In this extended episode of A Week at the Clinic, host Kevin Harper dives into the evolving world of Photobiomodulation with James Carroll, an internationally respected leader and global pioneer in the field.
Kevin Harper explores how a once-niche therapy is becoming mainstream, and why we are embracing the term photobiomodulation to reflect its future.

Together, they explore the evolution of PBM, its clinical applications, and the science that underpins this emerging modality. James shares reflections from his decades of work in the field, including the transition from early-stage therapeutic lasers to today’s precision-driven, evidence-based protocols.

Whether you’re a patient curious about how PBM works, a clinician seeking clarity, or a researcher chasing rigour, there’s something in here for you.

This is an interview featuring me by Dr. Ben Sinclair, a British physician /  general practitioner (GP) Sinclair. His podcast is called Health Versus Wealth. Primarily, this podcast is about my health choices and routines. He describes me as a “highly driven entrepreneur, 61 years old (now 62), of  THOR Laser company (correction: THOR Photomedicine Ltd and THOR Photomedicine Inc), of which he is is Founder CEO, which specialises in design and manufacture of Photobiomodulation (PBM) devices. THOR £10 million a year in sales, has 5,000 customers in 70 countries, and is marking THOR’s 30th anniversary.” Dr Ben says I am “a businessman who prioritises his wealth, in that he works 364 days a year! (actually, my motivation is establishing PBM as a first-line medical treatment in every department of every hospital in the whole world), wealth might be an outcome, but it is not the goal.) How does this impact his work-life balance? “The only day I take off is Christmas Day,” he says. Despite this, he says he’s in fine health, fit and eats a nutritious diet.

THOR’s celebrity clients include Mo Farah (Mo only used NovoTHOR whilst training with the Nike, Oregon project), Novak Djokovic, Hollywood actor Mark Wahlberg, and his biggest-name customer, film star Tom Cruise. Cruise famously broke his ankle during filming in London on ‘Mission Impossible: Fallout’ in 2017 while leaping from one building to another. Cruise used James’s laser to recover, and now he has lasers in his homes and is always one on location. James LED a workshop in Florida, and Cruise walked in wearing his trademark aviator sunglasses. “Tom was a delight,” says James. As for his business ambitions to grow the company, James adds: “My real goal is to get this technology into every corner of every department of every hospital in the whole world.”
