Born circa 1950-2017, Tsinnie began producing jewelry circa 1970. Often he collaborated with his wife, Darlene Tsinnie, which is why his stamp often incorporates both their initials.
Tsinnie won many awards at Indian Market in Santa Fe from 1976 forward. His work was routinely sold through Shush Yaz Trading Post in Santa Fe and in Gallup and at Toh-Atin in Durango, Colorado.
