Dr. Ruben Diaz was the Director for Children’s Lung Specialists along with the Cystic Fibrosis Center before his passing in December of 2004 at the age of 51. At that time he was one of two practicing pediatric pulmonologists in the Las Vegas Valley. During his 14 years as a Las Vegas pediatrician, he helped develop the Lied Pulmonary Clinic at the University Medical Center and was involved in multiple clinical drug trials and research projects regarding the development of improved treatments for children with cystic fibrosis, asthma, exercise induced bronchospasms, and other pulmonary disorders. Dr Diaz received a number of awards, including Physician of the Year in Pediatrics. Dr. Diaz treated every child the same whether their family could pay for medical care, their families were too poor to pay, or if they were part of an immigrant family speaking only Spanish. Dr. Diaz was also fluent in Spanish. Dr, Diaz never lost his optimistic view even with the most challenging cases. He will be remembered for his remarkable compassion, generosity and tireless advocacy for children.
