James Atter

Chartered Physiotherapist and Advanced Practitioner

I’m a Chartered Physiotherapist and Advanced Practitioner with a passion for helping people move better, feel better, and live well.

Over the years, I’ve worked across the NHS, elite sports, and private practice, combining hands-on expertise with a genuine commitment to patient care. I now work as a first contact practitioner alongside general practitioners and spend the rest of my time focusing on private practice.

My approach blends advanced skills in assessment, rehabilitation, joint and soft tissue injections, acupuncture, and electrotherapy — but what truly drives me is building real connections and tailoring treatment to each individual.

I have had advanced training in jaw pain (TMD) assessment and management. I am an experienced independent prescriber and provide joint and soft tissue injection consultations. I also have experience in providing shockwave therapy, low power laser therapy and cryotherapy. I am currently completing my sports and exercise physiotherapy master’s degree with a particular interest in force plate assessment.

Let us support you towards better health and wellbeing.

Back pain

November 3, 2026

I’d honestly like to thank Gin at Physio at one. I was suffering badly with lower back pain (Glutes). I could hardly move on Monday without being in pain. After a session with her I’m feeling much better able to move and hopefully on the road to recovery following the exercises she’s given me. Thank you so much

Excellent experience and highly recommended!

October 30, 2026

I attended Physio at One following a period of struggling with hip and lower back pain. Gin carried out a thorough assessment in a kind and professional manner, taking time to fully understand my concerns. I felt very reassured by Gin’s excellent clinical knowledge and friendly approach. Following the assessment, Gin gave a clear explanation of the likely cause of my pain and provided a clear plan of action. Overall an excellent experience and would highly recommend Physio at One!

Shoulder injury while on holiday in the UK

I fell down stairs and badly hurt my neck and shoulder. I saw Gin, who took time to assess and understand my injury before providing some great relief. Really great service.

Mummy MOT was fantastic!

Had a Mummy MOT appointment with Rhian yesterday and it was great. Rhian was friendly, knowledgable and empathetic. The assessment was very thorough and left me feeling reassured and confident to get back to training safely. Thank you!

Magic hands

Booked on the off chance with Ben and I am so glad I did. He is absolutely amazing, he knew exactly what was wrong with my back and gave me plenty of exercises to do at home. His massages are so relaxing. Wouldn’t hesitate to recommend him

Highly recommend PhysioAtOne, following  a long-standing injury Gin got to the root of the problem and provided a  rehab programme and treatment that worked for me, now feeling 100% times better, fully fit and back to my training routine. Thanks Gin!

 Trustindex verifies that the original source of the review is Google. Gin made me feel very comfortable and talked through the issue in depth. Following some magic thumb manipulation the pain is gone with just one treatment. It’s wizardry in my eyes and I can get on with life as normal again. 1st class professionalism for such a modest cost and better than waiting six months in pain for an NHS appt. Would definitely recommend to anyone as a 10 out of 10.

 Trustindex verifies that the original source of the review is Google. Excellent and friendly physio treatment from Gin at PhysioAtOne. I got a very quick response to my initial enquiry and a first appointment to deal with a knee injury within just a few days. The first appointment was a detailed assessment with clear explanations of what was wrong and demonstrated exercises of how it might be put right. By the end of that day I had a personalized treatment plan and app emailed to me. Two weeks later, at the follow up session, the results are speaking for themselves with increased flexibility and strength. I would and will recommend her to others.

 Trustindex verifies that the original source of the review is Google. During the start of the summer tennis season, I picked up a shoulder problem which really effected my serving. It got to the point where I couldn’t serve without a lot of pain so I went to see Gin. After a session with Gin, she worked out the issue and gave me a lot of exercises to do in the mean time. Since then, I have not had any issue at all with my shoulder and am playing completely pain free.
