Simkin Kostrinsky, DO has practiced board-certified primary care through Sharp Rees-Stealy since 2002 on Grossmont Center Drive. Her all-ages patient panel includes pediatric well-child checks, adult chronic disease management, and geriatric care, with routine vision screening coordinated through La Mesa optometric providers such as Grossmont Vision Center Optometry near the Grossmont medical complex. Simkin Kostrinsky earned her Doctor of Osteopathic Medicine degree from Western University of Health Sciences, College of Osteopathic Medicine of the Pacific, in 2001.
