Licensing and certification boards are the authority on a doctor's credentials. If a link on this page has moved, search for the board by name rather than relying on third-party review sites.
Two separate checks
A license and a board certification answer different questions. The license shows the doctor is allowed to practice medicine in Arizona. Board certification shows they have been certified by a specialty board in a field such as endocrinology. Look for both, because one does not imply the other.
Step 1: Check the Arizona license
Arizona has two licensing boards for physicians. Which one you search depends on the doctor's degree:
| Degree | Licensing board | Website |
|---|---|---|
| MD | Arizona Medical Board | azmd.gov |
| DO | Arizona Board of Osteopathic Examiners | azdo.gov |
Look up the doctor at the Arizona Medical Board if they are an MD, or at the Arizona Board of Osteopathic Examiners if they are a DO. The degree tells you which board to search; it doesn't tell you the specialty. Match the full name, including any middle initial, and confirm the license shows as active.
Step 2: Check board certification in endocrinology
Adult endocrinologists are generally certified in internal medicine and then in the subspecialty of Endocrinology, Diabetes and Metabolism, both through the American Board of Internal Medicine (ABIM). ABIM's site offers a Verify a Physician tool. Internal medicine certification on its own describes an internist, not an endocrinologist; the Endocrinology, Diabetes and Metabolism listing is the one to look for.
Children's endocrinologists are certified through the American Board of Pediatrics. The ABMS Certification Matters site is another public lookup for board certification.
| Patients | Certifying board | Certification to look for |
|---|---|---|
| Adults | American Board of Internal Medicine | Endocrinology, Diabetes and Metabolism |
| Children | American Board of Pediatrics | Pediatric endocrinology |
What a fellowship means
Endocrinologists complete specialty training called a fellowship after their general residency. Three Valley programs show what that looks like:
- The University of Arizona College of Medicine – Phoenix runs a two-year, ACGME-accredited Endocrinology, Diabetes and Metabolism Fellowship, with training at sites including the Phoenix VA and Banner – University Medical Center Phoenix.
- Mayo Clinic runs a two-year endocrinology fellowship in Phoenix/Scottsdale, which accepted its first fellow in July 2022.
- Phoenix Children's runs a pediatric endocrinology and diabetes fellowship.
You can read about each program on the UA College of Medicine – Phoenix, Mayo Clinic and Phoenix Children's sites. At a teaching hospital you may meet a fellow who is still in training. That is a normal part of academic care, and you can ask who the supervising endocrinologist is.
Where to find a doctor's specialty and training
Hospital and university profile pages often list a doctor's specialty by its board name. On HonorHealth's site, for example, this physician profile lists the specialty as Endocrinology, Diabetes and Metabolism. The UA College of Medicine – Phoenix publishes a faculty page, and Mayo Clinic publishes physician biographies such as this one. We link these only as examples of where to look, not as recommendations. Use profiles as a starting point, then confirm with the board lookups.
Spotting endocrinology-sounding marketing
Titles like diabetes specialist, hormone doctor or thyroid expert are marketing language, not board certifications. Some clinics that use them are led by endocrinologists; others are not. Before you book, especially if your referral says endocrinology, run through this checklist:
- Is the person you'll see a physician (MD or DO) with an active Arizona license?
- Do the ABIM, American Board of Pediatrics or ABMS lookups show certification in endocrinology, not only internal medicine or pediatrics?
- Does the clinic name the specific doctor you'll see, or only a brand?
- Does the doctor's profile list the specialty by its board name, such as Endocrinology, Diabetes and Metabolism?
- Does your insurance treat the visit as an endocrinology specialist visit? Ask your plan if you're unsure.
Clinics often employ a mix of clinicians, which can be appropriate for some care. If your referral is specifically for an endocrinologist, ask the office who will see you and confirm that person's credentials yourself.
If something doesn't match
If a name doesn't come up, check the spelling, try the other licensing board, or ask the office for the doctor's full name and degree. If you still can't find the license or certification, raise it with the office or your referring doctor before the appointment. For booking and paperwork, see our referrals and insurance guide and the hospital programs guide.
Frequently asked questions
How do I check if a doctor is licensed in Arizona?
Search the Arizona Medical Board (azmd.gov) for MDs or the Arizona Board of Osteopathic Examiners (azdo.gov) for DOs, and confirm the license is active.
What does board certified in endocrinology mean?
For adult doctors, it means certification by the American Board of Internal Medicine in the subspecialty of Endocrinology, Diabetes and Metabolism. Internal medicine certification alone is not the same thing.
How can I check a pediatric endocrinologist?
Check the Arizona license with the right board, then look for pediatric endocrinology certification from the American Board of Pediatrics or through the ABMS Certification Matters lookup.
How long is endocrinology fellowship training?
The local adult programs at the UA College of Medicine – Phoenix and Mayo Clinic in Arizona are both two-year fellowships.
Is a hormone doctor the same as an endocrinologist?
Not necessarily. It's a marketing term, not a board certification. Use the license and certification lookups to see what training the clinician has.
Does this site verify doctors for me?
No. We explain how to use the public tools. We don't certify, rank or recommend individual doctors.
