Dr. Jason A. Diaz received his Bachelor of Science degree in Business from Wake Forest University in 1998. He went on to get his MD from the Medical College of Georgia in 2003. Dr. Diaz completed both an internship in General Surgery and a residency in Otolaryngology at the University of Utah here in Salt Lake City. He then pursued a fellowship in Head & Neck Surgical Oncology and Microvascular Reconstruction at the University of Pennsylvania. During his time in Philadelphia, he also served as Instructor of Otolaryngology at the Hospital of the University of Pennsylvania. In July of 2009, Dr. Diaz accepted a position as Assistant Professor of Head & Neck Surgical Oncology and Reconstruction within the Department of Otolaryngology at Washington University in St. Louis. He held that position for 5 years. In July of 2014, he moved his family to Utah and joined the Ear, Nose & Throat Center.
His clinical interests include management of benign and malignant tumors of the head & neck, thyroid and parathyroid disease, melanoma and other advanced cutaneous malignancies, salivary gland disorders, paragangliomas, and other skull base tumors. He has special expertise in the fields of minimally-invasive transoral laser excision, transoral robotic surgery, and conservation laryngeal tumor resection. Dr. Diaz is part of the most experienced community-based Head & Neck Microvascular Reconstructive team in the state. He is also one of the few surgeons in the Intermountain West that routinely performs sialendoscopy and ultrasound of the head & neck.
Dr. Diaz has done research in the fields of cancer therapy, transoral robotic surgery, rare head & neck tumors, patient safety, and complex head & neck reconstruction. He has published 24 articles in peer-reviewed medical journals, and has several more that are currently in press. He also co-authored two chapters in the authoritative text on transoral robotic surgery by Drs. Weinstein and O’Malley. He has given over a dozen presentations at national and international Society meetings, as well as countless other invited lectures at local and regional medical gatherings. He is currently involved in research looking at optimal ways to reconstruct throat and scalp defects. Since 2008, he has reviewed manuscripts that were submitted for publication to several major medical journals.
Dr. Diaz is a fellow of the American College of Surgeons, the American Academy of Otolaryngology – Head and Neck Surgery, and the American Head & Neck Society. He holds positions on several Committees within those organizations. Dr. Diaz is Chief of Otolaryngology at Intermountain Medical Center, and Director of Head & Neck Oncology at Jordan Valley Cancer Center. He is an active member of both the Jordan Valley Cancer Committee and the Huntsman-Intermountain Cancer Care Program.
Dr. Diaz loves living in Utah with his wife, Lynn, and their two sons, Tyler and Vaughn. In his free time, he enjoys hiking, skiing, camping, keeping fit, playing guitar, and spending time with his family.
