The journey from conventional medicine to functional healing—and why we built something different.
Every practice has an origin story. Ours began in the exam rooms of conventional medicine, where a young physician named Dr. Mark Su watched patient after patient leave his office still searching for answers.
They weren’t satisfied with their care. More importantly, they weren’t getting better.
When “Normal” Labs Don’t Match How You Feel
After graduating as valedictorian from high school and earning his medical degree from Indiana University School of Medicine, Dr. Su completed his Family Medicine residency at Tufts University—where he received the national Mead-Johnson Award for outstanding scholastic performance. He did everything right. Followed the conventional playbook. Practiced the way he was trained.
But something wasn’t adding up.
Patients came to him exhausted, in pain, struggling with brain fog and digestive issues—symptoms that were very real and deeply impacting their lives. Yet their standard lab work looked “normal.” The conventional system had trained him to say, “Your labs are fine. Maybe it’s stress. Try to get more sleep.”
But Dr. Su knew that wasn’t enough. These patients deserved better than being sent home with a dismissal and a pat on the back.
So in 2003, he began his journey into functional medicine—learning to ask different questions, order different tests, and look for the root causes that conventional medicine often misses. He started seeing patterns. Chronic infections like Lyme disease and tick-borne illnesses. Mold and mycotoxin exposure. Autoimmune conditions triggered by hidden imbalances. These weren’t just symptoms to manage—they were messages pointing to deeper problems.
From One-on-One Care to Something More Powerful
For over a decade, Dr. Su built a successful functional medicine practice on the north shore of Massachusetts, specializing in complex chronic illnesses. He became known for his ability to solve medical mysteries—connecting dots that other doctors missed, creating personalized treatment plans, and helping patients finally get their lives back.
But there was still a problem: he could only help one patient at a time.
And there were thousands of people out there—just like you—who had been dismissed by the conventional medical system. People who’d seen specialist after specialist, spent thousands of dollars on treatments that didn’t work, and felt more isolated and frustrated with every “normal” test result.
They needed what Dr. Su had figured out. But the traditional model of one-on-one functional medicine wasn’t scalable. It was too expensive for many patients. It required constant travel to appointments. And most importantly, it didn’t address one of the biggest factors in healing: community.
The Birth of RootSeek: Healthcare Reimagined
In 2022, Dr. Su founded RootSeek with a radical mission: help more patients get better, faster.
Not through rushed appointments or one-size-fits-all protocols. But through a completely reimagined approach to healthcare that combines:
Comprehensive Lab Mapping → Your Personalized Health Map unifies every lab result—past and present—into a clear, data-driven roadmap. It visually highlights the hidden imbalances driving your symptoms and pinpoints exactly where to begin your healing journey.
Individualized Treatment Plans → No cookie-cutter protocols. Your treatment sequence is designed specifically for your body, your imbalances, and your goals—because healing happens in layers, and we address them in the right order.
Live Cohort Support → Here’s what makes RootSeek truly different: you’re not healing alone. You join a cohort of people who “get it”—led by board-certified providers and certified health coaches. You attend live group sessions, receive one-on-one support through our secure portal, and gain accountability and encouragement from peers on the same journey.
Virtual, Nationwide Access → No more traveling hours to see a specialist. RootSeek is completely online, connecting patients and practitioners anywhere, anytime.
Transparent, Affordable Pricing → Functional medicine shouldn’t cost tens of thousands of dollars. We’ve consolidated the care you’d normally get from multiple specialists into one cohesive, cost-effective program.
This wasn’t just about creating another functional medicine practice. This was about changing the entire experience of being a patient—from isolated and dismissed to supported and empowered.
A Team United by Personal and Professional Mission
Dr. Su didn’t build RootSeek alone. He assembled a team of practitioners, coaches, and staff who share a common thread: many of them found their way to this work through their own healing journeys.
Like so many of our patients, members of our team spent years navigating the medical maze. They saw countless specialists. They were told their symptoms were anxiety, or stress, or “all in their head.” They experienced the isolation that comes with chronic illness—when friends and family stop understanding, and conventional doctors stop believing you.
But when they finally found practitioners who listened, who dug deeper, who believed their symptoms were real and had answers—everything changed. Their personal transformations fueled a passion to help others find the same hope and healing.
This lived experience informs everything we do at RootSeek. We’re not just medical professionals who treat chronic illness from a textbook—we’re people who understand the emotional toll, the financial burden, and the desperate need for someone to finally say, “I believe you, and I have a plan.”
Health Is a Continuum: From Illness to Optimization
Here’s something most practices won’t tell you: health and healing exist on a full continuum, and we help at both ends of the spectrum.
For those struggling with chronic illness → Our programs guide you through a phased healing journey. We start with medical stabilization (our Launch phase), helping your body drain toxins and regulate systems. Then we move to lifestyle integration (our Cultivate phase), where you learn to build sustainable habits that support long-term healing. Finally, you transition to ongoing support (our Resilience phase), where you’ve built the confidence and skills to maintain your health with less intensive oversight.
For those focused on longevity and optimization → Maybe you’ve healed from chronic illness and want to maintain your progress. Or perhaps you’re already feeling good but want to future-proof your health, extend your healthspan, and optimize your vitality for the years ahead. Our Longevity programs focus on hormone health, metabolic optimization, and comprehensive anti-aging strategies—because prevention is just as important as treatment.
Health isn’t binary. You’re not either “sick” or “healthy.” You’re somewhere on a journey, and wherever you are on that continuum, RootSeek meets you there.
