FMCA Certified · IFS Foundations for Coaches™ · Bay Area, California · Virtual Worldwide
Functional medicine health coaching and IFS parts work — for people who know what they need to do and can't get themselves to do it. And for people on GLP-1 who want to build real, lasting vitality — not just lose weight.
"The gap between knowing what to do and actually doing it isn't a discipline problem. It's a protection problem."
— The premise everything here is built on

Who I am
For years I worked as an imaging aide — present for scans, results, prognoses, the quiet moments people found out what was happening inside their bodies. I watched brilliant treatment plans handed to patients who never followed through. I watched others with worse odds get well.
The difference was almost never the medicine. It was whether the person was working with themselves or against themselves — whether the parts running their internal system had been met, understood, and given something better to do than protect the old wound.
I trained in functional medicine through FMCA and bring an IFS parts work lens to every engagement. I work with the biology directly — labs, body composition, food, movement, metabolic health. And I work with the internal system running it, because no plan, however well-designed, survives a part of you that isn't on board.
My clients are driven, self-aware people who have tried the protocols and keep finding themselves back at the beginning. And people navigating GLP-1 who want to use that window to build a body and a relationship with food and movement that lasts beyond the prescription.

Who I work with
Not beginners. People who know what to do, have tried it, and keep running into the same invisible wall.
Driven, capable, invested in their own growth — and somehow still back at square one with their health. Not for lack of trying. For lack of the right kind of work.
On semaglutide or tirzepatide and determined not just to shrink — but to build. Muscle, strength, metabolic intelligence, and a protocol that outlasts the prescription.
Labs, wearables, assessments — and still no clear picture of why the plan isn't landing. They need someone who can work with the biology and what's running it.
Has seen doctors, therapists, coaches. Something always gets in the way. Usually a part that hasn't been met properly yet — not a failure of discipline or intention.
Ways to work together
Each pathway is built around a different person and a different moment. The work underneath all three is the same.
Flagship Program
12–16 weeksThe original container. Functional medicine health coaching paired with IFS parts work — for high-functioning people who've tried the protocols and keep finding themselves back at the beginning. We work with the biology and the part of you that's been protecting something.
Specialist Program
16 weeksBuilt specifically for people on GLP-1 who refuse to just get smaller. A structured 16-week system covering muscle preservation, strength benchmarking, NEAT tracking, and a 6-week elimination protocol to surface the food sensitivities your medication has finally made visible.
Bespoke Coaching
Flexible containerFor people whose situation doesn't fit a defined program — or who want a fully personalised engagement built entirely around their physiology, their parts, and their goals. Same coaching depth, different structure. We design the container together.
How it works
Apply
A short, honest application. Not to impress — to help both of us understand if this is the right fit and the right moment.
Discovery call
A 45-minute conversation. We map your situation, your biology, and the parts in the way. No pitch — a real read of whether this works.
The container
12 to 16 weeks of structured work — built for your specific system, not a generic template. The arc has a beginning, a middle, and a graduation.
Graduation
You leave with a protocol you own, a parts literacy you can return to, and data proving something actually changed. Not dependent on me continuing.
What clients say
Honestly didn't know what to expect. I'd done the diets, had the lab work, tried the tracking apps. Fermin was the first person who actually asked what was getting in the way — not just what I was eating. Something unlocked after that first month that I hadn't been able to crack in years.
— M.R., Anchored Vitality program
I came in worried I was going to lose all the muscle I'd worked so hard for. By week 8 I was hitting numbers I hadn't seen in two years. The food sensitivity piece surprised me the most — turns out oats were wrecking me every single morning and I had no idea.
— D.W., GLP-1 Vitality Method
I'm a pretty skeptical person so the IFS piece sounded a little out there to me at first. But we kept running into the same wall until we actually looked at what was behind it. Turns out the eating wasn't the problem. Three months later I'm still doing the things I swore I'd never be consistent with.
