I am Dr. Daniel Olvera Posada, I studied my medical career at the medical school of the Tecnologico de Monterrey campus Monterrey, after this I decided to make the specialty of urology in Mexico City at the National Institute of Medical Sciences and Nutrition Salvador Zubiran where I spent 5 years. At the end of this stage I chose to do a subspecialty at the University of Western Ontario "Master of Science", where I spent two years. During this period and when I was doing my specialty in Mexico, I was fortunate to enter the world of research. I had the opportunity to publish multiple scientific articles to obtain the SIN 1. I currently reside my specialty in Monterrey, NL at the Zambrano-Hellion Hospital.
