We mourn the loss of our trusted advisor, sage consultant, and dear friend, Dr. James Caridi. As an esteemed member of our Medical Advisory Board since its inception, Jim acted as a mentor, teacher and a strategist for our company and its employees. He was humble, approachable, and wise, and he made time for anyone who asked for it. We are thankful for his many contributions to our growth and success, but mostly we are thankful that we were able to work closely with one of the most caring and compassionate physicians in the history of the profession.

Jim fought a long and difficult battle, while performing full-time duties as a practicing Interventional Radiologist, Chair of the Department of Radiology at Tulane University School of Medicine, and simultaneously leading a cancer support group that touched the lives of many. He will be missed. May he now rest in peace.
