Crystal DeMarco, PTA

Crystal grew up in Keno, Oregon. She moved to Redding and graduated from Enterprise High School. Crystal started a family while working in elderly care and also as a NASM certified personal trainer. In addition, she did bookkeeping for the landscaping business she owned with her children’s father. Crystal wanted to make a bigger difference in the world and to start a career using her elderly caregiving and personal training skills. This led her to join the first cohort of the PTA program at Shasta College. During Crystal’s time in the PTA program, she completed outpatient, skilled nursing, and aquatic therapy clinical rotations. Her primary focus and goal with her patients is to enhance longevity and quality of life through improvement of body mechanics and functional abilities while decreasing pain. In her spare time, she enjoys shooting, off roading, kayaking, singing, painting and, most of all, quality time with her 3 kids.
