Dr. Oron Frenkel completed his MS and MD simultaneously at the University of California Joint Medical Program in Berkeley and San Francisco, completing his residency in Emergency Medicine followed by a fellowship in Point-of-Care Ultrasound at Alameda County Medical Center in Oakland, California. He moved to British Columbia with the goal of increasing use of point-of-care ultrasound across the province, especially among rural practitioners. An avid educator, Dr. Frenkel is constantly evaluating the best teaching methods for disseminating this technology, how to measure competency in its practice, and its effects on outcomes for individual patients. Dr. Frenkel serves as Chairman of the Clarius Medical Advisory Board.
