Thea Alvin has been a stone mason since 1986 and a sculptor since 1998, first apprenticing seven years under master masons and then branching out to study stonework internationally in England, Canada, Italy, China, and Mexico. Alvin settled comfortably into a unique style and perspective of stone work, design, installation, and team leadership. She has been teaching with Yestermorrow Design/Build School since 2008. She enjoys teaching The Art of Stone and Masonry Oven Programs annually, as well as Historic Restoration in Italy.

Alvin specializes in arch construction and large scale sculptural installations at universities and galleries across the US. Internationally, Alvin specializes in stone building and roof systems. More recently, she has taken a deep dive into stained glass, initially taking a course at Yestermorrow, which was quickly followed by setting up a home studio. She now has more than four thousand hours working to shape new perspective on color theory that stone alone could not give.

Alvin lives on her 1810 restored farm in Northern Vermont with two dogs, nine goats, seven fish, and thirty-something chickens. The farm has seen countless courses and workshops to complete the restoration process and is now a sculpture park, open by appointment.
