Ten Years of Yes.
Inside the decade-long evolution of FxMedSupport — from a supplement startup into the integration backbone behind hundreds of functional medicine practices on Cerbo. A conversation with founder Kevin Mackey on what the Cerbo community taught him, why “I wish” became the most important phrase in his vocabulary, and what comes next.
Kevin Mackey did not set out to build an integration company. He set out to ship supplements. In 2016, the founder of what was then called NutrimentRx noticed something that sounds, in retrospect, almost impossibly mundane: the supplement stores his medical practice was sending patients to were collecting a 26 to 30 percent margin on every order. By drop-shipping those same supplements directly through his own infrastructure, he could capture closer to 50 percent — and pass meaningful operational efficiencies back to the providers.
It was an unglamorous insight. It was also the first thread in what would become a ten-year unraveling — and re-weaving — of how small functional and integrative medicine practices run their operations. The supplement margin was the door. What Mackey discovered when he walked through it was that the practices on the other side of that door were drowning. Drowning in manual work. Drowning in disconnected systems. Drowning in the gap between what their EHR could do and what they actually needed it to do.
Today, ten years later, that same company — now called FxMedSupport — operates more than 80 production applications and integrations serving over 300 functional and integrative medicine practices running on Cerbo. The Cerbo community calls Mackey and his team “the DreamMakers” — a title bestowed not by the EHR itself, but by the providers and clinics whose “I wish my system did this” moments became, with FxMedSupport’s help, working software.
And in May 2026, sitting on a decade of accumulated insight into what medical practices actually need — not what they ask for, but what they need — Mackey is shipping the most ambitious release in his company’s history. Four flagship launches dropping inside a single month. A complete redesign of the FxMedSupport experience inside Cerbo. And what Mackey describes, with unusual conviction for a founder who tends to undersell, as FxMedSupport 2.0 — a fundamental shift in who we are.
We sat down with Mackey to ask how a supplement drop-ship pivot became the integration backbone of an entire EHR community, what he’s learned about software and humans in ten years, and why now — with everything still to build — he calls this the most exciting moment of the journey.
From supplements to software.
Take us back to 2016. NutrimentRx wasn’t an integration company. What were you actually building?
We were sending our patients to external supplement stores, and those stores were giving us a 26 to 30 percent profit margin. I realized that if we built our own drop-ship store and sent it directly to our patients, we’d immediately get a 50 percent margin. So that was the very first piece. That was the original problem we solved.
But then I started watching how my own virtual medical practice was running. I’d watch how long it took us to create a virtual appointment, then jump to Zoom, create a video link, come back, paste it into Cerbo, send it to the patient. And I just kept thinking — this is so much manual work for something that should be automatic.
So I started building the next thing. And then I realized: every time we schedule an appointment, eventually we create an encounter. Why not just auto-create the encounter? And that became Auto Encounter. Which evolved into Auto Chart Prep. Which evolved into the next thing. And the next. And the next.
I didn’t sit down one day and decide to start an integration company. I just kept solving the next problem. One after another. For ten years.
At what point did NutrimentRx — a supplement company — stop being a supplement company?
I had pivoted into being a medical consultant on Cerbo — back when it was called MDHQ. I became an expert on that platform: customization, onboarding, functionality. I learned that for almost every action in Cerbo, there were three or four different ways to accomplish the same workflow. So I was the guy practices would call when they had a special situation — when they needed someone who knew the platform deeply enough to find the right path.
And along the way, as a consultant, every single practice I worked with needed something built. A new tool. A specific way to leverage a feature. A new integration. An optimization. And one day I looked up and realized — I’m not a supplement company anymore. I’m not a consultant anymore. We are the premier eminent medical technology integration company on Cerbo.
That was the rebrand. NutrimentRx became FxMedSupport in 2019. Same company, same mission, but now we knew what we actually were.
I didn’t sit down one day and decide to start an integration company. I just kept solving the next problem. One after another. For ten years.
How the community gave Mackey his title.
Somewhere between 2019 and 2022, providers started calling FxMedSupport “the DreamMakers of Cerbo.” The phrase wasn’t coined by Mackey, by a marketing agency, or even by Cerbo itself. It came from the community — from the providers who kept watching their “I wish I had this” wishes turn into actual working features.
Mackey is careful — almost reverent — about the distinction.
The “DreamMakers” name. Where does it actually come from?
The Cerbo community gave us that title. Not Cerbo. Not us. The providers and the practices we serve. Because every single application in our catalog started with a real provider saying “I wish Cerbo did this.” They asked. We listened. We built. And then we made it available to every other practice that ever wished for the same thing.
That’s the whole story. There’s no marketing trick to it. Auto Encounter Pro started because a provider wished her chart could be pre-built before she walked into the room. Portal Scheduler started because a clinic wanted patients to book appointments without logging in. QuickBooks Online started because a practice was tired of manually keying transactions twice. Every. Single. One.
