Introducing our online MSK Education Series

By Greg Fritz, PT, DPT, RMSK

Clarius is partnering with MSK ultrasound Imaging pioneer Greg Fritz, PT, DPT, RMSK, to deliver online presentations to help clinicians update and refine MSK imaging skills.


Greg was one of three physical therapist recipients in the nation who earned a Pioneer Certificate in Musculoskeletal Ultrasound Imaging (RMSK) in Washington State. He believes ultrasound imaging is pivotal in the correct management and diagnosis of many orthopedic injuries. Greg regularly lectures at the University of Washington and trains other interested clinicians in the use of musculoskeletal ultrasound (MSKUS) in their practices. He is on the faculty of a distinguished Regenerative Medicine/Orthobiologics innovator (Don Buford, MD).
