Matrix Personalized Medicine

What Matrix Personalized Medicine does

Matrix Personalized Medicine LLC operates a single-location concierge primary care practice headquartered at 45 Grove Street, New Canaan, Connecticut, serving affluent individuals and families primarily in Fairfield County. Founded in June 2017 by Dr. Larry Leibowitz, a board-certified family physician who transitioned out of a Stamford Health Medical Group directorship to pursue a membership-based model, the practice is led today by two physicians—Dr. Leibowitz and Dr. Dana Murphy (board-certified Internal Medicine with a secondary certification in Obesity Medicine, joined 2023)—supported by a small staff of 1-10 employees.

The core offering is an annual membership that bundles all in-office services into a single recurring fee, including comprehensive 60+ minute annual health assessments, 30+ minute routine visits, same/next day scheduling, in-office diagnostics (ECGs, urine tests, throat swabs), direct physician access via personal cell phone and email, telemedicine consultations via FaceTime and Skype, house calls when medically appropriate, and care coordination with specialists. The practice has opted out of commercial insurance and Medicare and does not submit claims; insurance still applies for outside services such as lab tests, imaging, specialist visits, and hospitalizations. Underlying technology is minimal: the practice relies on the third-party PatientFusion patient portal and consumer video tools, with no proprietary platform, AI tooling, or data infrastructure disclosed.

Distribution is exclusively direct-to-consumer through the practice's website (mymatrixmd.com), word-of-mouth referrals, patient testimonials, and complimentary meet-and-greet consultations. The practice holds hospital affiliations with Stamford Health, Danbury Hospital, and Northern Westchester Hospital, and its physicians serve as Clinical Assistant Professors at New York Medical College. Ownership is private and held by the founding physicians with no external investors, funding rounds, or parent company disclosed.

Direct peers

• MDVIP: National network of concierge primary care physicians operating on a membership-fee model similar to Matrix, with smaller patient panels, extended visits, and annual wellness assessments. Most directly comparable peer given shared DPC-concierge economics.
• SignatureMD: Concierge medicine conversion and support company that partners with independent primary care physicians to transition practices to membership models. Directly comparable to Matrix's concierge DPC structure and target physician demographic.
• PartnerMD: Membership-based concierge primary care and executive health practice with multiple locations. Comparable in delivering extended-visit, no-copay concierge primary care to affluent professionals.
• Concierge Choice Physicians: Hybrid concierge medicine model provider offering tiered membership options for primary care physicians. Comparable as a peer concierge practice model operating in similar affluent suburban markets.
• Castle Connolly Private Health Partnership: Concierge medical practice associated with the Castle Connolly Top Doctors network, offering subscription-based access to top-ranked physicians. Highly comparable given Matrix's reliance on Castle Connolly recognition for patient acquisition.

Emerging players

• Forward: Tech-forward membership primary care startup offering app-based health management, biometric body scans, and continuous care. Comparable on membership model and affluent target market; differs on tech-forward delivery versus traditional concierge.

Broad incumbents

• ChenMed: Large membership-based primary care provider focused on senior populations with intensive physician-patient relationships. Comparable concierge-style care model at much larger scale, though focused on Medicare Advantage rather than affluent self-pay.
• One Medical (Amazon): Large-scale membership primary care platform now owned by Amazon, serving affluent urban and suburban markets with tech-enabled, extended-visit primary care. Comparable membership economics and target demographic; much larger scale and broader scope.
• Iora Health (now One Medical): Value-based membership primary care model (now part of One Medical/Amazon) serving patients with extended physician relationships. Comparable relationship-driven care model though operating at significantly larger scale.

Regional players

• Stamford Health Medical Group: Hospital-affiliated primary care group in the same Fairfield County geography where Matrix operates; Dr. Leibowitz previously served as its Medical Site Director. Comparable primary care delivery in the same regional market, though operating under traditional insurance-based model rather than concierge.
