I have been working in the SJD Pediatric Surgery Service since 2016. I have more than 15 years of experience in the profession and extensive training in different fields of the specialty, which I have completed with stays in national and foreign hospitals. I have established as one of my priorities the application and development of less invasive techniques, to allow greater patient comfort and earlier recovery. I have given multiple presentations and courses related to my specialty and I am the author of multiple articles in national and international magazines. I also have a great interest in teaching, research and scientific dissemination and I am a member of various scientific societies. I believe that, as Plato said, "Wherever the art of medicine is loved, humanity is also loved."

I am a specialist in Pediatric Surgery and Urology, minimally invasive surgery: laparoscopy, retroperitoneoscopy, endoscopy, endourology. I have also specialized in hernia, hydrocele, cryptorchidism, hypospadias, varicocele, sacral cyst, vesico-ureteral reflux, pyeloureteral stenosis, megaureter and other complex urological malformations.
