Dr. Javier Alonso
Dr. Alonso was born in Bilbao, Spain, and came to the United States as a cardiovascular surgeon. He completed his board certification in general surgery at the University of Missouri and his cardiothoracic board certification at the University of California – San Diego. He worked with world-renowned physicians in California, such as Dr. Leonard Bailey at Loma Linda University, where he worked with a multidisciplinary pioneering team to bring infant heart transplantation to reality. After years of dedicating time to training and research, he moved to Texas, opened his own Vein & Vascular practice, and later founded Oceana Luxe Medspa.
He has devoted his life to enhancing blood flow to arteries and veins throughout the body. As a founder of treating venous insufficiency, Dr. Alonso uses minimally invasive treatments to address varicose veins. He is passionate about helping patients feel better and alleviate their symptoms. Getting rid of painful and noticeable varicose veins helps patients feel better and improves their quality of life.
