Portrait of Andrew Pumerantz

Andrew S. Pumerantz, DO, MPH, is Professor of Population Health Science, Internal Medicine, and Infectious Disease at Western University of Health Sciences College of Osteopathic Medicine of the Pacific (WesternU/COMP), where he also directs the Department of Population Health Science. Pumerantz holds an AB from Occidental College, a DO from Philadelphia College of Osteopathic Medicine, and an MPH from the University of California, Berkeley, School of Public Health. He completed internal medicine residency and chief residency at Beth Israel Medical Center/Mount Sinai School of Medicine in New York City, and an infectious diseases fellowship at Yale School of Medicine. Pumerantz then spent the next dozen years as a clinical infectious disease specialist, first in Connecticut and then on Long Island, where he also founded a travel medicine clinic.

In 2007, he joined the full-time faculty at WesternU/COMP as Associate Professor of Internal Medicine and Chief of the Division of Infectious Disease. From 2008 through 2012, he served as Chair of the Department of Internal Medicine, during which time he led an interdisciplinary team to study and co-patent a novel formulation of pegylated liposomal vancomycin designed to target intracellular methicillin-resistant Staphylococcus aureus (MRSA) infection of the lung. His team published their laboratory findings in several microbiology and pharmaceutical science journals, including Antimicrobial Agents and Chemotherapy. As Internal Medicine Chair, Pumerantz established the divisions of endocrinology, nephrology, and cardiovascular disease, which helped transform the WesternU/COMP curriculum and provide resources to launch the Western Diabetes Institute (WDI), an integrated practice and research unit, in 2009. At the WDI, he created the Diabetes Cross-Disciplinary Index (DXDI©), a balanced health scorecard and shared decision-making tool. Pumerantz oversaw the WDI’s diabetes research registry performing numerous observational studies designed to better understand the phenotypic heterogeneity of type 2 diabetes in populations facing significant health disparities while living within an urban environment. He collaboratively published a strategy for integrating standardized screening for periodontal disease as part of the management of adults with type 2 diabetes using the DXDI©, which in turn informed the first internationally standardized set of person-centric outcomes for diabetes.

In 2015, Pumerantz was promoted to Full Professor at WesternU. Three years later, he established the Department of Population Health Science. In fall 2021 as an Adjunct Professor at CGU/SCGH, he helped develop and launch the DO/MPH Dual Degree Program, which he co-directs. The program has enrolled 60 students over its first four annual cohorts, graduating the initial four DO/MPH recipients in May 2024. Professor Pumerantz is a Fellow of the American College of Physicians and an Honorary Member of the Delta Omega Honorary Society in Public Health.
