Over the course of a distinguished 45-year career in medicine and healthcare leadership, Dr. Aran demonstrated a steadfast commitment to patient care, education and system-wide improvement before retiring from the field. Most recently, from 2018 to 2021, he served as the associate dean for clinical affairs and chief medical officer at the school of community medicine at the University of Oklahoma, Tulsa Schusterman Center. In this capacity, Dr. Aran oversaw clinical operations and played a pivotal role in shaping the institution's approach to medical education and patient care. His tenure was marked by an emphasis on integrating wellness into the curriculum and supporting both students and faculty in addressing burnout, a subject on which he has become a recognized speaker.

Before this role, Dr. Aran was the medical director of population health management at Blue Cross and Blue Shield of Oklahoma from 2016 to 2018. During this period, he explored how insurance models could better align with population health initiatives, advocating for an expanded definition of healthcare teams that includes not only physicians and nurses but also emergency rooms, hospitals and other entities essential to comprehensive patient care.

In 2015, Dr. Aran held the position of vice president for system quality at Saint Francis Health System, following his service as the senior vice president for quality from 2013 to 2015.

Dr. Aran consistently prioritized making a difference in the lives of patients and their families, a value he instilled in medical students, residents and fellows throughout his teaching roles.

Dr. Aran began his academic career as an instructor in internal medicine at the University of Chicago Hospitals from 1987 to 1988 before advancing to assistant professor between 1988 and 1990. These formative years allowed him to develop his teaching philosophy centered on the "multiplier effect," believing that by mentoring future healthcare professionals, he could extend his positive influence far beyond individual patient encounters.

Dr. Aran was born at the U.S. Air Force Base in Santurce, San Juan, Puerto Rico, where his father served as a captain. His education years later laid a strong foundation for his achievements. He received a Doctor of Medicine from the Roy J. and Lucille A. Carver College of Medicine at the University of Iowa. He then completed a residency in internal medicine on campus in 1984, followed by fellowships in gastroenterology and hepatology at the Pritzker School of Medicine at the University of Chicago in 1987. To further enhance his leadership capabilities, Dr. Aran obtained a certificate in healthcare management from Oklahoma City University in 2018.

Dedicated to organized medicine, Dr. Aran chaired the board of directors for the Oklahoma State Medical Association from 2020 to 2021. In this capacity, he contributed to statewide initiatives aimed at improving physician well-being and healthcare delivery. Beyond his professional responsibilities, Dr. Aran remains actively involved with civic-minded organizations, notably serving on the board of directors for Saint Francis Health System for over a decade.

He also notes his wife's unwavering support and her role as a neuroscientist in sustaining their family's well-being through the years.

Throughout his career, Dr. Aran has witnessed significant changes within the industry, including the emergence of artificial intelligence as a transformative force in healthcare. He recognizes both its potential benefits and challenges, drawing parallels with earlier technological shifts such as the advent of the Internet. Looking ahead, Dr. Aran is dedicated to advancing recognition for caregivers within the healthcare system.
