About Us

Mario Gomez, MD

Doctor Gomez joined our clinical staff in 2009. He completed his medical education at Universidad Peruana Cayetano Heredia in Lima, Peru, his post-doctoral training being taken in Internal Medicine at Henry Ford Hospital in Detroit, Michigan. He received his Pulmonary and Critical Care training at the Medical University of South Carolina in Charleston, where he served as Chief Fellow and trained in Interventional Pulmonology.

Dr. Gomez is Board Certified in Internal Medicine, Pulmonary Medicine, Critical Care Medicine, and Interventional Pulmonology. His interests include lung cancer, advanced diagnostic and therapeutic bronchoscopy, endobronchial ultrasound, endobronchial electro-surgery, pleural disease, and sleep-disordered breathing. His research in the field of Interventional Pulmonology has been presented at major national conferences and has been published in renowned medical journals. He is actively involved in the education of Internal Medicine Residents at UTRGV at Doctors Hospital at Renaissance.

Dr. Gomez strives to deliver compassionate, efficient, and up-to-date care to his patients, taking special care in helping them understand the complexities of their diagnostic and therapeutic interventions. When not immersed in his medical duties, Dr. Gomez is an avid traveler and enjoys spending time at South Padre Island with family and friends.
