SPMD Is Not Medical Care
SPMD assesses performance. SPMD does not assess health.
That distinction is the entire page. Everything below explains it.
What does SPMD do?
SPMD applies clinical method to performance.
The SPMD Leak Assessment measures where performance is leaking across five domains. The Fundamentals Toolkit, the Performance Protocol, and Precision Coaching teach a person to name the leak, match an intervention to it, and execute.
That is education and coaching. It is not care.
What does SPMD not do?
SPMD does not diagnose disease. SPMD does not treat illness.
SPMD does not prescribe, order or interpret tests, manage medication, or provide psychotherapy. SPMD does not evaluate whether you are sick.
SPMD does not replace your physician, your therapist, your psychiatrist, or any other clinician. If you need one and do not have one, get one. Nothing here substitutes for that.
Why does SPMD use clinical language?
Because the method is clinical. The relationship is not.
Physicians are trained to assess before intervening, to match the intervention to the mechanism, and to say plainly when the evidence is weak. That discipline is what the performance industry mostly lacks. Importing it is the entire point of SPMD.
So SPMD uses words like assess, diagnose, indicated, and matched. Those words describe how the method works. They do not describe a medical practice, and they do not make you a patient.
When SPMD says diagnose, it means one thing: identify which performance leak is loudest. It does not mean identify a disease.
When SPMD names a DRAINS, that is a performance state. It is not a medical condition, it is not a psychiatric condition, and it does not appear in any diagnostic manual. Spent is not a diagnosis of anything. Nerve Failure is not a neurological finding. These are performance vocabulary, and they are deliberately not clinical terms.
Does using SPMD make Will King-Lewis your doctor?
No.
Will King-Lewis is a licensed physician, board certified in Family Medicine. SPMD does not hide that. It is the reason SPMD exists.
But holding a medical license does not mean every interaction creates a physician-patient relationship, and no SPMD product creates one.
Taking the Assessment does not make you a patient. Buying the Fundamentals Toolkit or the Performance Protocol does not make you a patient. A Precision Coaching engagement does not make you a patient, and the coaching contract states so directly, because a fiduciary documents the relationship.
No physician-patient relationship is formed through this website, the Assessment, any email, any product, or any coaching session. No medical record is created. Nothing you share with SPMD is protected the way a medical record is protected. Do not send SPMD information you would only want a treating physician to hold.
What if something is actually wrong?
Then SPMD is the wrong tool, and SPMD is built to say so.
A performance instrument cannot tell an exhausted person from a sick one. That is not a flaw in the instrument. It is the limit of what any thirty-three-question survey can do, and pretending otherwise would be the exact failure this brand exists to argue against.
When the Assessment returns severe multi-domain impairment, it stops selling. That path returns no product, no offer, and no reward. It returns crisis resources and a direct email address, and it does that in every message it sends.
If you are in crisis in the United States, call or text 988. If this is an emergency, call 911 or go to an emergency department.
Do not use a performance assessment to decide whether you are sick. It cannot answer that question. It was never built to.
What about the clinical claims on this site?
They are labeled, and they are general.
SPMD labels every mechanism as validated, clinically reasoned, mixed evidence, or evidence question open. Those labels are the honest state of the science rather than marketing. Where the evidence does not settle a question, SPMD says so and leaves it unsettled.
None of it is medical advice for you specifically. General education about sleep, training, or cognition is not a clinical recommendation, because a recommendation requires knowing the person receiving it. SPMD does not know you.
Before you change medication, start an exercise program, alter your diet, or act on anything you read here in a way that touches your health, talk to your own clinician.
