PrecisionBio integrates advanced diagnostics, cellular-level therapies, and cutting-edge technology to address the root causes of illness and support long-term disease prevention.
We use next-generation lab testing, imaging, and molecular analysis to uncover the hidden drivers of chronic disease and dysfunction.
Each patient receives a customized treatment plan based on their unique biology, history, and diagnostic data — tailored solutions for every unique need.
From mesenchymal stem cells to exosomes to T-regulatory cells, our regenerative treatments work at the cellular level to repair tissue, regulate immunity, and restore systemic balance.
We combine the latest in medical technology — including photobiomodulation, IV therapies, PEMF, EBOO, ozone, peptides, laser therapy, and precision supplements — for comprehensive, root-cause care.
Root-cause medicine meets next-generation care. We go beyond symptom management to create lasting change at the cellular and systemic level.
We use deep diagnostics and biomarker mapping to precisely identify the source of dysfunction.
Rather than targeting isolated symptoms, we rebalance the entire internal ecosystem — from the gut to the mitochondria.
Our therapies are designed to stimulate regeneration, modulate the immune system, and enhance resilience from within.
Protocols are custom-built for each patient using their diagnostic profile, health goals, and real-time progress data.
Our team provides continuous follow-up and adjusts protocols based on how your body responds — healing is a unique journey with personalized paths for every individual.

At PrecisionBio, your experience is designed around you. We deliver the most advanced cellular therapies available anywhere — but we are not just a clinic. We are a destination for those seeking true healing, optimal performance, and long-term vitality through personalized, science-driven care.


PrecisionBio’s science is rooted in the vanguard of advanced cellular medicine, combining regenerative biologics, systems biology, and molecular diagnostics to repair and optimize the human body at its foundation. Our clinical framework integrates the latest breakthroughs in immunology, mitochondrial health, and tissue regeneration. By leveraging the therapeutic potential of mesenchymal stem cells (MSCs) and their paracrine signaling vectors, specifically exosomes, we target cellular degeneration at its source.
Every protocol is guided by high-resolution biomarker mapping, allowing us to translate complex biological data into personalized, precision-driven treatments that deliver real, measurable outcomes.
After a vaccine injury led to autism and fierce meltdowns, doctors pushed for iinstitutionalization, but my mom’s relentless efforts guided us to these treatments. Now, I live semi-independently, graduated Suma Cum Laude from college, and work as a bookkeeper for a CPA firm.

I never imagined reversing any part of Alzheimer’s. But now, I’m remembering birthdays, reading books, and feeling in control again.
Linda
Alzheimer’s
I skipped the surgery and got my freedom back. I’m lifting, walking, and sleeping without pain. I loved my hotel and the restaurants in TJ were amazing!

My neurologist is amazed. I’ve regained control over my body. I feel completely transformed.
Rebecca
Multiple Sclerosis
Following my treatment, I’ve been off dialysis since 2020 and living life fully, with stable kidney function… also, my neck and back pain is completely gone from the stem cells.

We treat a wide range of complex conditions including neurological, orthopedic, autoimmune, metabolic, cancer immunotherapy, and post-viral illnesses like Long Covid. We also offer protocols for wellness, prevention, and longevity.
Unlike typical “stem cell clinics,” we use advanced diagnostics, stacked regenerative therapies, and a systems biology approach to create fully personalized treatment protocols that target the root cause of illness.
Each protocol is developed from in-depth diagnostics, biomarker analysis, and your health history — ensuring it is tailored specifically to your body and condition.
Cellular therapies use regenerative biologics such as mesenchymal stem cells, exosomes, peptides, and growth factors to help repair tissue, regulate the immune system, and restore function at the cellular level.
In addition to treating chronic illness, we support patients seeking proactive care for anti-aging, performance optimization, and long-term disease prevention.
