              Dr. Angela Rodriguez-Wong became interested in medicine at an early age and in 1987 received her medical degree from the Instituto Technologico de Santo Domingo in the Dominican Republic. Shortly after coming to the United States, her interests led her to the noninvasive vascular lab. In 1995, Angela earned the Registered Vascular Technologist (RVT) credential through the American Registry of Diagnostic Medical Sonographers (ARDMS) and, soon after it was offered, she obtained the Registered Physician in Vascular Interpretation (RPVI) from the Alliance for Physician Certification and Advancement (APCA). By 2000, Dr. Rodriguez-Wong was teaching and training technologists and physicians and was instrumental in developing and teaching the NAVIX Vascular Interpretation Preceptorship. Since the Preceptorship began in 2007, Angela has trained close 1,000 physicians in the interpretation of noninvasive vascular testing, continuing to conduct research and perform patient exams on a daily basis because she “loves working with patients and aiding the physician with the diagnosis.”
