Today we’d like to introduce you to Vivian Asamoah.
Hi Vivian, please kick things off for us with an introduction to yourself and your story.
My journey into medicine began far from Houston — it started with a deep curiosity about the human body and a calling to serve that took me across continents. I earned my Medical Doctorate from the University of Geneva in Switzerland, with early clinical exposure spanning Switzerland, Ghana, and South Africa. That international foundation shaped how I see medicine — not as a one-size-fits-all practice, but as something deeply personal, cultural, and rooted in the whole person.
After completing my Internal Medicine Residency at Johns Hopkins Bayview Medical Center and my Gastroenterology and Hepatology Fellowship at Johns Hopkins University School of Medicine, I came to Houston and joined Cypress Fairbanks Gastroenterology & Associates, where I focused on liver disease, inflammatory bowel disease, and colorectal cancer prevention. But something kept pulling at me. I kept seeing patients who weren’t getting better with conventional care alone. They were symptomatic, frustrated, and underserved by a system focused on managing disease rather than finding its root cause.
That conviction led me to take a leap of faith in 2014 and found Houston Gastro Institute in Katy, TX. What started as a vision has grown into one of Houston’s leading outpatient GI practices — a team of physicians, nurse practitioners, and registered dietitians delivering care that treats the whole patient, not just the diagnosis. In 2018, I became Medical Director of Zazen Surgery Center, a physician-owned ambulatory endoscopy center I built with a specific mission: same-week scheduling, affordable self-pay rates, and selective insurance contracting that actually serves our community. Even the name — Zazen, a form of seated Zen meditation — was intentional. In a space where patients often arrive anxious, I wanted the environment itself to communicate calm.
But I wasn’t done evolving. I became a Certified Functional Medicine Physician through the Institute for Functional Medicine — a credential that formalized what I had long believed: that lasting healing comes from addressing the root cause, not just the symptom.
That same conviction led me to build something beyond the clinic walls. Today my educational platform reaches nearly 300,000 people across Instagram, TikTok, Facebook, YouTube, LinkedIn, and a 10,000-person email community — all dedicated to evidence-based gut health education, microbiome science, and honest conversations about where gastroenterology is evolving. In 2024, I launched Dr. Vivian Asamoah PLLC, a direct-pay virtual integrative and functional medicine GI practice now serving patients across fifteen states, with North Carolina as our newest addition.
Today I practice at the intersection of precision gastroenterology, therapeutic nutrition, and mind-gut medicine. I’m proud of the nearly 2,000 five-star reviews, the national recognition, and the awards — but what drives me every single day is the patient who finally gets answers after years of suffering. That’s the story I’m still writing.
Would you say it’s been a smooth road, and if not what are some of the biggest challenges you’ve faced along the way?
Smooth? Not even close. And I wouldn’t trade the hard parts for anything, because they shaped everything I’ve built.
One of the earliest and most persistent struggles was simply being taken seriously for the kind of medicine I believed in. When I began incorporating nutrition, functional testing, and root-cause thinking into my gastroenterology practice, I was met with skepticism — sometimes from colleagues, sometimes from the broader medical establishment. Integrative medicine wasn’t exactly welcomed with open arms in traditional GI circles. There were moments where my approach was dismissed as “not evidence-based enough” or “outside the standard of care.” For a physician trained at Johns Hopkins, that kind of pushback stings. But it also fuels you.
I remember a patient — a well-educated, well-researched patient — who sat across from me in the exam room and told me that leaky gut was misinformation. That what I was describing wasn’t real medicine. I sat with that. And then I kept going. Because weeks later, that same patient came back. And they were better. The science doesn’t need defending when the patient is standing in front of you, finally feeling like themselves again.
There were genuine moments of self-doubt. Am I doing the right thing? Am I putting my reputation on the line for an approach the mainstream isn’t ready for? But then another patient would come in — someone who had seen five other physicians, been handed prescriptions that masked their symptoms for years, been told everything looked normal — and they would finally get answers. That kept me going.
Building Houston Gastro Institute from the ground up in 2014 came with its own set of challenges. Starting a practice means you are suddenly not just a physician — you are an employer, an administrator, a strategist, and a financial decision-maker all at once. I learned that on day one. Literally. On the first morning we opened our doors, my new medical assistant slipped a note under my door, left her key, and walked away before we ever saw a single patient. My husband — an emergency medicine physician — became my MA that day. He checked in patients, handled the front desk, and kept things moving while I saw every person on that schedule. We laugh about it now. But in that moment, I understood exactly what I had signed up for. You build it anyway.
Insurance was its own battle. Negotiating contracts as an independent physician, fighting for fair reimbursement, deciding which payers actually serve your community and which ones don’t — that is a relentless, unglamorous fight that never fully ends. It requires you to be a businesswoman as much as a physician, and nobody trains you for that in medical school.
Scaling a team brought a different kind of pain. Growth sounds exciting until you are in the middle of it — navigating staffing challenges, building culture from scratch, learning that not every partnership survives the distance. I’ve learned that partnerships are like a marriage. Good intentions are not enough. Alignment — in values, in vision, in work ethic, in philosophy — is everything. Some of the most painful lessons of my career have come from partnerships that began with the best of intentions and fell apart because the foundation wasn’t built on the same beliefs. I’ve made peace with those seasons. They clarified exactly who I am and what I will and will not compromise on.
