Darlene Macatangay, Instructor

Darlene is in the midst of obtaining her Doctor of Physical Therapy degree at Pacific University. After working with high school athletes and individuals with neurological injuries, she found that nothing is more rewarding than helping someone find the power to overcome their personal challenges. A few other things she enjoys doing are exploring the outdoors, dancing, and rock climbing. In November 2018, she volunteered at Spectra's Thanksgiving Day Camp and was immediately drawn to its uplifting atmosphere and positive community. She is excited to continue fostering this culture with everyone at Spectra!


Brian Thomas, Instructor

Brian is an Oregon native who used to live and breathe gymnastics, competing for ten years, coaching all ages and levels for another six years, and judging competitions. He has spent the last fifteen years developing a career in the tech industry, but has never lost his love of gymnastics or teaching. During a two year stint teaching English in Japan, Brian got the chance to work with middle school special needs students, and was hooked by their spirit and enthusiasm, and willingness to exchange cultures. Apart from work, Brian loves table tennis, book clubs, and Japanese tea ceremony, but will always be a gymnast at heart. Brian feels that gymnastics is a fun and wonderful way to foster growth and confidence in children.
