Douglas Rosario, PT, MHA

He received his physical therapy training at Loma Linda University and his Master’s degree from California State University in health administration with an emphasis in health education.

He has performed clinics, basketball camps, training programs for high schools, little league and soccer throughout the greater Portland area.

Doug has had the good fortune of expert mentorship by both top tier physical therapists and orthopedists from across the country. This has been coupled with his experience of having worked with thousands of post-surgical patients with special expertise in the knee, ankle, shoulder, and elbow. He utilizes “evidenced based” practice, not because they are the “buzz” words of today, but because it has always been the right thing to do. Doug’s focus is he wants you to be an expert and champion in your own care. He will help you navigate, by giving education and tools to reach your goals. Doug would be honored to treat you or a loved one.

Doug loves being with his family, enjoys telling/hearing stories, being outdoors, working with his horse, playing golf and has a never ending love for anything related to baseball. Doug would love to have you share your story with him.
