Pine Park Health
A primary care practice that puts clinicians inside senior living communities instead of asking residents to travel out. It raised $44 million, reached roughly 200 buildings in three states, and built its value based business on Medicare Advantage contracts, not the CMS models it once said it had joined.
The urinalysis that never leaves the building
A resident of a California assisted living community starts showing the signs of a urinary tract infection. In most of American senior living that begins a sequence: a call to the family, a call to a doctor who cannot come, then an ambulance and a night in an emergency department that leaves the patient more confused than when she arrived.
Pine Park Health built its practice around deleting that sequence. Its clinicians keep a small supply room inside the community, and the equipment in it includes a urinalysis kit. The test runs on site. If it is positive, the antibiotic is prescribed on the spot.
“We’re not waiting for specimens to go out to a lab and come back two days later,” Dan O’Neill, the company’s chief commercial officer, told Senior Housing News in 2022.
That is the proposition, compressed. Everything else follows: who pays, how fast it can grow, and which parts of the record hold up.
The problem it is aimed at
Roughly 2.8 million people in the United States live in senior housing, according to a 2022 essay by the venture firm NEA, which helped assemble the competing group Curana Health. NEA counted an estimated 27 million more people aging into the 75 and over cohort through 2050.
Those residents are among the most expensive patients in Medicare, and the reason is as much logistical as clinical. A frail 85 year old with six prescriptions and early dementia does not stop needing care because her doctor is 12 miles away. She gets it later, in a worse setting, at a higher price. The fix is not a drug or a device but a delivery change, and delivery changes survive only if somebody pays differently for them. Hence the company’s framing: “We believe healthcare providers should be paid to help patients get or stay healthy,” the about page reads.
A founder who moved in
The company traces to George Khasin, co-founder and chief executive, who had been working on remote monitoring for senior living. To understand the setting he lived in a community for a period. What he found was not a monitoring gap. “He really came to it organically, living in a community and seeing for himself what was missing,” O’Neill said. Khasin’s co-founder is not named in the public sources reviewed here.
O’Neill joined in April 2021 and matters more than a commercial title usually does. He was a Robert Wood Johnson Foundation health policy fellow at the National Academy of Medicine, worked in the US Senate on surprise billing and price transparency, and was a senior vice president at Change Healthcare. He owns the payer contracts that make the clinical model solvent. The chief medical officer is Payam Parvinchiha, MD, MPH.
The clinical design is worth stating precisely. Pine Park’s primary care providers are board certified nurse practitioners and physician associates. Physicians serve as medical directors who oversee a set of communities and take the complex cases.
Fifty buildings to two hundred
In January 2022 the practice was in about 50 communities, mostly in northern California. By September 2022 it was past 80, across nine counties in California and Arizona. That December it bought Geriatric Specialty Care of Nevada, a practice CMS records show has been enrolled in Medicare since 2009, and reported more than 120 locations in three states. By April 2024 the company said it ran more than 150 communities, and a 2026 vendor case study describes nearly 200. It also moved into affordable senior housing with HumanGood and Eden Housing, where residents are poorer and buildings thinner on staff.
What is proven, and what is still claimed
| Evidence | What the record shows | Source type |
|---|---|---|
| Medicare enrollment | Organizational NPI 1346879848, PECOS id 0345670527, a Part B supplier, clinic or group practice. The July 17, 2026 CMS extract carries two enrollments, California and Arizona. No Nevada record appears under the Pine Park name. | Public record |
| ACO REACH and Direct Contracting | Absent from the CMS ACO REACH Providers public use files for PY2021 through PY2024, which name every participant provider by legal business name, and from the ACO level lists for PY2023 through PY2026. | Public record |
| Medicare Shared Savings Program | No match in the CMS participant or ACO organization files for PY2022 through PY2026. Curana Health and Sound Physicians entities do appear there. | Public record |
| Company statement on CMS models | A March 2022 podcast biography said O’Neill is “responsible for risk-based contracting with IPAs and insurers and for the group’s participation in CMS value-based care models, including direct contracting.” CMS participant provider files for those years do not list the company. | Differs from the record |
| Where the value based revenue comes from | In 2022 the company said “Today, Pine Park participates in traditional Medicare and is in-network for all major Medicare Advantage insurers in California.” In 2025 SCAN Health Plan told STAT that Pine Park is subcontracted with its at-risk provider groups. The insurance page lists in-network plans across ten California counties and three counties in Arizona and Nevada. | Company-stated |
| Named operator partners | HumanGood, Senior Resource Group, Westmont Living, Brookdale, Pacific Retirement Services, Eden Housing. HumanGood dates the relationship to 2021 at two life plan communities and to July 2022 in affordable housing. | Partner-stated |
| Acquisition | Geriatric Specialty Care of Nevada, December 2022. CMS still carries the entity as a Nevada Part B clinic or group practice, NPI 1205088838, enrolled in 2009. | Public record |
| Risk adjustment analytics | In April 2024 the company said it would use Innovaccer analytics to “improve the accuracy of patients’ RAF scores.” Risk adjustment coding is the most scrutinized area of Medicare Advantage economics. No enforcement action or allegation involving Pine Park Health was found in the public record searched here. | Company-stated |
| Operating results | About 2.1 full time equivalents of medical assistant time returned and a 55.7% booking rate for an outbound AI scheduling agent, per a vendor case study and a June 2026 trade article. | Company-stated |
| Published outcomes | No hospitalization, cost or quality results attributable to Pine Park found in the literature, CMS evaluations or independent reporting. | Not found |
Read plainly: the delivery model is real, the footprint is real, and the enrollment record confirms a working Part B group practice. What is missing is the number the whole value based argument rests on. Nobody outside the company has published evidence that Pine Park patients go to the hospital less or cost Medicare less. The company also sits one layer below the entities carrying formal risk. That is a workable business, and a different thing from holding a CMS accountable care agreement in its own name.
What to watch
- Any published outcome data. One credible hospitalization or total cost of care result would move this company from plausible to proven.
- Whether Pine Park ever appears in a CMS participant file. ACO REACH ends after 2026, so the near term route into CMS risk is the Shared Savings Program.
- Whether the network access problems described in the August 2025 STAT essay ease, since they cap entry into any new market.
