Addiction is loud.
Healing begins in quiet.

If you're reading this for yourself — or for someone you love — you already know how heavy this has become. What you may not know is how different life can feel just a few weeks from now.

Ona was built for the whole story: not only the substance, but the anxiety, depression and trauma beneath it. Our dual diagnosis program treats both together — gently, and at your pace — because lasting recovery demands it.

“Our mission is to help every client step out of the dark, isolated cloud of addiction — and back into their family, their work, and their life.” The Ona Care Team

Mind, body & spirit — treated as one.

A complete path, from day one to day free.

Every treatment plan at Ona is built around one person: you. Guided by ASAM clinical criteria and the evidence-based Living in Balance curriculum.

A new beginning at Ona Treatment Center

You'll be met with kindness, not questions you're not ready for.

Whether you're ready to begin, quietly exploring options, or worried about someone you love — you're welcome here. Tell us how to reach you, and a caring admissions specialist (never a call center) will call at the time you choose.

A real conversation, not a pitch

We listen first. No pressure, no obligation — ever.

Protected by federal law

Your privacy is safeguarded under HIPAA and 42 CFR Part 2 — the federal rule that specifically protects substance use treatment records.

No one is told you called

Not your employer, not your family — no one, unless you ask us to.

Our confidentiality promise: every contact with Ona Treatment Center — verbal or written — is kept in the strictest confidence. Information you share here is used only to respond to your request and is never sold or shared for marketing.
In crisis right now? If you or someone else is in immediate danger, call 911. For emotional or suicidal crisis, call or text 988 (Suicide & Crisis Lifeline) — free, confidential, 24/7.

Request a confidential callback

Takes about 30 seconds. First name is enough — share only what you're comfortable with.

Transmitted securely Never shared or sold No obligation

Thank you. You've taken a real step.

A caring admissions specialist will call you at your chosen time — discreetly, from our team. If you'd rather not wait, we're at (530) 869-6163 right now.

The things people are often afraid to ask.

Will anyone find out I'm in treatment?
Not from us. Your treatment records are protected by HIPAA and 42 CFR Part 2 — a federal confidentiality law written specifically for substance use care, stricter than ordinary medical privacy. We don't confirm you're here to anyone — employer, family, or otherwise — without your written consent. Our secluded 270-acre setting adds physical privacy to the legal kind.
What happens on the very first phone call?
A real person from our admissions team listens to your story, answers questions, and — only if you want — checks your insurance benefits for free. There's no commitment and no pressure. Many people call several times before deciding. That's okay.
How much does treatment cost? Will insurance cover it?
Most private insurance plans and TRICARE cover residential treatment in part or in full. We verify your exact benefits confidentially before you commit to anything, and walk you through every option in plain language — no surprises.
What if I have anxiety, depression, or PTSD too?
That's exactly what we're built for. Ona is a dual diagnosis center: we treat substance use and co-occurring mental health conditions — PTSD, anxiety, depression, trauma — at the same time, because treating one without the other rarely lasts.
Is detox safe? Will it hurt?
Detoxing alone can be dangerous — doing it with us is different. Withdrawal at Ona is medically supervised around the clock, following ASAM clinical guidelines, with comfort medications and caring staff so you're never white-knuckling it alone.
Can my family be involved?
Yes — when you choose. Family systems therapy is part of our program, because addiction affects a family and recovery can heal one. If you're a family member reading this: you can call us too. We'll help you understand what comes next.

The bravest thing you'll ever do
takes thirty seconds.

Pick up the phone. A compassionate admissions specialist is ready right now — day or night. Every conversation is completely confidential.
