
