Hannah Patchen, Instructor

Hannah is currently a student of physical therapy at Pacific University with a special interest in the pediatric population. She has always been interested in exploration, growth, and expression through movement, as is demonstrated by her long history of practicing both gymnastics and dance. She thinks Spectra is the perfect place to mix learning and play, and is excited to combine her personal experience with specific strategies to benefit each child individually. One of her favorite parts of this work, however, is watching the personality and creativity that each gymnast brings to class!
