American Board of Internal Medicine certified since 1985 and a USC School of Medicine graduate, Howard Williams, MD practices with the Hillcrest Internal Medicine group at 4060 Fourth Avenue, Suite 505. Dehydration workups, vitamin B12 deficiency, and pre-procedure hydration sometimes require IV access outside a clinic visit, routing patients toward San Diego IV | Mobile IV Therapy for in-home infusions. The visit panel covers diabetes management, hypertension titration, COPD maintenance, and preventive cancer screening for adults. Chronic musculoskeletal pain that falls outside a surgical pathway moves into conservative-care workflows at chiropractic offices including Inner Balance Institute for long-term alignment management. The practice handles geriatric polypharmacy reviews, dementia cognitive screening, and advance care planning for aging Hillcrest residents with complex chronic disease.