We are modular because we grow with the community. We don’t have a static roadmap drawn up in a conference room by people who’ve never run a clinic. We have a living catalog that grows every time a real practice brings us a real workflow problem.
Most software companies push toward replacing human work entirely. You don’t talk that way. Why?
I will never commit to “we’ll save you twenty hours a week.” That’s not how this actually works, and I refuse to lie to providers about it. What our software does is help you find the redundancies that your human team is doing day in and day out. You look at the unique patient filters that drive each decision, and you build an automation to do the repetitive part.
Do that enough times and yes — you save minutes. Then minutes become ten minutes. Then twenty. Then thirty. Eventually an hour. Over time. It’s not a flip of a switch. It’s a slow accumulation of reclaimed capacity.
And I never — ever — believe our software replaces people. That’s why we call our philosophy “85% Awesome.” We solve 85 percent of what most independent functional and integrative practices need. The remaining 15 percent — the human element — that’s where the real medicine happens. When Auto Chart Prep drafts a chart, it should never just go straight to the provider unreviewed. The medical assistant should look at it and say, yes, the automation got it right. That’s the perfect 15. The judgment. The care. The human seeing the patient as a person.
We free up smart people to act at the right moment. We don’t replace them.
Cerbo is the best EHR in functional medicine. Always has been. We are honored to make it better. Nobody leaves Cerbo, and nobody leaves us.
Why FxMedSupport doesn’t compete with Cerbo.
The honor we get to hold is that Cerbo is the greatest EHR there is. I run a software company. I understand no software company is perfect, no EHR can do everything. But what Cerbo does, it does better than anyone else. They are the premier eminent product in their class. They are in a league of their own.
We just honorably get to make them better. And because nobody leaves Cerbo, nobody leaves us. We have a very, very low cancellation rate because Cerbo is the best EHR. We make it better. And we’re all moving forward together.
It really is a beautiful, cohesive partnership. A family. Everybody looking out for each other to make sure we’re here for the patients ultimately, and then for the shared clients between FxMedSupport and Cerbo. As long as we keep providing exceptional customer service and our applications keep being what the Cerbo community wants — we’re just honored to be here.
The micropractice revolution.
Ask Mackey what moment, in ten years of building, he’s most proud of, and he doesn’t reach for the obvious answers. He doesn’t talk about revenue milestones or partner status or the size of the catalog. He talks about the smallest practices.
What’s the moment in this decade that means the most to you?
The most inspirational part — the part that genuinely makes me happy — is when we realized we had built something that could bring enterprise-level tools to the smallest practices. The micropractices. The mom-and-pop clinics. The two-provider, one-MA shops that never could have afforded the kind of software stack a hospital system gets.
We give them the same tools. Same automations. Same integrations. And as they grow, they can connect into enterprise-level platforms whenever they’re ready. But we made it possible for the small practice to achieve the goals they’re looking for — without needing to be a big practice first.
That’s the part of this I’m proudest of. Not the size of the catalog. Not the number of practices. The fact that a solo functional medicine doc with a single MA can run with the same operational capability as a clinic ten times their size. That’s worth ten years.
The proof point is concrete. One longtime client of FxMedSupport’s — a functional medicine practice that started with a handful of providers — has, since adopting the FxMedSupport stack, reported approximately 60 percent reduction in operational costs and revenue growth approaching 3x. The practice didn’t replace its team. It freed its team to spend more time with patients and less time clicking buttons.
That’s the math Mackey thinks about. Not the abstract one. The concrete one. Reclaimed minutes. Reclaimed hours. Reclaimed capacity.
How does a small practice actually use what you’ve built? Concretely?
You consolidate. Five, six, seven, ten different software subscriptions you’re paying for? Cancel most of them. You probably don’t need them anymore. We’ve integrated the ones that matter.
You automate the redundant. The same email that goes out after every new-patient registration? Automated. The chart prep before each visit? Automated. The transaction posting to your accounting software? Automated. None of it is glamorous. All of it is real time back in your day.
And — this is the most important part — if any of our applications don’t do exactly what your practice needs, we have the Request for Development process. We can bend, twist, and modify every single thing we have so that it can be utilized best by you and your medical practice. The vision you have for your practice — regardless of size — is the vision we build toward.
FxMedSupport 2.0.
For ten years, Mackey says, FxMedSupport’s posture was reactive in the best possible sense — building exactly what the community asked for, one “I wish” at a time. May 2026 marks the moment that posture shifts.
You’re calling this FxMedSupport 2.0. What changed?
For a decade, when a Cerbo provider said “I wish I had this,” we said yes. We earned the title of DreamMakers because we built what we were asked for. But somewhere along the way, something shifted. After ten years inside hundreds of practices — listening, building, optimizing, watching what actually moves the needle — we learned something nobody else in this space could have learned. We learned what medical practices truly need. Not what they ask for. What they need.