And as a Black woman in gastroenterology — a specialty that remains one of the least diverse in medicine — there were spaces where I had to work twice as hard to be heard, to be respected, and to be seen as the expert in the room. That is a reality many of us don’t talk about enough. But it is part of my story, and I won’t leave it out.
What carried me through all of it was an unwavering belief that patients deserve better than symptom management. They deserve a physician who will dig deeper, ask harder questions, and walk alongside them toward real healing. Every time I doubted myself, that belief pulled me back to center.

Thanks – so what else should our readers know about Houston Gastro Institute?
Houston Gastro Institute is more than a GI clinic. It is a place where patients come when they are tired of being told their labs are normal but they still don’t feel well.
We are a top-rated outpatient gastroenterology practice located in West Houston. We specialize in the full spectrum of digestive and liver health — from colonoscopies and upper endoscopies to the management of complex conditions like inflammatory bowel disease, fatty liver disease, IBS, SIBO, colorectal cancer screening, and advanced hepatology. Our growing team of physicians, nurse practitioners, and four registered dietitians work side by side, because we believe that a gastroenterologist and a dietitian in the same room can change a patient’s life in ways that neither could accomplish alone.
We serve over 8,000 patients annually, and our care model is built around one powerful idea: find the underlying driver, not just the symptom. We are known for being the clinic that listens. Patients come to us from across Houston and beyond, many having already seen multiple specialists without resolution. We take the time. We run the right tests. We build a plan that is personal, evidence-based, and sustainable.
Alongside HGI, I also operate Dr. Vivian Asamoah PLLC — a fully integrative and functional medicine GI practice that is completely separate from the insurance system. This is where patients come knowing they want a different approach. A deeper, more nuanced look at their gut health — one that addresses nutrition, the microbiome, lifestyle, stress, and the underlying drivers that conventional workups don’t always capture. This practice is insurance-free and currently serves patients across fifteen states, meeting people wherever they are in their healing journey.
We are also growing in ways that reflect our commitment to this community. HGI is expanding into Fulshear, bringing the same standard of care to a rapidly growing part of the greater Houston area. Our team is diverse — intentionally so — because we serve one of the most culturally rich cities in the country, and we believe our patients deserve to see themselves reflected in the people caring for them.
What I am most proud of is our reputation for trust. With nearly 2,000 five-star Google reviews, Houston Gastro Institute has become a name patients recommend to their families, their friends, and their communities. We have been recognized as Best in Katy, Best in Houston — including again in 2026 — and Best in Texas, honors that belong just as much to our team as they do to me. This year, I was also named a Houstonia Top Doctor 2026, a recognition that reflects the standard of care this entire team delivers every single day.
If you have been struggling with digestive issues, liver concerns, bloating, gut pain, or chronic GI symptoms that haven’t responded to conventional treatment, there is another way. You don’t have to keep managing symptoms indefinitely. Between Houston Gastro Institute and Dr. Vivian Asamoah PLLC, we have built two distinct paths to get you there — and we are ready to walk alongside you on either one.
Can you talk to us a bit about the role of luck?
I have thought a lot about this question, and honestly, I am not sure I believe in luck in the traditional sense. What I do believe in is divine timing, preparation, and the power of people — and when all three converge, what looks like luck from the outside is really something much deeper.
There have been moments in my journey that I can only describe as God-ordained. Leaving the security of an established practice in 2014 to found Houston Gastro Institute was a leap that, on paper, carried enormous risk. The timing wasn’t perfect. The road wasn’t clear. But doors opened that I hadn’t knocked on, and connections formed that I hadn’t engineered. I have learned to recognize those moments not as coincidence but as confirmation that I was walking in the right direction.
At the same time, I have never believed in waiting for luck to arrive. My training at Johns Hopkins taught me that excellence is not accidental — it is built through discipline, curiosity, and relentless preparation. Every certification I pursued, every skill I added, every system I put in place at Houston Gastro Institute was intentional. I wanted to make sure that when opportunity came, I was ready to receive it. And it did come — but only because the work had already been done.
And then there are the people. If I am being honest, some of the greatest turning points in my journey came because the right person believed in me at the right time.
Dr. Shanthi Sitaraman, who mentored me early in my career, showed me what it looked like to pursue scientific excellence without losing your humanity. He modeled what it meant to ask hard questions, stay curious, and never settle for a surface-level answer — values that are woven into everything I do today.
Dr. Gerry Mullin opened a door I didn’t know existed. He was among the first to show me that a gastroenterologist could also be an integrative medicine physician — that those two worlds didn’t have to be in conflict. That permission changed everything about how I saw my own path.
And my mother. She was there for every exam, every test result, every failure. She never tried to fix it or explain it away. She just showed up — and she always said the same thing: keep going. In the moments where the doubt was loudest, her presence was the steadiest thing I had. I would not be here without her.
I do not take any of these relationships lightly. The people who have shown up in my life and in this practice have been nothing short of a gift.
So was it luck? Maybe some would call it that. But I call it faith that kept me moving, preparation that kept me ready, and people that kept me grounded. That combination — not luck — is what Houston Gastro Institute is built on. And it is what will carry us into everything that is still to come.
One day, I hope to be that person for someone else. The mentor who opens a door. The voice that says keep going. That is the part of this journey I am still most looking forward to.
