Entrepreneurial Members. One Alliance.
Personalized.Proactive.Preventative.Private.
The four pillars of how our members practice medicine.
A national alliance of physician-led concierge, DPC, and hybrid practices
The Private Physicians Alliance enables entrepreneurial practices to achieve the purchasing power and operational scale of a national health system, while preserving owner-led autonomy.
What the alliance
stands for.
The following Principles define who PPA is, what it stands for, and the lens through which all membership, conduct, and strategic decisions are made.
Ratified July 2026
Give to Get
Members contribute knowledge, experience, and referrals freely, trusting that the network reciprocates. This is the engine of PPA’s value.
Physician Independence
PPA exists to support physicians who lead their own clinical decisions, free from investor-driven pressure on patient care.
Community & Camaraderie
The relationships built through PPA are as valuable as the clinical resources. Culture and trust are what make this community worth belonging to.
Patient First, Patient-Centered Care
PPA exists to advance the movement of personalized, preventive healthcare — bringing this model of care from a niche offering to a mainstream reality.
Knowledge, Transparency & Shared Values
PPA is the neutral conduit for honest, peer-driven information sharing. We do not put our heads in the sand. Members deserve unfiltered access to the real experiences of their peers.
Infrastructure for
Autonomy.
We don't sell transactions. We provide the operational chassis for high-growth private practices.
Market Intelligence
Proprietary benchmarking on payer rates, coding audits, and regional reimbursement trends. Know exactly what your peers are getting paid.
02The Afternoon Report
Monthly virtual briefings with clinical, operational, or legal experts. Live attendance earns CME credit; the full archive lives on the PPA App as summaries and video.
03Exclusive Member Offers
Negotiated rates and special offers with curated industry partners on supplies, equipment, technology, and professional services. Not every EMO is a discount, some are exclusive access to services or vendor relationships members can’t get on their own.
04The Peer Network
Direct access to fellow physician-led owners and operations leaders. Forums, referrals, vendor recommendations, and operational know-how from people running practices like yours.
