Twinbrook School of Ballet is an excellent school. My daughter has taken classes there for 7 years now and I just started a beginner adult class myself. The curriculum is Royal Academy of Dance and is rigorous, but is taught in a nurturing environment. It's a small school so every student receives personal attention and instruction. They offer classes for all ages 4 years up to adults. Phyllis Blake is the school's director, and her talent and love for teaching is evident in every class.
