Dr. Yonas obtained his medical degree from The Ohio State University. He completed an internship and residency in neurosurgery at Case Western Reserve University and also served in the U.S. Air Force as a flight surgeon. He later completed fellowships in microsurgery in Zurich and in Pittsburgh. He joined the University of Pittsburgh faculty in 1978, became a tenured professor in 1988 and was named the Peter J. Jannetta Professor of Neurosurgery in 1995. He served as the vice chair of the department and the Director of Cerebrovascular Surgery until he moved to the University of New Mexico as the first chair of the new Department of Neurosurgery.
Based upon a spine program that integrated physiatry as a core element, the department received a donation from Dr. Anthony Young of 2.5 million dollars to establish the first neurosurgical endoscopic spine center. The department was an active participant in development of the UNM Pain Center and the UNM Rehabilitation Center.
Dr. Yonas was the co-director of the neuro dedicated 24 bed ICU where he helped develop a state of the art program for neuro monitoring. Dr. Yonas brought Mark Krasberg, PhD physicist to UNM to integrate all data streams from an advanced multimodal monitoring program. Dr. Krasberg developed the first on line system for data acquisition but also for advanced integration of data streams.
Yonas was the principal investigator on a $15.1 million Centers for Medicare and Medicaid Services Innovations Grant awarded in September 2014. The three-year Access to Critical Cerebral Emergency Support Services (ACCESS) grant puts state-of-the art telehealth technology in 30 New Mexico hospitals to provide emergent neurological and neurosurgical consultations. By combining an intense educational program with the consultative services the program improved clinical outcomes in rural hospitals and saved the health care system 10’s of millions of dollars due the avoidance of a high percentage of remote transfer. ACCESS integrated a bundled payment model that provided adequate funding for on-going education as well as adequate payment to support
