The map nobody handed you.
Arizona Nephrology Practices, Vetted and Independent
154 nephrology groups in Arizona that physicians still own. No hospital systems, no private equity, no academic posts. Just the map nobody else built.
Pre-med was a checklist. Med school was a checklist. Residency interviews were a checklist. Boards were a checklist. Even the Match algorithm was a checklist someone else wrote.
Most nephrology physicians sign their first contract without knowing how many other groups exist within driving distance. This is the single largest source of leverage you give away in your career, and you give it away because nobody told you the information was out there. The Real Contract course walks you through every clause that matters.

About this directory and the Arizona nephrology market
PGY-Final-Year is the first time the path is not drawn for you.
Then your final year starts and the path stops drawing itself. Recruiters start emailing. Contracts show up before you have asked anyone what a contract is supposed to look like.
The senior residents signed their first contracts without reading every clause. Not because they did not care, but because nobody had handed them a map of what else existed. So they took the first offer. This directory exists so you do not have to.
What other resources point to in Arizona
You're looking at 90 physician-owned nephrology practices in Arizona. I sourced all of them from the NPPES NPI Registry and filtered out everything that doesn't meet the standard of independent physician ownership. Hospital systems, academic centers, staffing agencies, and corporate-acquired practices are not on this list. Each entry includes the practice address, phone, website, and NPI number. The coverage spans 23 cities statewide.
I made this because the information doesn't exist in one place anywhere else. If you're a nephrology physician thinking about Arizona, you'd normally have to search job boards, call recruiters, and piece together which practices are actually physician-owned versus corporate-backed. This page does that work for you. 90 practices, 23 cities, all verified through the NPPES NPI Registry. Contact them directly.
The Arizona nephrology market in detail
Arizona's physician-owned nephrology directory lists 90 practice locations across 15 cities. The largest groups include Southwest Kidney Institute, PLC (16 locations), Southwest Kidney Institute (7 locations), and Arizona Kidney Disease and Hypertension Centers (4 locations).
None of the nephrology practices listed in Arizona carry a PE-Backed or Corporate-Acquired flag. All listings in this directory are physician-owned independent practices verified through NPPES.
Practices span 15 cities including Benson, Chandler, Flagstaff, and Glendale.

Frequently asked questions about nephrology in Arizona
How many Nephrology private practices are in Arizona?
There are 90 physician-owned nephrology private practices in Arizona, verified against the NPPES NPI Registry. All are independently operated. Hospital-employed, government, corporate, and academic positions are excluded.
What does physician-owned mean?
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.
What does the Corporate-Acquired or MSO-Affiliated flag mean?
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.
Dialysis Clinic Ownership in Arizona Nephrology
Arizona's physician-owned nephrology practices include Arizona Kidney Disease and Hypertension Center (Phoenix, 80 physicians), Southwest Kidney Institute (Tempe, 50 physicians), Tucson Nephrology (Tucson, 6 physicians), and Northern Arizona Nephrology (Flagstaff).
What is an NPPES-verified practice?
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.
Is dialysis clinic ownership still possible for nephrologists in private practice in Arizona?
Yes, but it is increasingly difficult. Roughly 80% of U.S. dialysis facilities are controlled by DaVita or Fresenius. Independent or joint-venture physician ownership still exists in Arizona in some markets, particularly smaller communities where the national dialysis organizations have less penetration. CMS certification, ESRD Network participation, and CON requirements (if applicable in Arizona) must all be navigated. Physician-owned dialysis revenue historically represented 30-50% of total nephrologist income in practice settings that had it.

Key Terms in Physician Contracts
PLLC (Professional Limited Liability Company)
A hybrid entity combining LLC flexibility with professional licensing requirements. PLLCs are common for physician-owned practices in states that permit them. They offer pass-through taxation and personal liability protection for non-malpractice claims.
MSO (Management Services Organization)
A non-physician entity that provides administrative infrastructure (billing, coding, EHR support, payer contracting) to physician-owned practices. MSO arrangements let physicians retain clinical and practice ownership while outsourcing back-office operations. Private equity commonly uses MSO structures to influence practice operations without technically owning the medical entity.
NPI (National Provider Identifier)
A unique 10-digit number assigned to every U.S. healthcare provider and organization by CMS. Individual physicians receive a Type 1 NPI; practice entities receive a Type 2 NPI. The NPI is used across all payers for billing and credentialing.
Restrictive Covenant
Any contractual clause that limits a physician's professional activities after leaving an employer. Non-compete clauses are the most common restrictive covenant, but the category also includes non-solicitation clauses (prohibiting contact with former patients or staff) and non-disparagement clauses.
Fair Market Value
The price at which a willing buyer and willing seller would agree to transact, with both parties having reasonable knowledge of the relevant facts. Physician compensation must meet fair market value to comply with federal anti-kickback and Stark Law requirements. Independent valuations are used for buy-in pricing, compensation benchmarking, and practice sales.
ESRD (End-Stage Renal Disease)
Permanent kidney failure requiring dialysis or transplantation. ESRD patients are automatically enrolled in Medicare regardless of age. Medicare reimburses dialysis at a bundled rate per treatment (approximately $240-$250 per session) under the ESRD Prospective Payment System.
CON (Certificate of Need)
A state regulatory requirement that healthcare providers obtain government approval before adding certain types of healthcare facilities or services. Not all states have CON programs; those that do may require CON approval for new dialysis facilities, affecting the feasibility of independent dialysis ownership.
