Gulf Regional Research & Educational Services

Gulf Regional Research & Educational Services (GRRES) is a clinical research organization and site based in Metairie, Louisiana, specializing in cardiovascular and metabolic health. Led by Dr. Thomas D. Giles, the organization conducts Phase 4 clinical trials and mechanistic studies focusing on hypertension, arterial stiffness, and Type 2 diabetes. GRRES has notably investigated the physiological effects of SGLT2 inhibitors like dapagliflozin and beta-blockers like nebivolol on blood pressure regulation and endothelial function. The entity frequently collaborates with academic institutions such as the Tulane University School of Medicine to advance clinical understanding of cardiovascular risk factors. Through its research, GRRES provides critical data on the mechanistic pathways of established therapies in real-world patient populations.
