Principled Care
Concierge internal medicine in San Antonio, Texas. Direct access, unhurried visits, and rigorous adult primary care designed around judgment, continuity, and time.
Our Philosophy
The average primary care physician manages over 2,000 patients and spends about 15 minutes per visit. Sereno was built to change that. A deliberately small panel. Time to listen. Space to think.
Every clinical decision grounded in peer-reviewed research. We follow the evidence — not trends, not protocols, not industry pressure.
Same- and next-day appointments. Visits that last as long as the conversation requires. Direct physician access by phone, text, and email.
We do not mark up supplements. Your physician does not know what you pay. Every member receives the same standard of care.

Your Physician

Founder & Medical Director
Dr. Lopez trained at UT Health Houston McGovern Medical School and completed his residency at NYU School of Medicine, where he remained on faculty as an Assistant Professor of Medicine.
He returned to San Antonio to build a smaller, more deliberate internal medicine practice centered on continuity, access, and careful clinical judgment.
Membership
Your primary care is included. Non-Medicare members pay no visit fees. For Medicare members, membership covers access and clinical care is billed to Medicare.
Reach your physician directly by phone, text, or secure email. Same- or next-day appointments. After-hours access for urgent concerns.
Extended visits. Annual exams, acute care, medication management, in-office procedures, and ongoing chronic disease management.
Dr. Lopez personally manages inpatient care at Methodist Hospitals, and coordinates every specialist referral from first call to follow-up.
Pricing
Membership starts at $125 per month. The floor is deliberately low — not as a discount, but as the mechanism: members who contribute above it fund sponsored memberships for patients experiencing hardship.

Common Questions
Your first visit is a comprehensive intake — not a rushed meet-and-greet. Plan for 60 to 90 minutes. Dr. Lopez reviews your full history, conducts a physical examination, and discusses your health goals.
No. This is not health insurance. Your membership covers your primary care relationship. You should maintain insurance for hospitalization, specialists, imaging, and prescriptions.
Yes. For Medicare Part B members, the membership fee covers concierge access services; clinical services are billed directly to Medicare.
