About Dr. Eric Arias

Denver, CO Neurosurgeon

Dr. Eric J. Arias, Neurosurgeon

Dr. Eric Arias is a compassionate, relatable, and engaging surgeon focused on returning patients to an active and fulfilling lifestyle. Working as a team along with his patients and loved ones, Dr. Arias navigates through all possible surgical and non-surgical options in a comprehensible manner to develop a thorough treatment plan.

Patients with lesions affecting the blood vessels of the brain and neck, such as aneurysms, arteriovenous malformations (AVMs), and carotid stenosis, greatly benefit from Dr. Arias' sub-specialized training. Traditionally, neurosurgeons provided open surgery for these lesions, while radiologists were able to present less invasive options by accessing arteries in the patient's groin or wrist. Dr. Arias trained as both a neurosurgeon and radiologist, so he can provide both options in a single visit, giving an unbiased and comprehensive perspective.

Education and Academic Achievements

Dr. Arias received his Bachelor of Arts and Science from Washington University in St. Louis and completed his Doctor of Medicine at Columbia University College of Physicians and Surgeons in New York. He then returned to Washington University for residency training in Neurological Surgery, which included a seven-month experience as Registrar in Neurological Surgery at Beaumont Hospital in Dublin, Ireland. He then remained at Washington University for an Endovascular Surgical Neuroradiology fellowship at the renowned Mallinckrodt Institute of Radiology. He maintains a focus in cerebrovascular neurosurgery, with numerous research projects and publications in leading journals.
