Gloudien OlivierGloudien 2016

Gloudien qualified as a physiotherapist in 1999. She has had an interest in the physiotherapy management of musculoskeletal injuries since she started working. Over the years she has worked closely with orthopaedic consultants, providing physiotherapy treatment and advice to enhance patient recovery.

Gloudien moved from South Africa to the UK in 2002 and worked at the QE2 hospital in Welwyn as a senior physiotherapist in the out-patient department. Since 2005 Gloudien has been working in private physiotherapy practice. Here she has gained valuable experience in treating sports injuries and musculoskeletal conditions.

She has a special interest in treating back problems and sport injuries and finds her medical acupuncture a great asset.
