Does This Sound Like Your Practice?
Clients who have "tried everything" and still aren't better.
Protocols that work beautifully on everyone else until they don’t.
Labs markers that are in range but clients are suffering. Or Labs are a mess despite comprehensive protocols.
You have a feeling you’re missing something fundamental.
You recognize the rapidly evolving environmental hazards clients are facing and want to be equipped to remediate them.
Standard clinical trainings dedicate about 45 minutes to toxins. Your clients’ need far more than that.
Toxin University™ is the only Advanced Clinical Certification designed to finally give you the tools to address what everyone else is missing.

Every Stuck Case Has a Thread.
Something specific is happening inside every client who won’t get better. Something traceable. Something fixable.
Plastics silently dismantling hormones. Mycotoxins hijacking the nervous system. Heavy metals clogging drainage before detox ever gets a shot. Halogens displacing the exact nutrients their bodies are desperate for.
It’s in the food, the water, the air, the products your clients already trust.
It’s in the chart of every stuck case you’ve ever walked away from.
Once you learn to see it — you can’t unsee it.

- Mast cell escalation
- Biofilm mimicry
That's what this is built to teach.

Bonus Intensive (Special Guest):
The Silent Epidemic
Stopping Nanotech + Synthetic Biology From Overtaking Humanity with Maria Crisler
Some of the most disruptive exposures aren’t showing up on standard toxin training maps yet.
They don’t fit neatly into “mold vs metals vs chemicals.”
They don’t always register on familiar labs.
And they can leave practitioners feeling like something is deeply off… without a clean clinical category to name it.
This special intensive is designed to expand your clinical awareness of emerging synthetic exposures so you can stay grounded, discerning, and effective as the landscape evolves.
Inside this Intensive, you’ll explore:
- What “nanotech” and “synthetic biology” actually mean in practical, clinical terms (what is proven versus conjecture)
- How to think like a clinician in an emerging field: patterns, plausibility, signal vs noise, and staying evidence-aware without becoming reactive
- Where these exposures may drive chronic inflammation, immune dysregulation, neurological symptoms, and detox intolerance
- How to support the body’s terrain (nervous system, drainage, immune tolerance, cellular resilience) when this new tech weaponizes the body’s own healing responses
- How to communicate with clients who are scared, overwhelmed, or spiraling—without dismissing them or feeding fear – and stay solution oriented
Why we included this in Toxin University
Toxin University exists because modern exposure has outpaced modern training.
And part of being the healer you were called to be is being able to:
Stay awake to what’s emerging…
Without losing your grounding.
Without forcing protocols.
Without falling into either denial or panic.
This intensive gives you a wider lens—so you can keep your clinical intuition sharp, your nervous system steady, and your client care rooted in discernment.
A note on tone + approach
This is educational, clinical, and sovereignty-centered—not sensational.
We focus on helping you build a calm, capable framework for navigating complex modern exposures with integrity.
Included as a one-time-only bonus intensive inside Toxin University.
Community + Forum Features
- Case submissions
- “Stuck client” troubleshooting
- Protocol refinement
- Implementation tips
- Monthly office hours/Specialty Q&A sessions
- Expert feedback
Toxin University vs. Other Practitioner Programs
Most practitioner education mentions toxins. Toxin University is built to make you clinically fluent in them so you can finally solve the cases that stay stuck even when “everything looks normal.”
Features
Toxin University
Other Practitioner Programs
Focus
Entire membership
dedicated to environmental
toxicity as a root cause
(not a side note).
Toxins are usually a brief
chapter, a single lecture, or an
optional add-on.
How you learn
Monthly curriculum with a
repeatable structure so
you actually master one
toxin category at a time.
Information is scattered
across topics and hard to
build a cohesive clinical
approach.
Clinical depth
Mechanisms of damage
taught clearly
(mitochondria, hormones,
bile flow, vagus signaling,
immune tolerance, etc.).
Often stays at a high level:
“toxins are bad” without
mapping the physiology.
Finding the real exposure
Systematic sources-of-
exposure breakdown +
checklists (including hidden
“healthy” sources).
Usually focuses on obvious
exposures; misses the subtle
ones that keep clients stuck.
Why labs look normal
Trains you on direct vs.
indirect markers +
symptom pattern recognition
when standard labs don’t
flag the issue.
Labs are treated like the
main proof and if they’re
normal, you’re left guessing.
Protocols that actually hold
Teaches safe, phased detox
protocols designed for
sensitive/reactive clients
(so detox doesn’t backfire).
Detox is often oversimplified,
too aggressive, or not built for
high sensitivity.
Real-world support
Case submissions, stuck-
case troubleshooting, office
hours/Q&A, implementation
guidance.
Support is minimal or ends
when the program ends.
No ongoing clinical
refinement.
Client compliance tools
Client-ready handouts
and materials to improve
follow-through.
Often leaves you to create
your own materials from
scratch.
Outcome
You walk away able to
see the thread in stuck
cases and confidently
intervene.
You walk away with more
knowledge… but not always
a reliable clinical roadmap.

