The Oregon Ballet Academy is dedicated to offering the finest in dance training and performance. As a self-sustaining community arts organization, we provide a training ground for talented, aspiring artists and dance enthusiasts of all ages. We hope to inspire the love of dance and appreciation of music in students of varying abilities and ages, from preschool to pre-professional. We support the growth of classical ballet by maintaining the highest standards and by nurturing the talent of every student.

Pre-professional students have the opportunity to develop the skills, experience, and discipline which are the necessary foundations for a professional dance career. Our director is an accomplished professional dancer who brings his experience to bear for the benefit of our serious students.

Those students whose paths lead to non-dance careers gain immeasurably from having studied at OBA. They develop self-motivation, self-discipline, poise, grace, and an appreciation for the arts which they will carry with them throughout their lives.
