Thea has been a stone mason since 1986 and sculptor since 1998. First apprenticing seven years under master masons, then branching out to study stonework internationally in England, Canada, Italy, China and Mexico. She settled comfortably into a unique style and perspective of stone work, design, installation and team leadership.

Alvin has been teaching with Yestermorrow since 2008. She enjoys teaching The Art of Stone and Masonry Oven Programs annually and also Historic Restoration in Italy.

Alvin specializes in arch construction and large scale sculptural installations at Universities and Galleries across the US. Internationally, Alvin specialized in stone building and roof systems.

More recently, Alvin 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 3500 hours working, to shape new perspective on color theory that stone alone could not give.

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