Prior to his latest employment at Simi Valley Hospital, Remboldt served as vice president of Adventist Health’s Rural Health Clinic Network, which recorded sustained growth and a net profitability of $25 million under his leadership. Remboldt has also been a vice president at Glendale Adventist Medical Center and a chief executive officer for both Sonora Community Hospital and Hanford Community Hospital. He has held numerous other executive positions in the managed care industry in both Southern California and Central California.

Remboldt holds a doctor of jurisprudence degree from the Willamette University College of Law in Salem, Oregon; a master’s degree in health administration from California State University, Northridge; and a bachelor of science degree in business administration from Loma Linda University in Riverside, California.
