E. Marc Mariani, MD, is a highly-skilled orthopaedic surgeon with more than 30 years of experience. Dr. Mariani graduated from the University of Utah Medical School before completing an orthopaedic surgery residency at the Mayo Clinic. After residency, he accepted the opportunity to stay on staff at the Mayo Clinic and Mayo Medical School, before returning to Salt Lake City where he has practiced since 1989.

For Dr. Mariani, the needs of his patients always come first. He and his team of specialists strive to efficiently provide the latest in proven surgical technology in a friendly manner. However, Dr. Mariani believes surgery should only be considered after all appropriate non-operative measures have been considered. He finds helping patients fully resolve orthopaedic problems and get back to an active lifestyle extremely rewarding.

Dr. Mariani enjoys golf and skiing in his free time. He and his wife Michelle have been married 42 years and are the parents to three children.
