Our Solutions


Leva Clinic (CQC registered) is the first fully online clinic for patients with chronic pain. Our multi-disciplinary clinical team comprises of expert clinicians, clinical psychologists, physiotherapists and nurse consultants.  The team support patients through personalised online care plans. 


Cellen Therapeutics aims to improve research and innovation into therapeutics for patients with chronic pain. Alongside leading academic institutions, we have begun with cannabinoid medications and developed digital tools to support clinicians in understanding current best practice through our MedCan Hub. 

“Back pain is the single largest cause of disability in the UK, with an estimated 3 million people out of the labour force as a result of chronic back pain. As a science-led company, Cellen is proud to be finding innovative solutions for people living with chronic pain."
