Nexus Health Tools creates precision instruments for the muscles traditional tools can't reach — because our founder was the first patient.
Bryan Lee knows what it feels like to lose your life to pain. Not just the physical part — the weekends with his wife that turned into him lying on his back, unable to move. The marriage strain. The daily life that shrank down to what he could manage from a mattress.
He went through the usual rounds: doctors, spinal injections, heavy-duty medications. Nothing worked. And the one thing every specialist eventually suggested — surgery — he refused. Too many stories of surgeries not helping or making things worse. He wasn't willing to take that gamble.
So he started doing his own research. He tried every psoas and iliacus release tool he could find. Some helped — partially. But none delivered the deep, targeted release he needed, and he had to juggle two or three different devices just to get any meaningful relief.
But as an inventor at heart with a background in mechanical engineering and 3D design, Bryan couldn't accept defeat.
He spent over a year and a half designing, prototyping, testing, and refining — dozens of iterations, each getting closer to what a skilled physical therapist could do with their hands. The result was the Core Nexus: a psoas and iliacus release tool that combines the functions of multiple devices into one compact, effective, time-saving solution.
Using the Core Nexus consistently was the turning point. Bryan started enjoying weekends again — actually doing things instead of watching from the couch. He got back to living with fulfillment.
He knew that if this tool could help him climb out of nearly a year in bed, it could help other people going through the same struggle — people who'd been told their only option was surgery, people who just needed a way to target the right muscles and couldn't find the right tool.
That's why Core Nexus exists. Not because Bryan wanted to start a business — because he needed this tool to exist, and once it did, keeping it to himself felt wrong.
