About AOO

A coalition of clinicians, advocates, and Arizonans — built to change obesity care in this state.

The Arizona Obesity Organization exists because obesity is a chronic disease, and Arizona has yet to treat it like one. We're working to change that.

Our Mission
"To ensure every patient affected by preobesity and obesity in Arizona receives evidence-based treatment and coverage for their care."
Our story

Why we started AOO

Obesity is the most common chronic disease in Arizona — affecting nearly four in ten adults — and yet it remains one of the least treated. Walk into any Arizona primary care office and you'll find clinicians who want to help patients with obesity but don't know where to start. Walk into any Arizona pharmacy and you'll find anti-obesity medications that work, paid out of pocket because Medicaid won't cover them. Walk into the state legislature and you'll find few champions for a population that has been told for decades that their disease is a personal failing rather than a medical condition.

The Arizona Obesity Organization was founded by obesity medicine physicians who refused to accept this status quo — and has since grown into a multidisciplinary coalition that now includes surgeons, pharmacists, dietitians, and public health leaders. We came together because no single clinic, no single payer, and no single specialty can solve the problem alone — and because Arizona deserves an organization built specifically for the unique challenges of treating obesity in this state.

"Every Arizona clinician should either be equipped to treat obesity themselves — or know exactly where to refer the patient who walks into their office."

Our tagline — Treat or Refer — is the clinician's covenant. It's a simple promise: no patient with obesity should leave an Arizona exam room without a path forward. AOO exists to make that promise possible — by educating clinicians, advocating for coverage, building the coalition, and giving patients a voice in the policy decisions that shape their care.

We are a 501(c)(3) nonprofit organization, governed by a volunteer board, sustained by membership dues and philanthropy, and accountable to the Arizonans we serve. Our work touches four areas: clinical education, insurance and policy advocacy, community engagement, and coalition building across the medical, payer, employer, and political fields.

This is the work. We hope you'll join us.

What we do

Four pillars, one mission

Every initiative AOO undertakes maps to one of these four areas — the work it takes to change how Arizona cares for people with obesity.

PILLAR 01

Clinical Education

Equipping Arizona clinicians with the tools, protocols, prior-authorization pathways, and CME they need to treat obesity as the chronic disease it is — or to refer patients with confidence.

PILLAR 02

Policy & Advocacy

Producing the evidence base — our white paper, payer trackers, and coverage analyses — that legislators, payers, and employers need to expand access to evidence-based obesity care in Arizona.

PILLAR 03

Community Engagement

Standing with Arizonans affected by obesity — fighting stigma, raising awareness, and giving patients and families a voice in the policy decisions that determine whether they get care.

PILLAR 04

Coalition Building

Convening clinicians, payers, employers, pharma partners, and policymakers around the shared goal of making obesity a treated condition in Arizona — through the Arizona Obesity Collaborative and beyond.

Our vision

Where we're headed

"We envision an Arizona where every clinician knows how to treat obesity — and every patient has the coverage to receive that treatment."

  • I.

    Coverage parity for AOMs across Arizona payers

    Anti-obesity medications covered under Medicaid, commercial plans, and employer benefits — at the same level as treatments for other chronic diseases.

  • II.

    Obesity treatment within reach of every Arizonan

    A statewide network of trained clinicians — physicians, PAs, NPs, pharmacists, dietitians — supported by AOO education and resources.

  • III.

    Obesity treated as a chronic disease in Arizona healthcare

    Coding, reimbursement, clinical protocols, and quality measures that reflect obesity's status as a medical condition — not just a lifestyle issue.

  • IV.

    A measurable reduction in obesity-related disease burden

    Lower rates of obesity-driven diabetes, cardiovascular disease, and mortality across Arizona — particularly in underserved and Medicaid populations.

In the community

Showing up — not just on paper.

Policy documents, prior-auth pathways, and white papers matter. But so does walking with our patients, sponsoring community wellness events, and being visible to the Arizonans we serve.

AOO board members regularly participate in obesity-related community events — wellness walks, advocacy days at the state capitol, patient education forums, and partner-organization gatherings. Because the work has to live in the community, not just in the literature.

Treat or Refer is the clinical promise. Showing up is the community promise.
