Our aim is to help you to achieve your goals and empower lifestyle change, whether you are a professional athlete or a casual gym goer. 

The Performance Clinic was established in 2014 with the ambition of providing elite level physiotherapy and fitness services to the North Kildare area. Mark Kenneally heads up the physiotherapy clinic and Albert Nagel runs Peak Performance Fitness.

The physiotherapy clinic focuses on providing the highest standard of care possible to help you recover from injury, become pain free and understand how to manage your problems on an ongoing basis. We have built a strong reputation for specialised physiotherapy in Celbridge and North Kildare; patient centred, evidence based and effective intervention for pain and movement dysfunction.  All of the treatments we offer are in line with the latest best evidence-based research. We believe in working with patients in a holistic approach to recovery, educating you, the patient, on the exercises and techniques that will allow you to actively participate in your own recovery and future physical health.  

Peak Performance Fitness is headed up by Strength and Conditioning specialist Albert Nagel. This is a state-of-the-art gym facility, where members get the maximum benefit from small group personal training.   
The clinic prides itself on using both physiotherapy and Strength and Conditioning approaches to help you not only overcome injury but to avoid injury in the future. 

At The Performance Clinic we provide a full range of expert Physiotherapy & Fitness services.
