Dr. Wright is passionate about all things related to physical activity. One of her favorite ways to stay active is by taking a spin class.

Jarett D. Berry, MD, is a Professor and Chairman of Medicine at UT Tyler School of Medicine.  He graduated from UT Southwestern Medical School and subsequently completed internal medicine residency at UTSW and his clinical cardiology and cardiovascular epidemiology research fellowships at Northwestern University in Chicago, IL.  Dr. Berry previously served as the PI of the Dallas Heart Study, a large observational cohort study of nearly 3,000 Dallas County residents designed to characterize the biology of healthy aging.  He leads a nationally recognized program of research as a cardiovascular epidemiologist with a focus on the prevention of cardiovascular disease across the lifespan. He has published over 150 original research articles broadly related to cardiovascular prevention with a particular focus on (1) exercise and heart failure risk and (2) biomarkers. His work has been supported continuously over the last two decades through sustained funding from the NIH and/or the American Heart Association.    

Dr. Berry has collaborated and provided guidance to the Cooper Center Longitudinal Study (CCLS) since 2009. In 2010, he led the integration of the CCLS with Medicare claims files which in turn led to numerous, high-impact publications regarding the effect of exercise on heart failure risk, dementia, healthy aging, and lower health care costs. He currently leads the institute’s research efforts as our Principal Research Consultant. Dr. Berry is also very active clinically, practicing as a board-certified, general cardiologist.  Dr. Berry lives in Tyler, TX, with Ashleigh, his wife, and their 5 children. He is an avid fly fisherman and loves to stay fit by running with his kids who are competitive long-distance runners.
