Fox Medical Centers

What Fox Medical Centers does

Fox Medical Centers operates in the market under the brand JustWell Health (also styled JustWell Medical Group), a privately held, physician-owned primary care practice headquartered in Miami-Dade County, Florida. The company runs six physical clinic locations across Little Havana, Hialeah, Kendall, Miami Lakes, North Miami Beach, and Westchester, delivering primary care, diagnostics, prescription management, and ancillary health services to patients covered under Medicare Advantage, Commercial, Medicaid, and Marketplace (Exchange) insurance plans. The practice was founded in 1987 by Dr. Gerardo C. Perez, D.O., a board-certified family and geriatric medicine physician, and has operated continuously for over 30 years with long-tenured clinical and administrative staff.

The company's core offering is in-person primary care delivered across its multi-site clinic footprint, supported by the third-party healow patient portal (provided by Health eSolutions) for online scheduling, medical record access, and patient communication. A related wellness sub-brand, RenuWell (renuwellfl.com), extends the offering into wellness services. The most significant non-clinical offering is a Management Services Organization (MSO) module marketed through a "Join Our Network" initiative, which provides back-office and operational infrastructure to affiliated providers — effectively positioning the business as both a clinical operator and a platform for provider affiliation. Technology use is otherwise conventional: no proprietary AI, no disclosed API, and no proprietary software products beyond the patient portal integration.

Revenue is generated almost entirely through fee-for-service and capitated insurance reimbursements from patient encounters across the four accepted payer categories, with no publicly disclosed pricing or contract terms. Go-to-market is direct-to-consumer, relying on multi-location physical presence, community reputation, and a website funnel rather than paid acquisition. Operating geographies are limited to Southeast Florida, with no evidence of out-of-state expansion. Ownership remains with the founding physician and operating administration (Mayra Chanza as Administrator), with no venture capital, private equity, or institutional investment disclosed in the source data.
