Our philosophy
Hi, I'm Dr. Halberg.
I founded Longeva after fifteen years in internal medicine watching patients hand over their health to a system designed to manage disease, not extend life.
We built something different. Every member receives a comprehensive baseline panel, a clinician who actually has time to know them, and protocols rooted in peer-reviewed science.
This isn't wellness. It's medicine, practiced the way it should be.

A SIGNATURE UNFLD® EXPERIENCE
Hands-on care.
Personal training.
One focused hour.
When an area feels tight or restricted, give it focused attention and put it to work. UNFLD® Bodywork combines targeted hands-on muscle and fascia work with personalised training, guided by a movement specialist throughout.
Begin with around 15–20 minutes of hands-on work tailored to your needs. Then move straight into exercises selected around your goals, combining mobility, movement control and strength.

FOCUS
Identify what needs attention and what you want to improve.
02
RELEASE
Targeted hands-on work for the muscles and surrounding connective tissue.
03

MEET SENAI · FOUNDER OF UNFLD®
Why I’m building UNFLD®.
Having worked in demanding corporate environments, I know how easily looking after yourself becomes something you’ll get to later.
I’m building UNFLD® to make that routine easier to create and maintain: a welcoming place to build strength, recover and receive guidance from people who know you.
My ambition is simple: to help you feel stronger today and stay capable for years to come.
Senai
Founder, UNFLD®

Average member outcome

Reduction in biological age across members, as measured by epigenetic panels.
"
For twelve years I was told my symptoms were just stress. Healthio ran one panel and found what three doctors missed. Three months in, I feel like myself again.
Marcus Bennett

"
My GP told me I was fine. My Longeva panel found three deficiencies and a metabolic issue nobody had caught. Six months on the protocol and my energy is back.
Elena Castellanos

"
The difference is the time. My clinician knows my whole story. Every protocol change makes sense because it's built on a year of data, not a 12-minute consult.

The UNFLD Protocol™ connects these steps, giving your training a clear direction while allowing your plan to evolve with you.
