Terry's primary crest symbol is Sílhqey (double headed serpent). He carries the ancestral name of Siyemches, a name passed down to him by his grandfather, Frank Malloway. His education took place while working under the direction of his father, Francis Horne, and uncle, Doug Lafortune. His brother is well-known carver Francis Horne Jr. Terry assisted his uncle in the completion of two 30-foot totem poles for Butchart Gardens' 100th Anniversary in Victoria. In 2019, Terry was commissioned to create a large Stó:lō house post for the Chilliwack YMCA. Many of his sculptures and masks contain unique features involving shamanistic elements and atypical formline design.
