Established in 2018, Friends of Sierra is a non-profit organization committed to continued education through research and development to improve the science of animal physical therapy and overall health. Friends of Sierra envisions a world where service dogs are provided all modes of care needed to allow them to thrive and deliver service well beyond historical norms through physical training, quality physical therapy and injury prevention. Through continued research and education, we make physical therapy more readily available to all who need it. We envision a world where our services allow all service dogs to live a long, healthy and productive life!
