I have taken several classes in sand casting with Brienna and they are always excellent. Brienna is a wonderful instructor--knowledgeable and patient. She helps each student throughout however many projects they want to do. Her advice at the beginning on how metal will behave in any given design is invaluable and her insight on when something doesn't work is equally so. Brienna's enthusiasm is infectious and makes her classes a joy to take. I highly recommend Brienna's classes and plan to take as many as I can.
