Callan started ballet training on Guam with John Grensback and Megan Murphy. After apprenticing with Carolina Ballet under the leadership of Robert "Ricky" Weiss, she walked away from dance, to return 18 years later as an adult student. Callan’s yoga barre classes emphasize individual expression, constant creativity, and innovation. Her technique is greatly influenced by her training at the Laughing Lotus in New York City. Breath-work and ease of flow are two hallmarks of this practice, while at the same time being mindful of each person’s alignment, structure, and comfort level. She offers alternative postures and encourages listening to the changing needs of your body, while emphasizing that yoga barre should be fun and accessible.
