California medical license G136006 and board certification from the American Board of Psychiatry and Neurology in Neurology, paired with United Council for Neurological Subspecialties certification in headache management, anchor Suzan Khoromi at 200 W Arbor Dr inside the UC San Diego Hillcrest medical center. Subspecialty focus runs through neuropathic pain, migraine, trigeminal neuralgia, facial pain, and secondary headaches in pregnancy and the puerperium, a chronic-pain-and-headache lane that interfaces directly with interventional teams at The Pain Center San Diego when nerve blocks or infusions become indicated. Multilingual capacity in Farsi, French, and Spanish broadens access for patients from Hillcrest's diverse immigrant communities who present with chronic headache disorders that primary care has not been able to crack on its own. Cross-system affiliations with both UC San Diego Medical Center and Scripps Mercy Hospital give the practice dual hospital admitting privileges, with internal-medicine referrals routing through groups including UC San Diego Medical Center-Internal Medicine Group Practice on the same Hillcrest campus. The most diagnostically demanding referrals involve atypical headache syndromes layered onto autoimmune disease, intracranial hypertension, or pregnancy-related vascular changes, where MRI interpretation, lumbar puncture findings, and the published clinical-research literature must converge on a single treatment plan.
