Time, finally.
Your physician carries a panel of 320 patients — a quarter of the panel size in fee-for-service primary care. Visits are 60 minutes. Annual physicals are 90. There is enough time, by design.

Primary care without the system.
Atrium is a private medical practice for individuals and families who want a real relationship with their physician. Closed-record, fee-only, and outside the corporate health-system pressure. Membership is limited — by intent.

I · What Atrium isDirect primary care · membership-basedAtrium Health Society · San Francisco
A practice that doesn't bill insurance.
Atrium is a Direct Primary Care practice. We charge a flat monthly membership; we do not bill your insurance. The model lets us cap each physician's panel at 320 patients (vs. 2,500 in fee-for-service), spend an hour with you when you visit, and answer the phone when you call.
Members keep their insurance for procedures, specialists, hospitalization, and prescriptions. Atrium is an addition to your insurance, not a replacement. We coordinate all outside care personally — your physician calls the specialist, reads the note, and tells you what it means.
“The 15-minute visit is not the right tool for taking care of human beings. We built Atrium because we knew a different shape was possible.”
— Dr. Anna Reyes · founding physician

What membership actually means.
II
Direct access, always.
Your phone has your physician's mobile. Same-day visits when needed; same-hour video when something is acute. Members report messaging the doctor directly an average of 1.4 times per month.
III
Coordinated outside care.
Your physician personally calls the specialist, hands off the chart, and reads the consult note. We do not deliver every type of care; we coordinate every type of care that matters.
IV
Privacy as default.
Closed-record practice; we work outside corporate health systems. Records belong to you. We share with consent only — never on a default. Members travel and we travel with the chart.
III · The physiciansVolume IV · 2026Atrium Health Society · San Francisco
Three physicians. One panel each.
Each physician at Atrium runs a closed panel. When a panel is full, it stops accepting new members until a current member leaves the practice. We have not run a Groupon. We will not.

“I tore my ACL on a Saturday. I texted Dr. Reyes from the trail. By Sunday morning she had me booked with the surgeon she trusted, who had operated on her own son. She read the operative note and called me on Wednesday to walk me through the rehab plan. I have never had care like this in my life.”
