Root-cause medicine for true wellness & lasting longevity

Everything came back normal.
You still feel terrible.

You're not imagining it. "Normal" has never meant optimal — and the space between the two is where you've been living. I find what's actually in that gap, and I stay with you while you close it.

Reachable, 7 days a week

Phone, text, email, or video. Same-day or next-day — not "the next available in three weeks."

Root cause, not symptoms

A complete thyroid picture instead of a lone TSH. Hormones, inflammation, insulin, nutrients.

Keep your insurance

I write your lab and imaging orders with diagnosis codes. You run them through your own plan.

One clinician. 100 members.

Not a care team. Not whoever's on rotation. Me — every call, every text, all year.

The gap nobody shows you

Your labs are "normal." But are they optimal?

TSH — thyroid stimulating hormone mIU / L
OPTIMAL · 0.3–2.5
0.31.02.54.5
Optimal range (0.3–2.5) Conventional “normal” (up to 4.5)
Same number. Two conclusions. Your result sits inside the conventional range, so you're told your thyroid is fine — and it sits well outside the range I'd actually want for you. It's one of the most common reasons a woman is told her thyroid is normal and still feels terrible. That gap is the entire conversation.

An illustration of a general pattern — not a diagnosis, and not a comment on your results.
Sound familiar

You've heard every one of these.

  • "Everything looks normal."
  • "It's probably just stress."
  • "This is normal for your age."
  • "Have you tried losing some weight?"
  • "Let's try you on something for the anxiety."
  • "I'll see you in six months."

Meanwhile you're exhausted in a way sleep doesn't fix. Foggy. Carrying weight that won't move. Sleeping badly. And you're being told — by someone with twelve minutes — that this is fine. It isn't fine. And it usually isn't mysterious either. Nobody has looked properly.

What you're actually paying for

A member texts me on a Sunday about a cough.

I'm on a call with her within minutes. She has her prescription within the hour.

That isn't an exceptional day. That's the standard. Same-day or next-day, by phone, text, email, or video — seven days a week. No portal. No triage. No waiting until Monday because it happened on a weekend.

Most practices sell you appointments. I sell the thing an appointment is a poor substitute for — a clinician who is actually reachable. That isn't a perk of the membership. That is the membership.

The part nobody expects

Keep your insurance. Use it.

I don't participate with insurance plans — that's exactly what buys us the time. But I hold a national NPI, which means the expensive part doesn't have to come out of your pocket.

  • I write your order, with the diagnosis codes on it. Bloodwork, X-ray, ultrasound, mammogram, CT, MRI — I can order all of it.
  • You take it to any LabCorp, Quest, BioReference, or imaging center your plan covers.
  • You run it through your insurance the way you would any other lab your doctor ordered.

Whether a given test is covered is between you and your plan — I can't promise that. But most of my patients run their labs through insurance and keep their coverage for hospitalizations and specialists.

You're not replacing your insurance. You're replacing the twelve-minute appointment.

How the work actually goes

Four steps, and none of them are rushed.

01

Your discovery call — $200

Forty-five to sixty minutes. Your goals, your full history, everything you've already tried, and the labs you already have — read against optimal ranges rather than conventional ones. We start shaping the plan on the call. If it isn't a fit, you still leave with answers, and there's nothing more to pay.

02

You join — then I order your workup

The $200 is credited and the remaining $1,000 completes your year. That's when the comprehensive workup goes out: advanced cardiovascular and inflammatory markers, insulin and metabolic health, a complete thyroid picture rather than a lone TSH, adrenal and sex hormones, and nutrient status. I write the order with codes; you run it through your insurance at LabCorp or Quest.

03

Your results review

Usually one to two weeks later. I walk you through every number — what it means, what needs correcting, and why. You leave with a written, personalized roadmap: nutrition, targeted supplements, bioidentical hormones where indicated, sleep, and stress.

04

The rest of your year

A check-in at one month, then as often as you need — text, call, email, video. Root- cause work is measured in months, not visits. That's exactly why this is a membership and not a series of appointments.

