Our Leadership

Aaron Rossi, MD

Aaron Rossi, MD, CEO of Reditus Laboratories, LLC. He graduated from Elmhurst College in 2006 and received his medical degree from the University of Sint Eustatius School of Medicine in 2012. While still in medical school, Dr. Rossi discovered his passion and unique aptitude for the business management of private medical practice. Since graduating from medical school, Dr. Rossi has served in multiple capacities across the health care continuum, allowing him to expand his knowledge and develop a diverse skillset. Dr. Rossi was driven by his passion to help private physicians navigate the ever-changing health care landscape. He developed a proven model for private practice management and continued to develop his model as he grew a Central Illinois single-provider practice into a robust multi-specialty group. He quickly quadrupled the practice’s revenue in less than five years. Dr. Rossi believes staying in touch with physicians who provide direct patient care allows him to better understand the challenges that private practice physicians experience every day. His main goal, which provides his drive, is to help keep doctors autonomous. He opened Reditus Laboratories in 2019.
