There are 52 physician-owned hematology & oncology practices in Maine, vetted against the NPPES NPI Registry. Hospital-employed, government, and academic positions are excluded.
68 independent hematology & oncology practices across Maine, cross-referenced against NPPES, state medical boards, and each practice's own website. Negotiate from leverage instead of from gratitude.
You spent 15 years on a path where the next move was always obvious. Someone handed you a syllabus, an algorithm, a board study schedule, a rotation block. You executed.
The difference between a physician who has read this directory and one who has not is the difference between negotiating from options and negotiating from desperation. Same skills, same training, same offer letter. Different leverage. 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 PGY-Final arrives. Suddenly there is no syllabus, no advisor telling you which clause to push back on, no upperclassman who has done this before. There is only a contract and a clock.
What this directory does is hand you the page you were missing. Every physician-owned hematology & oncology group in Maine, in one place, so the first contract you sign is not the only contract you ever saw.
What you'll find here is a complete list of 52 physician-owned hematology & oncology practices in Maine, verified against the NPPES NPI Registry. I started with the full federal database and worked backwards, removing every practice that doesn't qualify as independently operated. No hospital jobs. No PE-backed groups. No staffing agencies. Just 68 practices across 16 cities where physicians own the entity and control the clinical direction.
Here's why I built this. When I was looking at private practice opportunities, I couldn't find a single resource that separated physician-owned practices from everything else. Job boards don't do it. Recruiter databases don't do it. So I built it from the NPPES registry. Whether you're finishing training, thinking about a lateral move, or exploring partnership-track positions in Maine, this gives you a filtered starting point that actually tells you who owns what.
Maine's physician-owned hematology & oncology directory lists 52 practice locations across 14 cities. The largest groups include Northern Light Cancer Care (3 locations), Chiara Battelli, MD (2 locations), and Nicholette Erickson, MD (2 locations).
None of the hematology & oncology 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 span 14 cities including Augusta, Bangor, Bath, and Brewer.
The Directory is step one. The course teaches you what the contract actually says. The lawyer makes sure you sign the right one.
You are already here. 52 physician-owned hematology & oncology groups in Maine, vetted against NPPES.
The Real Contract walks you through every clause that matters: non-compete, productivity, tail coverage, partnership track.
A vetted directory of physician-contract attorneys in Maine. The person on your side should be one who actually does this work.
It starts with this page. Then the course. Then the right lawyer. The order matters.
“The map did not run out for you. It ran out for everyone in your year.”
Daniel Aragón, MD, MBAThere are 52 physician-owned hematology & oncology 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's only physician-owned hematology & oncology practice in this directory is New England Cancer Specialists in Portland (founded 1978).
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.
In the buy-and-bill model, the oncology practice purchases chemotherapy drugs from a distributor (often through a Group Purchasing Organization for better pricing) and then bills payers for drug administration at the payer's contracted rate. Under Medicare Part B, reimbursement is typically at ASP (average sales price) + 6%. The spread between acquisition cost and reimbursement rate is the drug margin. Practices with favorable GPO contracts and a high commercial payer mix generate substantial drug margin revenue that does not exist in hospital-employed oncology.
| Physician-Owned | Hospital-Employed | Corporate / PE-Backed | |
|---|---|---|---|
| Who controls the practice | Physicians | Health system | Non-physician entity |
| Non-compete scope | Narrower, negotiable | Broad | Very broad |
| Partnership / buy-in path | Common | Rare | Rare |
| Call schedule flexibility | Higher | Variable | Lower |
| Productivity bonus upside | High | Moderate | Moderate |
| Included in this directory | Yes | No | Flagged |
