Dr. McWilliams obtained his Bachelor of Science in Biology at Truman State University in Missouri, where he graduated valedictorian and Summa Cum Laude. He then attended the David Geffen School of Medicine at UCLA, where he received multiple letters of distinction and was selected for the Alpha Omega Alpha National Medical Honor Society. After completing a transitional internship at St. Vincent's Hospital in New York City, Dr. McWilliams returned to UCLA for radiology residency. There he served as Chief Resident, and also received awards for Outstanding Radiology Resident and Outstanding Graduating Senior Resident. He then remained at UCLA for interventional radiology fellowship, at which time he also served as Chief Fellow. Upon completion of his fellowship, Dr. McWilliams accepted a faculty position in the interventional radiology department at UCLA. There he splits his time between angio/interventional procedures and cross-sectional interventional procedures, with a focus on HHT, interventional oncology, prostate embolization, vascular disease, dialysis work, and liver interventions.
