About Robert Mast
Robert Mast is a specialist Advanced Practice Physiotherapist (APP) with more than 30 years of experience in managing complex musculoskeletal conditions. He holds a BSc in Physiotherapy from the Hogeschool van Amsterdam (HvA), a Postgraduate Certificate in Musculoskeletal Sonography from Canterbury Christ Church University, and independent prescriber rights gained through London South Bank University. He is registered with the HCPC and is a member of the Chartered Society of Physiotherapy (MCSP).
Rob trained and qualified as a physiotherapist in Amsterdam in 1993. From the outset, his clinical focus was musculoskeletal practice — the assessment, diagnosis and treatment of the full range of MSK conditions from acute soft tissue injuries to complex chronic presentations. He moved to the United Kingdom and has been working as an Extended Scope Physiotherapist in NHS primary care since 2004, where he holds an expert clinician post providing both clinical diagnosis and point-of-care diagnostic and interventional musculoskeletal ultrasound.
Rob began using diagnostic ultrasound in 2008, recognising early on that imaging-guided assessment and injection therapy would significantly improve diagnostic accuracy and procedural safety. He obtained his Postgraduate Certificate in Musculoskeletal Sonography in 2010 — making him one of a small number of physiotherapists in the UK to hold a formal postgraduate qualification in MSK ultrasound. Since then, he has performed thousands of ultrasound-guided procedures, including cortisone injections, hyaluronic acid injections, joint aspirations and barbotage.
At Sonoworld, Rob combines clinical physiotherapy assessment with real-time diagnostic ultrasound and, where appropriate, immediate interventional treatment through our ultrasound-guided injection clinic. His commitment to education is a defining feature of his career: he is a core faculty member at The Ultrasound Site, an honorary senior lecturer at Brunel University, and a visiting lecturer at Canterbury Christ Church University.
