" All the work we put into our careers, the biggest problem is it never reaches the people who need to hear it. Onix is going to demonstrate that AI can scale that knowledge and help heal the world. "

Dave Rabin, MD

Your Nervous System Is Trainable

" Medicine spent the 20th century learning how to fight disease. The 21st century is about learning how to create health. That shift requires personalizing everything, from nutrition to environment to how we think about the immune system. Onix gives me the platform to bring that vision directly to the people who need it most. "

Jeffrey Bland, PhD

The Father of Functional Medicine

" It's an honor to be part of Onix, a truly unique service platform. CEO David S. Bennahum has built this with the highest standards of quality and integrity. "

Elissa Epel, PhD

Redefining How We Age

" Everything I've built has been about helping people find what actually works for their biology. Onix gives me a way to do that one person at a time, at scale. "

" If I see one person in my office, that's one person. But over decades of books and videos, we accrue all this information, and it's so hard, in a single visit, to deliver it all. If you're in Cleveland, how am I going to get to you? This is such an empowering way to distill it and give it to people. I'm really excited to see where this goes. "

Jordan Metzl, MD

Unlock the Science of Fitness

" I saw Onix as a path forward to reaching women, because the future of medicine really is AI. It's continuous, it's invisible, it's frictionless, and most importantly, it's at home, there to answer the questions when we can't be. "

Krista Ramonas, MD

Female Longevity

" I've watched too many patients end up in my unit for things that were preventable. That's what drives me. Onix gets my thinking to people when it can still change the outcome. "

The ICU Doctor Keeping You Out of the ICU

" Most parents are told to choose between the doctor and their gut. I've spent my career proving you don't have to. The science of integrative pediatrics meets you where you are, and that's exactly what Onix makes possible at scale. "

Joel "Gator" Warsh, MD

The Integrative Pediatrics Bridge Builder

" I stand here today knowing it can happen, but I hadn't believed it the whole way. It's been amazing to watch it prove out: to have conversations with AI that harness exactly the way I'd want to see a patient, and to stop at the place where it's not appropriate and refer them on. "

Ashley Koff, RD

" I was skeptical of digital medical advice. Then Jordan Metzl's onix actually changed my behaviour, and no app has ever done that. "

" After almost 30 years of being dismissed about my thyroid, McCall's onix coached me exactly how to advocate for myself. My doctor did a complete 180, and I can't imagine that outcome without McCall and Onix. "

" It felt very real. I was torn between my daughter's one-size-fits-all program and the expert who so thoughtfully built something just for her. "

" I feel like this doctor is one of my biggest supporters, and I've never even met him. "

" For twenty years I tried to change my brain instead of accepting it, thinking I just wasn't capable. This gave me clarity, and hope. "

" I felt like I was speaking to a medical professional who was actually interested in me. "

" I'm not an AI guy, I like old school. But Onix put Mark in my pocket. I can ask him a question in the middle of the grocery store and the answer's right there. "
