Rodeo Abrencillo, M.D. works as an Assistant Professor of Medicine at McGovern Medical School at UTHealth and as a pulmonary and critical care physician with UT Physicians since 2017.  He was awarded his medical degree from the University of the Philippines-Manila.  He then proceeded and completed his internal medicine residency and pulmonary/critical care fellowship in Henry Ford Hospital/Wayne State University in Detroit, Michigan.

Dr. Abrencillo has always aspired to be a clinician-educator and has thoroughly enjoyed interacting with medical students, residents and fellows. He believes that inspiring young physicians to strive towards knowledge, to cultivate perseverance and to foster respect for human dignity will help them provide the best care possible. During his 2 years as a chief fellow, he helped developed different activities for fellows that addressed pulmonary and critical care basic knowledge assessment, skills development in communication, procedural competency, disease and resource management, and understanding quality/feedback system. As a UT faculty member, he had won the Pulmonary and Critical care Fellowship Teaching Excellence Award and Dean’s Teaching Excellence Award. He also helps the division in educating medical students in outpatient pulmonary topics, hands-on ultrasound sessions and critical care simulation.

Dr. Abrencillo is also passionate about patient safety. He believes a culture of safety should permeate all aspects of care as this will promote a system that is reliable, equitable, patient centered, and safe for every patient.

His clinical areas of interest are interstitial lung diseases, pulmonary fibrosis, obstructive lung diseases, exercise physiology, sepsis, mechanical ventilation, shock states and acute respiratory distress syndrome. He is currently the medical director of Clinics of Interstitial Lung Disease and the medical director of Pulmonary Fibrosis Foundation Clinical Care Network at UTHealth. He also has special interest in health disparities.

He enjoys spending time with his family during his spare time. He also likes watching movies, singing and is currently rediscovering his love for writing.
