In college, Annette competed in cross country and track while completing her BA in pre-physical therapy. She learned firsthand the value of appropriate exercises in patient recovery for a wide variety of orthopedic and medical conditions.
Annette has worked in the clinical setting most of her career, implementing progressive exercise programs for individuals and groups. Along the way she added ACE certifications (Medical Exercise Specialist and Health Coach) and certified SAIL instructor (Stay Active and Independent for Life) to her educational toolbox.
