Under his leadership, Symbiosis Inc. leverages advanced technology, such as telemedicine, to provide urgent care, mobile urgent care, and both ground and air ambulance services outside traditional hospital settings. The company’s innovative “treat, no transport” or “treat and release” approach allows patients who do not require hospitalization to receive necessary care at the scene, thereby preventing unnecessary admissions.
Initially an emergency medical technician at Symbiosis Inc. from 2007 to 2010, Dr. Grange acquired significant expertise in emergency medicine. Concurrently, he held the positions of medical director for both the Yucaipa Fire Department and Highland Fire Department under CAL FIRE and the State of California between 2008 and 2022.

He taught as an assistant professor at Loma Linda University in Loma Linda, California, from 1998 to 2003, before being promoted to associate professor of emergency medicine until 2000, preparing future medical professionals for careers in health care. He joined Loma Linda University Health in 1999 as the emergency medical services director, remaining in position until 2015. As the director until 2012, Dr. Grange established one of the nation’s first programs dedicated to training emergency physicians in pre-hospital and out-of-hospital care, preceding formal approval by the Accreditation Council for Graduate Medical Education. This pioneering effort remains a source of great pride for him. Additionally, Dr. Grange founded the Emergency Medical Services fellowship at Loma Linda University in 2004.
