Shining a Light on the Future: A Conversation with James Carroll, Founder and CEO THOR PhotoMedicine

Shining a Light on the Future: A Conversation with James Carroll



This week, as part of my podcast A Week at the Clinic, (a new series from An Englishman Downunder) I had the privilege of sitting down with James Carroll, founder of THOR Photomedicine and one of the world’s leading advocates for photobiomodulation (PBM) therapy. What began as a simple interview,  evolved into a rich and spontaneous exchange that I believe many in our field—clinicians, researchers, and curious patients alike—will find illuminating.

James shared his remarkable journey, from stumbling upon laser therapy in 1986 to building THOR into a globally respected name in PBM. Our conversation explored the evolution of laser and LED technology, the development of treatment protocols, and the ongoing challenge of navigating regulatory pathways that often lag behind scientific innovation.

A key theme that emerged was the disparity between academic interest in PBM and its uptake in clinical settings. While universities continue to publish promising data, mainstream medical practice remains hesitant. We touched on reasons for this lag, including the slow process of regulatory approval and the uphill battle for treatments to be included in care guidelines and reimbursement frameworks.

James spoke candidly about the bureaucratic obstacles facing off-label applications, and the risks posed by inferior devices flooding the consumer market. He also highlighted significant international breakthroughs—such as Lumithera’s FDA approval for PBM in the treatment of  macular degeneration disease—and spoke about his upcoming research, including a PhD focused on improving PBM dose accuracy.

On a practical note, we discussed patient success stories, particularly in dental and musculoskeletal applications, and the promising expansion of THOR’s Protocol Library to better support front-line practitioners like myself.

The full episode will be released this Sunday. I hope it offers insight into not only where photobiomodulation has come from, but where it is so clearly heading.

Until then,

Kevin

There are moments when even angels weep. This is an article I wrote for another publication and have permission to reproduce here. I write as: * The CofE House of Bishops change direction on services of blessings on Same Sex couples and their acceptance of SS clergy who have entered into a civil marriage contract. * The  Anglican Diocese  of Ballarat in Synod at the  Anglican Cathedral Church of Christ the King - Ballarat  receive and debate a motion in relation to the place of GBLT in the local church. Moments when wings feel too heavy, when the light they carry dims beneath the weight of sorrow or silence. In those moments, another angel comes — not to preach, not to fix, but simply to be. To sit beside, to listen, to hold the space sacred and still. Too long have many of our brothers, sisters, and siblings been told that heaven has no room for them — that their love, their truth, their song is somehow “less.” But I say this: the divine is found wherever love abide...

Anchored in Justice, Called to Hope

This Sunday’s readings for mass/holy communion from the Revised Common Lectionary are anything but comfortable. I have already written about them but I find myself going back and re-engaging with them I have also written a hymn that can be sung to the tune Tallis’ Canon (443 in togeather in song). Amos thunders against those who lie at ease while the poor go unnoticed at their gates. The psalmist reminds us that God raises up the lowly and calls His people to justice. Paul urges Timothy to fight the good fight of faith with perseverance. And then comes the parable: a rich man feasting, blind to the misery of Lazarus lying right outside his door. It is a hard mirror to look into. These passages don’t allow us to hide behind a purely private faith. They make it plain: to follow Christ is to notice the neighbour at the gate, to let compassion disturb our ease, and to act. And yet, despite their sharpness, there’s something hopeful in them too. The scriptures never expose our fa...

Beyond the Fluff and the Fur

🕊️  The Feast of Saint Francis: Beyond the Fluff and the Fur Every year on October 4th, the Feast of Saint Francis of Assisi comes around with wagging tails and flapping wings. Churches fill with Labradors and lorikeets, poodles and parrots, all queued up for their annual blessing. It’s a delightful sight — a moment when even the most hardened church-shy neighbour will wander in, dog leash in hand, for a photo-worthy moment with the local vicar. And yes, The Vicar of Dibley captured it perfectly: chaos and holiness mingled in equal measure — goats bleating, cats hissing, and Geraldine Granger standing there with that divine mix of amusement and exasperation. It’s a scene that could happen in any parish hall, really. But beneath the comedy lies a deeper question: have we turned the blessing of animals into a feel-good marketing event — or are we genuinely hearing the call of Saint Francis to honour creation itself? Saint Francis: The Radical, Not the Romantic Saint Francis wasn’t ...
