Internal medicine with subspecialty depth in geriatric and preventive care anchors the Bankers Hill practice of Dr. Banita Kooner, DO at Sharp Rees-Stealy's Fir Street location in downtown San Diego. Complex multi-system cases requiring endocrinology or rheumatology workups route through the same Sharp Rees-Stealy referral network that includes Justin M. Nowell, MD for in-system specialist coordination. Her MPH in Epidemiology and Biostatistics from the University of Illinois informs a data-driven approach to chronic disease tracking across a panel of adult patients in the 92101 zip code. Musculoskeletal complaints evaluated at this Fir Street office often warrant concurrent spinal assessment, a diagnostic pathway shared with Dr. Brian Garrett office in the Bankers Hill chiropractic community. The facility specializes in comprehensive geriatric assessment using validated MMSE and MoCA cognitive instruments, gait-speed analysis, and multi-drug interaction reconciliation under AGS Beers Criteria protocols.
