Kinetic activity leads to heightened focusing abilities and increased motor skills, while the creative aspect encourages self-expression and communication.  The complete dance experience fosters risk-taking, increases self-awareness and enhances interpersonal skills.  <br/><br /> <b>Our classes</b> provide a unique mixture of dance traditions and forms.  Each class begins with a warm-up that incorporates elements of classical ballet, modern and jazz dance techniques.  Students are familiarized with dance vocabulary, proper alignment, and other important principals of technique.  Additionally, they stretch and strengthen their bodies, build stamina, and increase their overall physical health.<br/><br/>";
