Matt’s background is in banking and finance, but in a bit of a career change he joined Knebworth Physiotherapy Clinic as Practice Manager 15 years ago. During his time here he has overseen two premises moves whilst the Bragbury End redevelopment was ongoing, and was part of the team that designed the fabulous new clinic.
In his spare time, Matt has been on the committee at Stevenage Cricket and Hockey Sports Club for 20 years, including a lengthy stint as treasurer and, along with his wife, spends evenings and weekends ferrying their young son around to football training and matches for his two grassroots football teams.
Matt also enjoys music and attends gigs and festivals as much as possible, although it is some years now since he last went to Glastonbury!

Gloudien Olivier
Chartered Physiotherapist
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. Aside from her hands on treatment, Gloudien feels getting to the root of the problem and giving sound advice is an equally important aspect of the treatment so that the patient and the physiotherapist can work together to alleviate symptoms.
Gloudien’s family have been very involved in Athletics over the years. Her daughter competed at a National level in high jump over the last 7 years. Her husband Philip is also an Athletics jumps coach in his spare time. Gloudien has in depth understanding of supporting athletes with injuries.

Jocelyn qualified from St George’s in London in 2007. She initially worked privately in both a physio- rehab and Pilates role. Qualifications in both mat and equipment Pilates gave her the opportunity to work with patients from post injury to higher level strength training. She later joined the NHS and trained further in acupuncture. She worked closely with the newly developed chronic pain unit, helping patients understand why they have pain and how to get moving again after long periods of pain-limited activity, using techniques such as CBT and exercise therapy. Alongside this she developed her interests in women’s health and pregnancy-related musculoskeletal issues. Her interests also include sports rehab, using gait analyses to understand why some patients get persistent running-related injuries, but she also has a love of horse riding, tennis and rowing and their related injuries!
