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.

Clark earned his medical and postdoctoral degrees from Virginia Commonwealth University. He completed his neurosurgery residency at UCSF, where he developed his interest in spine surgery and began publishing research on spinal oncology, spine biomechanics, spinal deformities and neurophysiological monitoring during spine surgery. In 2014, he completed a fellowship in minimally invasive spine surgery at the Semmes Murphey Neurologic and Spine Institute in Memphis, Tennessee, under the mentorship of Dr. Kevin Foley, a pioneer of minimally invasive spine surgery.
