MD / DO
BaselineLicensed physician
A state medical license is the floor, not a distinction. Every provider in the registry is required to name the licensed physician who carries clinical responsibility for the program.
Doctors
There is no board certification in longevity medicine.
Anyone with a medical license may open a longevity practice in the United States. That is why the letters after a physician's name matter — and why some of them carry far less than they appear to. This page explains what each credential is, who issues it and what it does not prove.
Credential glossary
Six things you will see on a clinic's team page
ABMS
StrongBoard certification in a primary specialty
Certification by an American Board of Medical Specialties member board — internal medicine, family medicine, cardiology, endocrinology — means supervised residency training and periodic recertification. There is no ABMS board for longevity medicine.
Fellowship
StrongAcademic subspecialty training
Two to three years of accredited training after residency, in geriatrics, endocrinology, sports medicine or preventive medicine. The closest thing to formal training in the mechanisms longevity clinics work with.
ABAARM / ABAAHP
ContextAnti-aging and regenerative medicine boards
Issued by the American Academy of Anti-Aging Medicine, not by ABMS. It documents dedicated coursework and an examination in hormone, metabolic and preventive protocols. Read it as a declared focus, not as an equivalent to specialty certification.
IFM
ContextInstitute for Functional Medicine certification
A structured curriculum in functional medicine with case submissions. It signals a methodological orientation. It says nothing about how conservatively a clinician prescribes.
Affiliation
StrongHospital or university appointment
An active appointment at an academic medical center means the clinician's practice sits inside institutional oversight — credentialing committees, peer review, malpractice structures. It is the most underrated signal on a clinic's team page.
Due diligence
Five questions before a first consultation
01
Who is clinically responsible for my protocol?
Ask for a named physician, their primary board certification and their state of licensure. If the answer is a brand, a coach or an unnamed medical director, treat that as the answer.
02
What happens to a finding you cannot treat?
A serious incidental finding on a whole-body scan or a cancer-detection test needs a referral pathway into specialty care. Ask which hospital or specialists receive those referrals.
03
Which of your therapies are off-label or investigational?
Peptides, NAD+ infusions and several hormone protocols are prescribed off-label in the United States. A clinician who names that plainly is easier to trust than one who does not raise it.
04
How is the physician compensated?
Ask whether prescribing, supplement sales or infusion volume affect the clinician's income. Membership-only pricing and dispensary revenue create different incentives.
05
What is my exit?
Ask how a program ends: what you keep, whether records transfer to your primary care physician in a usable format, and what stops if you stop paying.
Institutional oversight
Hospital and university programs in the registry
If credentialing and referral pathways are your priority, start with the programs that sit inside an academic medical center.
