Internal medicine for adults in the Santa Clarita Valley.
Dr. Nastran Hashemi, M.D., MHA is board-certified by the American Board of Internal Medicine, with more than 20 years in medicine and residency training through the UCSF Fresno program.
What an internist does
Internists are specialists in adult medicine. The training goes deep on the conditions that accumulate over a lifetime — heart disease, diabetes, hypertension, thyroid and hormone disorders, kidney and liver disease — and on how those conditions interact with one another.
Where a general practitioner treats broadly across all ages, an internist is the physician you want when your health picture has more than one moving part.
