Doctors in Fontana, CA
Active healthcare providers in Fontana sourced from the CMS NPPES weekly file — no proprietary ratings, no editorial scores. NPI counts, specialty distribution, and primary practice addresses refreshed each release.
2,932 healthcare providers across 20 specialties
Fontana, California appears in the CMS National Plan and Provider Enumeration System with 2,932 registered healthcare providers spanning 20 distinct NUCC-taxonomy specialties. This count includes every individual clinician who has applied for an NPI and listed a practice address in Fontana — physicians, dentists, nurse practitioners, physician assistants, chiropractors, physical therapists, optometrists, psychologists, podiatrists, and every other credentialed provider type CMS tracks. It does not measure hospital beds, urgent-care capacity, or whether a given clinic is accepting new patients; it measures the pool of professionals with current NPI enrollment and a Fontana practice location on file.
The provider mix in Fontana is weighted toward Pharmacist (228 clinicians, followed by Student in an Organized Health Care Education/Training Program with 212 and Family Medicine Physician with 187). That distribution reflects how NPPES records specialty: providers self-select a primary taxonomy code, so a family physician who also practices geriatrics will show up under whichever NUCC code they registered first. Relative to California's population, Fontana reports roughly 7.5 providers per 100,000 residents using the state-level denominator, which is a rough proxy rather than a precise access-to-care measurement; the true catchment area of any {cityName} clinician extends beyond the municipal boundary.
For Fontana patients, this directory is most useful as a starting shortlist — searching by specialty narrows the 690-taxonomy roster to clinicians with the relevant training, and each provider page links to NPI, state licensing boards, and the NPPES registry for credential verification. Important: PlainDoctor is a directory of publicly available CMS government data, not a review site, a ranking, or medical advice. NPPES data is self-reported and refreshed monthly, so listing details may be out of date; call the practice directly to confirm the provider is still there, accepts your insurance, and is taking new patients. Nothing on this page substitutes for consulting a licensed clinician about your personal health decisions.
