Why Tri-Cities Precision Health
Precision medicine — where the mystery of you is revealed, layer by layer
We're all like an onion — layers of story shaped by what we've eaten, what we've been exposed to, and how we've cared for ourselves along the way. Real healing means exploring every layer to reach the core, then rebuilding you to your strongest self. Not a quick fix or a solo effort — a partnership, and a marathon we run together. Affordable membership care, starting at just $199/month.
Time you can feel
Longer appointments and same-week availability mean you are heard, not rushed. Your questions get answered.
Private & secure
Booking, forms, and messaging run through HIPAA-compliant tools, so your health information stays protected end to end.
Meet your provider
Rosita Walker, MSN, ARNP, FNP-BC
As a board-certified Family Nurse Practitioner, Rosie built Tri-Cities Precision Health to bring attentive, evidence-based primary care to the Tri-Cities community — with the time and continuity that modern healthcare too often leaves out.
Every plan of care starts with listening, and continues with a partner who follows through.
Longevity & Healthy Aging
First we learn where you are — to help you get where you want to be
Aging well isn't guesswork. We start with your own data — then build a personalized plan to boost energy, sharpen focus, and help you stay strong for the long run.
Know your biological age
TruDiagnostic biological-age testing shows how your body is really aging — so we can measure progress, not just guess.
Restore energy & clarity
NAD+ and glutathione IV therapy, hormone optimization, and peptides target cellular energy, mental clarity, and vitality.
Root-cause, not band-aids
Genetic methylation & MTHFR insights and functional testing address inflammation, fatigue, and brain fog at the source.
Already have a primary care provider?
You don't have to choose — we're happy to work alongside them
If you already have a doctor you love, that's wonderful. Many of our patients keep their current provider and come to us for the extra time, wellness planning, and functional and integrative support that a busy practice may not have room for.
We're glad to collaborate with your existing care team — sharing labs, notes, and recommendations with your permission — so everyone is working toward the same goal: your health and well-being.
- Keep your current PCP — we complement, not replace, your existing care
- Wellness & prevention — personalized plans to help you feel your best
- Functional & integrative options — a root-cause look at fatigue, inflammation, and what's going on
- Coordinated care — we'll share information with your team, with your consent
