Isaac was born August 17, 1965 in Prince Rupert, British Columbia, situated along the northern coast of the province. He is a member of teh Nisga'a Nation and he takes the Frog and the Raven as his predominant family crest symbols.
In his early years, storytelling and the knowledge of his heritage was revealed to him by his elders. His father Norman Tait, a master carver, who is well versed on the traditions of his people, passed down the tradition of carving to Isaac, who embraced the craft intently. He began carving in wood and since has progressed to metals, texiles, stone, and paper. Master carvers such as Bill Reid, Joe David, Beau Dick, and Robert Davidson greatly influenced his capabilities as an artist and encouraged him to push himself to greater limits.
In 1998, Isaac moved to Santa Fe, New Mexico where he taught wood carving and flat design at the Institute of American Indian Arts. This was a program run by the Frist Nations and geared towards First Nations. Shortly after his teaching term was completed, he was involved in a one-man show at the Institute of American Art Museum was a focus on a mixed media. This was the first of its kind to take a place in the Southwest of the United States to do with a Pacific Northwest Coast First Nation's theme.

Before passing away, Isaac's experience level reflected traditional Nisga'a forms, stemming from his roots which many collectors have obtained an affinity towards.