Honest filter

This works well for some people and badly for others.

This is for you if

  • You've been told your labs are normal and you don't feel remotely normal
  • You want to understand why — not just get something for the symptom
  • You're willing to test, follow a plan, and give it months rather than days
  • You want one clinician who knows your whole history
  • You're in Florida — visits are virtual, statewide

This isn't for you if

  • You're looking for a quick fix or one supplement that solves it
  • You want a protocol you found online written up and signed off
  • You want a coach rather than a licensed clinician
  • You need hands-on exams — this practice is entirely virtual
  • You're outside Florida — but the free guide below is for everyone
No surprises

What isn't included.

I'd rather you know now than find out later.

  • This is a 100% virtual practice. I don't offer in-person exams or visits. Anything needing a hands-on examination is better handled by urgent care or a local provider.
  • I don't participate with insurance plans. That means I can't provide insurance-required referrals or handle prior authorizations. If a specialist or test requires an in-network referral, you'd obtain that separately.
  • Labs and imaging aren't part of the membership. I order them and provide the codes — you run them through your own insurance.
  • Specialty functional testing is an additional cost. Challenged urine toxic metals, salivary adrenal panels, comprehensive stool analysis and similar tests aren't typically covered by insurance and are billed separately.
  • Supplements are separate. I'll tell you exactly what I'd want you on and why — you're never obligated to buy anything.

Most of my patients keep their regular health insurance for hospitalizations and specialists — and have me for everything else, seven days a week.

Start by reading your own labs properly.

A free 20-page preview of my Comprehensive Wellness Lab Guide: what the common markers actually measure, what conventional ranges miss, and what optimal looks like — for results you already have from your own physician.

Ten markers, normal vs. optimal, side by side.

Before you ask

The questions everyone asks first.

Can I really text you on a Sunday?

Yes. That's not a loophole in the membership — it's the point of it. Phone, text, email, or video, seven days a week. If something comes up on a weekend, you don't wait until Monday to be heard.

Do you take my insurance?

No, and that's deliberate. Insurance pays for coded visits and coded diagnoses — the system that produced your twelve-minute appointment and your "everything looks normal." Working outside it is what buys us the time. But your labs are a different story — see the next question.

So I have to pay for all those labs myself?

Usually not. I hold a national NPI, so I write your lab and imaging orders with the diagnosis codes on them, and you take them to any LabCorp, Quest, BioReference, or imaging center your plan covers. You run them through your insurance like any other lab. Whether a particular test is covered is between you and your plan — but this is the part most people assume they'll be paying cash for, and usually they aren't.

Does the $200 discovery call include my lab workup?

No. The discovery call is exactly that — a full clinical conversation where we work out what's likely going on and whether we're a good fit. The comprehensive workup is part of membership, and I order it once you've joined. That way nobody ends up half-way into a diagnostic process without the year of support behind it to actually act on the results.

Do I have to be in Florida?

For membership, yes — clinical licensure is state by state and I'm licensed in Florida. Visits are entirely virtual, so anywhere in the state works. The free lab guide and Lab Explorer are available to anyone, anywhere.

Can I keep my regular doctor?

Most of my patients do, and I'd encourage it. Keep your insurance and your local providers for hospitalizations, specialists, and anything needing a hands-on exam. I'm the one you call for everything else — and the one actually looking for the cause.

Can I split the payment?

Yes. If the balance is easier over three or four months, just ask — I'll set it up at no extra cost.

What if I already have labs?

Bring them. Most people arrive with more data than they realize — it just hasn't been read against optimal ranges. Reviewing what you already have is part of the discovery call.

How quickly will I feel better?

I won't promise you a timeline, because anyone who does is guessing. Root-cause work is measured in months. What I will promise is that you'll understand what's happening and why — and you'll never be waiting three weeks for an answer.

You've already spent years being told you're fine.

Forty-five minutes, and you'll understand more about what's driving this than you have in the last five appointments combined.