So we’re done waiting to be asked. FxMedSupport 2.0 isn’t an update. It’s a fundamental shift in who we are. We’ve completely redesigned the FxMedSupport experience inside Cerbo — modern, beautifully crafted, engineered to match the power of the EHR it lives within. Because the best EHR in functional medicine deserves an integration suite built to elevate it. Every interaction. Every workflow. Every detail.
And we’re shipping four hero releases simultaneously as part of this generation. Each one solving something we’ve watched practices wrestle with for years.
The hero release: Patient Portal Health Insight.
Every Cerbo practice has years of beautifully captured patient data sitting in their system. Vitals. Labs. Medications. Supplements. Interventions. The data has always been there. Patient Portal Health Insight gives that data a new way to speak.
The application turns the rich patient history already living in Cerbo into a longitudinal visual story of a patient’s health journey — vitals and lab markers graphed over time, with interactive overlays showing exactly when a medication started, a supplement was introduced, or a protocol changed. Sit across from a patient, pull up their entire journey, and point at the chart: “Look. This is when we started this. Look what happened.”
One button generates a beautiful PDF Patient Journey Report — complete with an editable executive summary built from the patient’s lab markers in Cerbo. Edit it, refine it, lock it into the chart forever.
Heidi Health Scribe — bidirectional integration.
Until now, getting Heidi Health Scribe to produce a great encounter required work. Manual uploads. Copy-paste. Context-gathering before every appointment. The provider became a data entry assistant for their own AI. The new FxMedSupport ↔ Heidi bidirectional integration eliminates every manual step.
Set a time before each appointment, and FxMedSupport automatically sends every relevant piece of Cerbo patient data to Heidi: demographics, medications, supplements, active plans. A new Context Folder System inside Cerbo lets any folder become contextual data Heidi receives. The FxMedSupport Provider Context Library goes further — build custom categories like Female Hormone Optimization, Thyroid, Gut Protocols, upload your supporting clinical documentation, tag your patients, and Heidi automatically pulls in every piece of supporting context for that patient’s profile.
Multiple tags? No problem. Patients are complex. Care is complex. Heidi gets the full picture. When the encounter is done, Heidi’s chart flows back into Cerbo for review, edit, and sign — automatically.
Cerbo Visual Reporting Insight.
Cerbo’s reporting engine is incredible — powerful, accurate, comprehensive. FxMedSupport gave that data a new dimension. Imagine logging in tomorrow morning and seeing in one beautifully designed dashboard exactly what’s happening in your practice: active prescribers, active patients, weekly appointments, scheduled utilization by practice and provider, revenue, highest-grossing appointment types, top-selling items.
Then imagine those reports — the ones your practice manager, billing team, and operations lead actually need — landing in their inboxes automatically. Daily. Weekly. Monthly. Quarterly. Whatever cadence you set. Pick the reports. Title them. Choose the recipients. Set the frequency. Beautiful PDFs delivered to the right people, at the right time.
Most practices are making decisions about their business without seeing the full picture. They’re guessing at utilization. Estimating revenue patterns. Wondering which services move the needle. This is the visibility.
And one more: FxMedSupport Blade.
The fourth release is the foundation underneath everything else: a complete redesign of the FxMedSupport application experience inside Cerbo. Modern. Beautifully crafted. Engineered to match the power of the EHR it lives within. Every interaction, every workflow, every detail rebuilt to elevate Cerbo into even more of what it already is.
This is the platform every practice on FxMedSupport will use, every day, for the next decade.
The next decade of yes.
Ten years in, with four flagship releases shipping in a single month and a complete platform redesign, you might expect Mackey to be in victory-lap territory. He is not.
After all this — what comes next?
Honestly? More of the same. More “I wish.” More yes. More practices stepping into operational capability they didn’t think they could have. The Request for Development backlog never gets shorter, and that’s the best news I can tell you. As long as there are providers with workflows they wish were better, we have work to do.
The May 2026 release is the biggest moment of our decade. It’s also the foundation for the next one. FxMedSupport 2.0 — and the four releases shipping with it — give us a platform we can build on for the next ten years. The same way the last ten years built on a supplement drop-ship store and a guy noticing manual Zoom links.
We don’t know exactly what the Cerbo community is going to ask for next. We just know they’ll ask. And we’ll say yes.
That, finally, is the through-line of FxMedSupport’s decade. It is not a story about software. It is not, despite what the catalog and the integration count might suggest, even primarily a story about technology. It is a story about a founder who decided, ten years ago, that the right answer to “I wish my system could do this” was almost always yes — and then spent ten years figuring out how to keep that promise at scale.
On the other side of those ten years sits a company with 80 production applications, more than 300 practices, four flagship May 2026 launches, and a platform redesign that earns the name FxMedSupport 2.0. On the other side sits a community of providers who, somewhere along the way, decided to call the company they trusted with their workflows the DreamMakers.
And on the other side sits Kevin Mackey — still, by his own description, just solving the next problem.
