Sam Rommer

Excellent. Very pleased with the care I received for my back and I am looking forward to getting back into the squash court. Thank you!

Edward Hamilton

This is a very large ,pleasant space able to accommodate many people but in which there were only two patients, widely separated and wearing masks, when I attended for my appointment. Reception was provided with perspex barriers and spaces were clearly marked at two metre distances. All very reassuring. Kieran greeted me with his usual charm, and wearing mask gloves and apron. He listened carefully to my account of my complaint, examined me and explained what was wrong and what I needed to do about it. I'm confident that his recommendations will help. They always have in the past and for a variety of problems.

Ave Houston

Kieran was excellent in Initial engagement and diagnosis. His knowledge is extensive and the detail provided was clear and concise. I have found the facilities to be neat and clean, and the service to be not only accommodating, but also extremely professional. I highly recommend Flex Physiotherapy in Burgess Hill.

Marnus Marx

After one appointment I'm already feeling so much more at ease. Come away with lots of things to do and how to heal. If your thinking about it just go 🙂 kieran is really straight forward and easy to talk to!

Laura Mastrangelo

I needed physiotherapy after my back surgery and my Surgeon recommended Flex Physio. It was great to use a physiotherapy service who knew about back operations to help with any post surgery questions. Flex has provided customer service excellence with easy appointment booking, excellent physiotherapy treatment and telephone conversations to answer any questions on exercises being given. Keep up the great work Team Flex Physio and thoroughly recommended. My back feels wonderful now.

Shaun Keeling

I have been attending Flex Physiotherapy for a year with a recurrent problem and my husband has also attended with an acute problem. The physiotherapists are all extremely friendly and welcoming and have given me excellent clinical care each time I have visited. I recently attended their new clinic based at Sidney West Centre in Burgess Hill, which is a lovely facility with plenty of space for parking and a spacious waiting area. Despite covid restrictions I was able to have a safe full treatment from the team. I would highly recommend Flex Physiotherapy.

Hannah Cave

I recently started going to Flex Physiotherapy after they opened a place in Burgess Hill. I have a problem with my calf muscle after years of running which started to flare up again during lockdown. Matt has been very helpful and we even managed a face to face consultation. He is super knowledgeable, helpful and positive about my injury. I would really recommend them.

Lesley Merritt

Great Clinic with COVID safe guards. I had a running injury that was soon diagnosed. A whole load of strengthening exercises were given and advise on how to pick up my running again. Kieran gave clear concise explanations that helped me understand why the injury had occurred, why i was doing those exercises, and what tendons had been strained. Even my new trail running trainers were checked to see if they were ok for my posture. Couldn't recommend enough, this is a really good new clinic. Glad it has opened.

Matty Eeles

I have a problem with my knee and saw Kieran Barnard at at Flex. Kieran is very knowledgeable and has treated me before for a back problem, so I knew I was in good hands. He explained the exact nature of my problem (in laymans terms) and also the treatment going forward. He is very gentle and I have no hesitation in recommending him, If you are looking for a good physio, then look no further, you found him!
