Sara Roldan Ramos was the co-founder of Cardiac Health & Performance Ltd. and her passion for cardiology and cardiac surgery was instrumental to the early success of our work. Sara was a childrens heart surgeon and excellent researcher in this field. Her clinical and research expertise shaped what Cardiac Health & Performance Ltd. stands for today. Sara tragically died in a car accident in 2018, cutting short the promising career of a very bright mind and wonderful human being.
