States associated
Practice-location states
- MACurrent location
License-only states
- RILicense only
"License only" means Phoenix found licensing evidence in that state but no practice-location evidence. A license does not mean the provider practiced there, and practicing without a listed license is possible (telehealth, locums, federal facilities). Where the relationship cannot be determined, Phoenix shows nothing rather than guessing.

State boards are the authoritative record for licensure and any public action. Phoenix does not summarize board findings. The absence of a record here is not evidence of a clean record.

Phoenix Insight™
Why Practice Location Matters
Where care happens affects travel, scheduling, caregiver support, and follow-up visits.
Ongoing care often means several visits. A location that is realistic for you — by car, transit, or with a caregiver — makes it easier to keep appointments and follow through on treatment.
Addresses shown here come from the provider's registered public records.
What this does not tell you
- — Registered addresses can be billing offices rather than places you can visit.
- — Providers may practice at locations that are not in public records.
- — Call ahead to confirm the address, hours, and accessibility.
Educational information only — not medical advice, and not a rating or endorsement of any provider.

Phoenix Insight™
How to Read Years Licensed
Years licensed shows how long a provider has held an active professional license, based on public licensing records.
This number is calculated from the earliest license issue date Phoenix can confirm in public records. It gives you a sense of how long someone has been practicing under a license.
Some people prefer a provider with long experience; others prefer a provider trained more recently. Both are reasonable preferences.
What this does not tell you
- — Longer does not mean better, and newer does not mean worse.
- — Records can be incomplete — a provider may have been licensed earlier in a state Phoenix has not yet confirmed.
- — This information is not a rating, ranking, or endorsement, and no single data point should decide your care.
Educational information only — not medical advice, and not a rating or endorsement of any provider.

Where Phoenix Gets Its Information
Phoenix Health Compass builds profiles from official government and licensing sources, and links to every one of them.
Knowing where information comes from helps you judge how much weight to give it. Phoenix prioritizes federal registries, state licensing boards, and other official public datasets.
Every data element on a profile carries a source link so you can confirm it yourself at the original agency.
What this does not tell you
- — Public sources are not complete, and coverage differs by state and profession.
- — Phoenix does not add opinions, ratings, or private information to these records.
Learn more from trusted public sources
- NPPES NPI Registry — The federal registry of provider identity, specialty taxonomy, and practice address.
- CMS Data — Federal enrollment, participation, and quality datasets.
- OIG Exclusions Database — Federal exclusion records for healthcare programs.
