  • Aaron Clark, MD
    Dr. Aaron Clark is a neurosurgeon specializing in minimally invasive outpatient procedures for lumbar and cervical herniated discs and stenosis, as well as minimally invasive lumbar fusion surgery. These procedures are associated with shorter recovery times and less postoperative pain than standard surgeries, and almost all patients can return home the same day.
