California Neurosurgical Institute

California Neurosurgical Institute is a private U.S. neurosurgery and spine care practice that provides diagnosis, surgical treatment, and ongoing care for brain, spine, and peripheral nerve disorders. The organization appears to operate as a multi-site physician practice in California, led by founder Dr. Mark Liker, with services centered on minimally invasive and open neurosurgical procedures rather than drug development. Its clinical offerings include treatment for brain tumors, spinal disorders, traumatic brain injury, trigeminal neuralgia, and related neurologic conditions. Publicly available information indicates locations in Valencia, Encino, and Bakersfield, and a for-profit operating model focused on direct patient care. This is a healthcare services organization, not a biotech or pharmaceutical company with a therapeutic pipeline.
