Tommy Singer was a member of the Navajo Nation from Winslow, Arizona. He perfected his craft working in a small studio surrounded by his family and other tribal members. He won numerous awards and his work is published in well-known books of Indian jewelry. He learned the art of silversmithing from his father Tsinnigine Hathali, a Navajo Medicine Man. Thomas incorporates many traditional sand painting and rug designs of the Navajo people into his jewelry. He was also known for carving storyteller scenes with tremendous detail and skill. "Every piece is made with the various meanings from the traditional Navajo way of living. It was my father's dream that I learn to silversmith so that I could continue his beliefs." He died suddenly in 2014 in a motorcycle accident. His wife, Rose Singer, has continued to make his signature beaded necklaces under the new Hallmark T&R Singer.
