Internal medicine care for adults anchors Gross David E MD at 2740 First Avenue in Hillcrest, a solo primary-care office serving the 92103 corridor. Abnormal kidney function found on routine internal-medicine panels — rising creatinine, proteinuria, resistant hypertension — moves into the CKD workup managed down the block at Balboa Nephrology - Hillcrest. The panel covers diabetes management, hypertension titration, thyroid workups, annual physicals, and preventive screening for adult patients. Neurological findings surfacing during a physical — tremor, unexplained headache, suspected TIA — route to Neurology Medical Clinic for EEG and MRI follow-up within the same Hillcrest medical corridor. The practice coordinates medication reconciliation for seniors managing multiple chronic conditions across cardiology, endocrinology, and nephrology specialists.
