Why PRECISIONBIO?

PrecisionBio integrates advanced diagnostics, cellular-level therapies, and cutting-edge technology to address the root causes of illness and support long-term disease prevention.

Advanced Diagnostics

We use next-generation lab testing, imaging, and molecular analysis to uncover the hidden drivers of chronic disease and dysfunction.

Personalized Protocols

Each patient receives a customized treatment plan based on their unique biology, history, and diagnostic data — tailored solutions for every unique need.

Cellular Therapies

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.

Integrated Technology

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.

Our Approach

Root-cause medicine meets next-generation care. We go beyond symptom management to create lasting change at the cellular and systemic level.

Identify, Don’t Guess

We use deep diagnostics and biomarker mapping to precisely identify the source of dysfunction.

Treat the Terrain

Rather than targeting isolated symptoms, we rebalance the entire internal ecosystem — from the gut to the mitochondria.

Activate Cellular Repair

Our therapies are designed to stimulate regeneration, modulate the immune system, and enhance resilience from within.

Personalize Every Step

Protocols are custom-built for each patient using their diagnostic profile, health goals, and real-time progress data.

Track & Adapt

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.

Our Science

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.

Patient Testimonials

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.

Jackson Randy

Autism

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!

Chris

Back Injury

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.

Sherry

Chronic Kidney Disease / Back & Neck Pain

The doctors at PrecisionBio didn’t rely on just one strategy. Their multi-layered immune approach helped me beat cancer.

Frequently Asked Questions

What conditions do you treat at PrecisionBio?

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.

What makes PrecisionBio different from other clinics or stem cell centers?

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.

How are your treatment protocols personalized for each patient?

Each protocol is developed from in-depth diagnostics, biomarker analysis, and your health history — ensuring it is tailored specifically to your body and condition.

What are cellular therapies, and how do they work?

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.

Is your care focused only on chronic illness, or do you offer wellness and prevention programs too?

In addition to treating chronic illness, we support patients seeking proactive care for anti-aging, performance optimization, and long-term disease prevention.

Is Mexico safe for medical treatment?

Yes — our clinic is located in a secure, modern medical tower in Tijuana, just minutes from the U.S. border. We offer private transportation, vetted accommodations, and a concierge team to ensure your experience is seamless, comfortable, and safe from arrival to departure. Tijuana is the most visited medical tourism destination in the world, welcoming over a million patients annually for high-quality, affordable care.

How long does it take to see results from your protocols?

Some patients experience improvements within days or weeks, while others see more gradual changes over several months depending on their condition and response to treatment.

Where do I stay, where do I eat, and how do I get around during treatment?

We help coordinate accommodations near our Tijuana clinic and offer support with local transportation. Our concierge team ensures a smooth, safe, and comfortable experience throughout your visit. We offer complimentary breakfast and lunch for all patients during treatment days, featuring fresh, nourishing options to support your recovery. Our concierge team is also happy to arrange reservations at Tijuana’s world-class restaurants so you can enjoy the city’s renowned culinary scene in comfort.

How much does it cost?

Because each treatment plan is highly personalized and includes advanced diagnostics and biologic therapies, pricing varies based on your specific needs. Full details are provided during your initial consultation. We do not accept any type of insurance.

Where do the stem cells come from?

Our stem cells are ethically sourced from healthy young women, thoroughly vetted, and free from COVID-19 vaccinations delivering by scheduled C-section at partner hospitals in Mexico. Both the donor and cord tissue undergo rigorous medical screening to ensure purity, safety, and quality.

What experience does your medical team have?

Our Medical Director, Dr. Alberto Peña, leads our clinical team with over two decades of experience in functional, integrative, and regenerative medicine:

- MD from Autonomous University of Baja California
