Daniel Marsh is 54 years old. He lives in Sale, just south of Manchester. He spent 26 years calibrating and maintaining the clinical devices used in NHS hospitals and private facilities alike.

In April 2023, his lower back gave way. Not gradually. All at once.

'I couldn't reach my feet to put my socks on without a lightning bolt through my lower back. My daughter's wedding was fourteen weeks away. I thought: I am not watching that from the car park.'

He did not go private. He could not wait for the NHS. He went to his workshop.

"The first prototype had LEDs taped to neoprene. My wife thought I'd lost the plot. It looked like a prop from a low-budget science fiction film. But it worked. And that was all that mattered."

The morning after his first week of sessions,
Daniel woke up in his house in Sale. He walked to the kitchen. He made tea. He stood at the window.

He wrote one line in his notebook:
'Normal morning.'

He hadn't written that in fourteen months.

Now, that same engineering is helping thousands of people bypass NHS waiting lists — manufactured to the same clinical-grade standards Daniel spent 26 years maintaining in NHS hospitals and private facilities.
