Meet the Staff

  • Dr. John OróMedical Director

    The Chiari Care Center was founded by Dr. John Oró, neurosurgeon, the Medical Director of Neurosciences at The Medical Center of Aurora.

    Dr. Oró's commitment to advancing Chiari care developed during his tenure as Professor and Chief of Neurosurgery at the University of Missouri. He recalls that, "In 1998, I developed a special interest in Chiari I Malformation because I saw that many people were not receiving adequate evaluation and treatment." Since his initial interest, Dr. Oró's dedication to providing the best surgical procedures and patient care has increased. In 2005, he relocated to Colorado to continue his practice in neurosurgery.

    As the Medical Director of Neurosciences at The Medical Center of Aurora, Dr. Oró's expertise covers a variety of neurological disorders, including brain tumors, cerebral aneurysms and disorders of the spine. His unique dedication to aiding those afflicted with Chiari I Malformation has made him one of the most sought after surgeons in the nation.