Hear What Practitioners are Saying:
Carla Davenport
L.Ac.
“Sinclair and Michael teach a clear & multi-layered approach to the root causes of the chronic illnesses that plague us and our clients today. It’s not just about selling a bunch of supplements and a one size fits all protocol. But looking deep at the behaviors and environments that got us sick to begin with and how to course correct those in the most supportive and self-loving way possible.
In implementing all that I have learned into my practice, clients that had moderate success with myself and other practitioners in the past are now getting the deep transformative results they were originally seeking and their hope for vibrant health is finally realized.”
Laura Frontiero
NP
“Mentoring with Michael and Sinclair helped me fill in the missing pieces I didn’t learn with the basic functional medicine approach. There’s so much more to know about supporting detox and cellular health that you’ll never learn in a classroom!
I was able to immediately apply the new techniques which resulted in immediate client symptom improvement.
An unexpected result was exponential growth of my business due to finally having protocols that worked!”
Sirena Squires
LMT, CNS
“I have always found the best healers and teachers are those that have gone through it themselves, able to bring forth the wisdom gained from their own experience. Sinclair and Michael are a prime example of this, bringing all their research, trials, errors and successes to each and every one fortunate enough to cross their path. Their approach is also based on being a conscientious witness to others journey towards better health and healing, which has acquired them the ability to know how to adapt protocols for each person’s bio-individualistic needs. Very well rounded, they also bring in the attention that is necessary to give to our mental, emotional and spiritual health for healing. Extremely well researched and well spoken, Sinclair and Michael have their heart and soul in what they offer, caring greatly for the well being of all. ”
Lana Heller
Practitioner (25 years in Practice)
“To have an organized plan and everything presented is absolutely priceless.”
Suzanne Subaitani

“I’m really excited to go through piece by piece and learn the granular details of each heavy metal and each mold.”
Michelle Brown
FNLP, Clinical Herbalist
“People come to me after spending $100,000 on functional medicine protocols and they’re still not making progress.”
Candace Jones
Nutritional Therapy Practitioner
“I love how in-depth you guys are… you answer a lot of the questions before I even have to ask them.”
Julie Engler
FDMP
“That supplement index is just going to be gold.”
Jenn Malecha
FDN Practitioner
“This is the first clinical training I have ever invested in outside of FDN in 2012.”
Halsie Peek
RN, BSN, HWNC-BC
“I feel like I was asking the universe for something like this… and maybe 24 or 48 hours later this offer dropped in my inbox.”
Rheba Casteen
RD, FDN Practitioner
“I love the information. I’m excited about all of it.”
Suzanne Subaitani
MRHP, NTP, 200-RYT
“The clients are getting more and more complex.”
