Dr. Ramon Castello is a graduate from University of Valencia School of medicine in Spain. He completed his cardiology training in Pamplona Spain, before coming to the USA. Most of his career was spent in Academic Medicine. He became Assistant Professor of Medicine at St Louis University, then Associate Professor at Case Western Reserve University in Cleveland and finally, Professor of Medicine at Mayo School of Medicine. He was the Director of the Echocardiography Laboratory at Mayo Jacksonville for 7 years. Since 2008 he has been in private practice at Memorial hospital, where he is the Director of Non-invasive cardiology.
He is a world-known echocardiographer and has over 200 scientific publications. He was the President of ICAEL, the national organization that grants accreditation to echocardiography laboratories nationwide. He has been a board member of the American Society of Echocardiography and chair of the Fellows of the American Society of Echocardiography Committee. Currently, he is a member of the National Board of Echocardiography, the organization that grants echocardiography board certifications to qualified physicians.
He is passionate about Cardiology and specifically echocardiography. He feels that “cardiac ultrasound can teach us almost everything about somebody’s heart.” Echocardiography is at the center of all cardiology subspecialties and is an ancillary tool to all of them. “We help everybody, but we need to provide an excellent service.” Therefore, providing high quality echocardiography is a must. He has a great interest in multiple areas of cardiology, including structural heart disease , heart failure, stroke , hypertension, and autonomic dysfunction.
He is one of the few Spanish speaking cardiologists in Jacksonville. A lot of Spanish patients are bilingual, but they feel better talking about their health in their native language. The Spanish population is growing significantly in Northeast Florida To accommodate this need Dr Castello has a full team of Spanish speaking providers.
