KOI Wellbeing: an approach to health, in search of root cause.

KOI was founded on a belief: everyone deserves effective, evidence-based, root-cause care, without the limits of insurance-driven medicine.

What we believe

Everyone has the right to experience optimal health, and to access effective care promptly and conveniently. We believe healthcare should be a service where you're treated as a valued individual, not a patient file dictated by insurance constraints.

Writing a prescription for your complaint isn't healthcare, it doesn't address the root cause; it simply masks symptoms and creates dependency. We know there is a better way.

By using advanced laboratory testing to uncover the root cause, and prescribing naturalised options that can be measured for efficacy, we deliver healthcare that actually works, and lasts.

To create a bridge between western and naturopathic medicine, in a positive, supportive environment that leaves people informed and empowered.
Jeffrey Sternberg, founder of KOI
How KOI started

A gap worth closing.

KOI began with a simple observation: too many people weren't getting answers. There was a gap in care, a lack of empathy, and a personal touch lost somewhere between the waiting room and the prescription pad.

Our approach is to make the experience of being a patient about far more than a refill. It is about being heard, being listened to, and having your needs genuinely met.

The calm, welcoming KOI space
Our space

Somewhere you can actually breathe.

We try to mirror that approach in the space itself. We built somewhere welcoming, restful and rejuvenating, a place you can walk into and exhale.

It doesn't feel like a traditional doctor's office, and that is the point. Here, we know you by name, not by medical record number.

The process

It starts with time.

No rushed fifteen minutes here. We start by understanding you, then build from there.

A free 50-minute consult

Real time to be heard. We sit down to understand your history and your goals, with no rush, no pressure and no fifteen-minute clock.

We start with labs

Good care is data-driven, so we begin with the right testing. Already have recent labs? Bring them in, we're happy to work from those.

Your plan, built together

We build your plan with you, not for you, matched to your goals, your body and your lifestyle. It's a collaboration, never a template.

Ongoing care

We retest, adjust and stay with you, so your plan keeps working as you do.

Care that doesn't break the bank

Our goal is to help you, not to charge you. Paying for your care shouldn't be another stress in your life, so we've partnered with Cherry for flexible, easy financing that helps you reach your goals without breaking the bank. Sign-up takes minutes, and checking your options won't affect your credit score.

Our brand & its meaning

Why the koi.

In many cultures the koi symbolises perseverance, transformation and the pursuit of a better life, swimming upstream against the current. It's the spirit we bring to medicine: the determination to look deeper, ask why, and help you become your healthiest self.
