About this directory and the Oregon pulmonary disease market
You finished pulmonary disease. Now what?
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.
Before you compare salary numbers, see how many physician-owned groups actually exist in your specialty and state. Then negotiate from leverage instead of from gratitude.
What other resources point to in Oregon
You're looking at 75 physician-owned pulmonary disease practices in Oregon. 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 14 cities statewide.
Most physicians looking for pulmonary disease opportunities in Oregon start with a recruiter or a job board. Both of those sources mix hospital-employed roles with genuine private practice opportunities, and they rarely disclose ownership structure upfront. This page does one thing differently: it filters for physician ownership using the federal NPPES registry. That's it. The result is 75 practices you can contact directly, without a middleman deciding what you're allowed to see.
The Oregon pulmonary disease market in detail
Oregon's physician-owned pulmonary disease directory lists 75 practice locations across 13 cities. The largest groups include Hataya Kristy Poonyagariyagorn, MD (3 locations), Deepti Singhvi, MD (2 locations), and Jennifer Hines, DO (2 locations).
None of the pulmonary disease practices listed in Oregon carry a PE-Backed or Corporate-Acquired flag. All listings in this directory are physician-owned independent practices verified through NPPES.

Frequently asked questions about pulmonary disease in Oregon
How many Pulmonary Disease private practices are in Oregon?
There are 75 physician-owned pulmonary disease private practices in Oregon, 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.
Pulmonary Function Lab Ownership in Oregon Pulmonology
Oregon has 5 physician-owned pulmonary disease practices in this directory, including The Oregon Clinic - Pulmonary, Critical Care, and Sleep Medicine (Portland), Northwest Pulmonary and Sleep Specialists (Portland), and The Portland Clinic - Pulmonary Disease (Portland). Summit ...
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.
How does pulmonary function lab ownership affect compensation in private pulmonology practices in Oregon?
When a pulmonology practice owns its PFT equipment and employs its own respiratory therapist to perform testing, the practice bills and collects the technical component of PFT studies (spirometry, DLCO, plethysmography) separately from the physician's interpretation fee. This technical component revenue, which would otherwise go to a hospital if testing were referred out, can add $100,000-$300,000+ annually to a high-volume pulmonology practice's revenue. Ask for the annual PFT testing volume and what portion of technical component revenue is distributed to physician-owners.

Key Terms in Physician Contracts
PC (Professional Corporation)
A state-chartered corporation formed by licensed professionals. Physicians use PCs to own and operate their practices with liability separation. Many states require medical practices to be structured as PCs rather than standard LLCs or general partnerships.
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.
Pulmonary Function Testing (PFT)
A battery of breathing tests that measure lung volumes, airflow, and gas exchange. Includes spirometry (CPT 94010), diffusion capacity/DLCO (CPT 94729), and plethysmography (CPT 94726). Each test has separate professional (physician interpretation) and technical (equipment, technician) billing components.
DLCO (Diffusion Capacity of the Lung for Carbon Monoxide)
A pulmonary function test measuring the efficiency of gas exchange across the alveolar-capillary membrane. Reduced in interstitial lung disease, emphysema, and pulmonary vascular disease. Billed separately from spirometry with both professional and technical components.
