There are 16 physician-owned endocrinology practices in Maine, vetted against the NPPES NPI Registry. Hospital-employed, government, and academic positions are excluded.
A vetted list of 22 endocrinology practices in Maine that are still owned by the physicians who built them. Useful when the recruiter says you have no other options.
For 15 years the path was visible. Pre-clinical, clinical, sub-I, Match, intern year, residency, fellowship. Every transition had a name and a date.
If a recruiter tells you the hospital is the only viable endocrinology employer within driving distance, you should be able to name five physician-owned groups that prove otherwise before the end of the call. This directory is how you get to five. The Real Contract course walks you through every clause that matters.
Hospital-employed, government-operated, and academic positions are excluded. These are not independent private practices:

Then training ends and the page goes blank. The first contract lands in your inbox with terms you have never seen, written by people who do this for a living against someone who has done it exactly never.
Nobody is telling you what other endocrinology practices exist in Maine, what the contract really says, or which lawyer to call. The senior people in your program signed without reading because they had no guide either. This directory is the first page of the map.
I built this directory by starting with the NPPES NPI Registry, the federal database where every medical practice in the country has to register. From there, I filtered Maine's endocrinology listings down to practices that are genuinely physician-owned. That means no hospital-employed roles, no academic faculty positions, no corporate-acquired clinics. What you're looking at is 22 independent endocrinology practices across 10 cities in Maine.
The reason this matters is that job boards don't distinguish between an independent endocrinology practice and a corporate medical group. They list them side by side, identical formatting, identical apply buttons. But the compensation model, the call schedule, the equity path, and the long-term upside are completely different depending on who owns the practice. This page separates the two. You can work through the list, contact practices directly, and skip the recruiter entirely.
Maine's physician-owned endocrinology directory lists 16 practice locations across 6 cities. The largest groups are Northern Light Endocrinology and Diabetes Care (3 locations) and Northern Light Diabetes and Nutrition (3 locations).
None of the endocrinology practices listed in Maine carry a PE-Backed or Corporate-Acquired flag. All listings in this directory are physician-owned independent practices verified through NPPES.
Practices are located in Bangor, Blue Hill, Lewiston, Portland, Scarborough, and South Portland.
Browsing 53,000+ practices is not the work. Translating that into a contract you understand and a lawyer who will read it with you is the work. Here is how.
You are already here. 16 physician-owned endocrinology groups in Maine, vetted against NPPES.

“The map did not run out for you. It ran out for everyone in your year.”
Daniel Aragón, MD, MBAThere are 16 physician-owned endocrinology private practices in Maine, verified against the NPPES NPI Registry. All are independently operated. Hospital-employed, government, corporate, and academic positions are excluded.
A physician-owned practice is one where licensed physicians hold controlling ownership of the business entity. This is distinct from hospital employment, corporate medical groups, or private equity-backed practices where non-physician entities control the business.
The Corporate-Acquired flag means the practice was historically physician-owned but has since been acquired by a corporate entity such as Optum. The MSO-Affiliated flag means the practice uses a Management Services Organization for billing and administration while physicians retain practice-level ownership.
Maine doesn't have physician-owned independent endocrinology practices in this directory. Most endocrinology positions are hospital-employed or part of larger health systems.
NPPES is the National Plan and Provider Enumeration System, a federal database maintained by CMS. Every practice in this directory has an active NPI record in NPPES, confirming it is a registered U.S. medical practice.
Private endocrinology practices in Maine commonly add: DEXA scanning for osteoporosis (technical component revenue), in-house laboratory services (HbA1c, thyroid, metabolic panels with a CLIA-certified lab license), continuous glucose monitor (CGM) supply dispensing, and DSMES (Diabetes Self-Management Education and Support) programs. Each adds revenue beyond E&M billing without requiring new physician FTEs. Ask any prospective practice which of these services are active and how the revenue is distributed.
